Commonly Used Components

Layout and Grid System with BootstrapVue

BootstrapVue provides a powerful and flexible grid system that helps you create beautiful and responsive layouts with ease. The grid system is built with flexbox and is fully responsive, making it easy to create layouts that look great on all devices.

The grid system uses a series of containers, rows, and columns to layout and align content. The grid is made up of three main components: <b-container>, <b-row>, and <b-col>.

Containers: <b-container>

Containers are the most basic layout element in BootstrapVue. You can choose from a responsive, fixed-width container (that changes its max-width at each breakpoint) or a fluid-width container (that is always 100% wide). You can also choose a responsive container that is fluid until a specific breakpoint.

The default container is a responsive, fixed-width container. You can change it to a fluid-width container by using the fluid prop.

<b-container>
  <!-- Content here -->
</b-container>

<b-container fluid>
  <!-- Content here -->
</b-container>
Rows: <b-row> and <b-form-row>

Rows are wrappers for columns. Each column has horizontal padding (a gutter) to control the space between them. The padding is then countered on the rows with negative margins, which makes all the content in your columns visually aligned down the left side.

You can remove the margin from <b-row> and padding from <b-col> by using the no-gutters prop on <b-row>.

The <b-form-row> component is typically used when laying out forms and has more compact margins than <b-row>.

Columns: <b-col>

Columns must be placed inside a <b-row> component or an element that has the class row applied to it. They must also be placed inside a <b-form-row> component to obtain columns with more compact margins.

Grid Options

BootstrapVue provides several options to customize the grid, such as:

  • Auto-layout columns
  • Equal-width columns
  • Variable width content
  • Responsive classes
  • Reordering and Offsetting columns
  • Margin utilities on columns
  • Nesting grids
Extra small (xs)
<576px
Small (sm)
≥576px
Medium (md)
≥768px
Large (lg)
≥992px
Extra large (xl)
≥1200px
Max container width None (auto) 540px 720px 960px 1140px
Prop cols="*" sm="*" md="*" lg="*" xl="*"
# of columns 12
Gutter width 30px (15px on each side of a column)
Nestable Yes
Offset offset="*" offset-sm="*" offset-md="*" offset-lg="*" offset-xl="*"
Order order="*" order-sm="*" order-md="*" order-lg="*" order-xl="*"

To make the grid responsive, there are five grid breakpoints: all breakpoints (extra small), small, medium, large, and extra large. The grid breakpoints are based on minimum width media queries.

You can use predefined grid classes or Sass mixins for more semantic markup. Keep in mind the limitations and bugs around flexbox, such as the inability to use some HTML elements as flex containers.

Alignment

BootstrapVue provides alignment utilities to vertically and horizontally align columns. You can use the align-v prop on <b-row> for vertical alignment and the align-h prop on <b-row> for horizontal alignment.

Form Components

BootstrapVue provides form components and helper components that can be used to create custom forms with inline styles and validation states. You can use these components with other BootstrapVue form control components to create a consistent and responsive form layout.

When creating forms, it’s important to use the correct type of input for the type of data you want to collect (e.g. email for email addresses, number for numerical information). This will allow you to take advantage of newer input controls like email verification and number selection.

We’ll never share your email with anyone else.

      onReset(event) {
        event.preventDefault()
        // Reset our form values
        this.form.email = ''
        this.form.name = ''
        this.form.food = null
        this.form.checked = []

        this.show = false
        this.$nextTick(() => {
          this.show = true
        })
      }
    }
  }
</script>

 

Bootstrap-Vue provides various form components that help in creating forms for collecting user input. Some commonly used form components include:

  • Form Input: The <b-form-input> component is used to create various types of inputs such as text, password, number, URL, email, search, range, date, and more. You can also use the various props available to add features such as autocomplete, placeholder text, and validation states.

Example:

<template>
  <div>
    <label for="example-input">Enter your name:</label>
    <b-form-input id="example-input" v-model="name" placeholder="Enter your name"></b-form-input>
  </div>
</template>

<script>
export default {
  data() {
    return {
      name: '',
    };
  },
};
</script>
  • Form Select: The <b-form-select> component is used to create custom select boxes using cross-browser custom styles. You can also generate <option> entries based on an array or an array of objects.

Example:

<template>
  <div>
    <label for="example-select">Select your country:</label>
    <b-form-select id="example-select" v-model="selectedCountry" :options="countries"></b-form-select>
  </div>
</template>

<script>
export default {
  data() {
    return {
      selectedCountry: '',
      countries: [
        { value: 'us', text: 'United States' },
        { value: 'ca', text: 'Canada' },
        { value: 'mx', text: 'Mexico' },
      ],
    };
  },
};
</script>
  • Form Checkbox: The <b-form-checkbox> component is used to create custom checkbox inputs and checkbox groups to replace the browser default checkbox input. You can also add features such as switch styling and validation states.

Example:

<template>
  <div>
    <b-form-checkbox v-model="checked" name="myCheckbox">Check me out</b-form-checkbox>
  </div>
</template>

<script>
export default {
  data() {
    return {
      checked: false,
    };
  },
};
</script>
  • Form Textarea: The <b-form-textarea> component is used to create multi-line text inputs with support for auto height sizing, minimum and maximum number of rows, and contextual validation states.

Example:

<template>
  <div>
    <label for="example-textarea">Enter your message:</label>
    <b-form-textarea id="example-textarea" v-model="message" :rows="3"></b-form-textarea>
  </div>
</template>

<script>
export default {
  data() {
    return {
      message: '',
    };
  },
};
</script>
  • Form Datepicker: The <b-form-datepicker> component is used to create custom date picker input form controls, which provide full WAI-ARIA accessibility (a11y) and support internationalization (i18n).

Example:

<template>
  <div>
    <label for="example-datepicker">Select a date:</label>
    <b-form-datepicker id="example-datepicker" v-model="selectedDate"></b-form-datepicker>
  </div>
</template>

<script>
export default {
  data() {
    return {
      selectedDate: null,
    };
  },
};
</script>

Validation

It is important to validate form data before submitting it to the server to ensure that the data entered by the user is correct and meets the required criteria. BootstrapVue provides a way to disable browser native HTML5 validation by setting the novalidate prop to true on <b-form>.

You can also add the validated prop to <b-form> with a value of true to add the Bootstrap v4 .was-validated class to the form, which will trigger the native browser validation states.

All of the form controls support a state prop, which can be used to set the form control into one of three contextual states:

  • false (denotes invalid state) is great for when there’s a blocking or required field. A user must fill in this field properly to submit the form.
  • true (denotes valid state) is ideal for situations when you have per-field validation throughout a form and want to encourage a user through the rest of the fields.
  • null displays no validation state (neither valid nor invalid)

If you want to use a third-party Vue-based validation library with BootstrapVue, refer to the BootstrapVue Form validation reference section.

Form helper components

BootstrapVue provides the following helper components to make it easier to create forms:

  • <b-form-text>: displays help text below an input.
  • <b-form-invalid-feedback>: displays invalid feedback text blocks for input invalid states.
  • <b-form-valid-feedback>: displays valid feedback text blocks for input valid states.
  • <b-form-datalist>: allows you to quickly create a datalist element.

Button Components

BootstrapVue provides the b-button component to create buttons with the styling of Bootstrap. This component can generate either a <button>, <a>, or <router-link> element with various options such as different styles, sizes, and states.

Element Type

The b-button component generates a <button> element by default, but you can also generate an <a> element by providing an href prop or a <router-link> component by providing a value for the to prop (vue-router is required for this).

<div>
  <b-button>I am a Button</b-button>
  <b-button href="#">I am a Link</b-button>
</div>
Type

You can specify the type of the button with the type prop. The type prop can be set to 'button', 'submit', or 'reset'. The default type is 'button'. If you provide an href or to prop, the type prop will have no effect.

Sizing

You can change the size of the button with the size prop. You can set it to 'sm' for a smaller button or 'lg' for a larger button. The default size is 'md'.

<b-row>
  <b-col lg="4" class="pb-2"><b-button size="sm">Small Button</b-button></b-col>
  <b-col lg="4" class="pb-2"><b-button>Default Button</b-button></b-col>
  <b-col lg="4" class="pb-2"><b-button size="lg">Large Button</b-button></b-col>
</b-row>
Contextual Variants

You can change the style of the button with the variant prop. The variant prop sets the Bootstrap v4.3 class .btn-<variant> on the button. The default variant is 'secondary'. You can choose from solid color variants such as primary, secondary, success, danger, warning, info, light, and dark, and outline color variants such as outline-primary, outline-secondary, outline-success, outline-danger, outline-warning, outline-info, outline-light, and outline-dark.

<div>
  <b-button variant="primary">Primary</b-button>
  <b-button variant="secondary">Secondary</b-button>
  <b-button variant="success">Success</b-button>
  <b-button variant="danger">Danger</b-button>
  <b-button variant="warning">Warning</b-button>
  <b-button variant="info">Info</b-button>
  <b-button variant="light">Light</b-button>
  <b-button variant="dark">Dark</b-button>
</div>
Link Variant

The variant prop can also be set to “link” to render a button with the appearance of a link while maintaining the default padding and size of a button.

<b-button variant="link">Link</b-button>

Accessibility

To ensure accessibility, the b-button component uses the href prop to determine the behavior of the component. If the href prop is set to '#', the b-button component will render as a <a> element with a role="button" attribute and appropriate keydown listeners (Enter and Space). This allows the link to act like a native HTML <button> for screen reader and keyboard-only users. When the component is disabled, the aria-disabled="true" attribute will be set on the <a> element.

If the href prop is set to any other value, or if the to prop is used, the role="button" attribute will not be added, and the keyboard event listeners will not be enabled.

active Boolean false When set to `true`, places the component in the active state with active styling
active-class String <router-link> prop: Configure the active CSS class applied when the link is active. Typically you will want to set this to class name ‘active’
append Boolean false <router-link> prop: Setting append prop always appends the relative path to the current path
block Boolean false Renders a 100% width button (expands to the width of its parent container)
disabled Boolean false When set to `true`, disables the component’s functionality and places it in a disabled state
exact Boolean false <router-link> prop: The default active class matching behavior is inclusive match. Setting this prop forces the mode to exactly match the route
exact-active-class String <router-link> prop: Configure the active CSS class applied when the link is active with exact match. Typically you will want to set this to class name ‘active’
exact-path Boolean false <router-link> prop: Allows matching only using the path section of the url, effectively ignoring the query and the hash sections
exact-path-active-class String <router-link> prop: Configure the active CSS class applied when the link is active with exact path match. Typically you will want to set this to class name ‘active’
href String <b-link> prop: Denotes the target URL of the link for standard a links
no-prefetch Boolean false <nuxt-link> prop: To improve the responsiveness of your Nuxt.js applications, when the link will be displayed within the viewport, Nuxt.js will automatically prefetch the code splitted page. Setting `no-prefetch` will disabled this feature for the specific link
pill Boolean false Renders the button with the pill style appearance when set to ‘true’
prefetch
v2.15.0+
Boolean null <nuxt-link> prop: To improve the responsiveness of your Nuxt.js applications, when the link will be displayed within the viewport, Nuxt.js will automatically prefetch the code splitted page. Setting `prefetch` to `true` or `false` will overwrite the default value of `router.prefetchLinks`
pressed Boolean null When set to ‘true’, gives the button the appearance of being pressed and adds attribute ‘aria-pressed=”true”‘. When set to `false` adds attribute ‘aria-pressed=”false”‘. Tri-state prop. Syncable with the .sync modifier
rel String null <b-link> prop: Sets the `rel` attribute on the rendered link

Bootstrap-Vue provides various button components that can be used to create buttons with different styles and functionality. Some commonly used button components include:

Button: The <b-button> component is used to create buttons with support for a handful of contextual variations, sizes, states, and more. You can customize the appearance of the button by using various props such as variant, size, block, and disabled.

Example:

<template>
  <div>
    <b-button variant="primary">Primary</b-button>
    <b-button variant="secondary">Secondary</b-button>
    <b-button variant="success">Success</b-button>
    <b-button variant="warning">Warning</b-button>
    <b-button variant="danger">Danger</b-button>
    <b-button variant="info">Info</b-button>
    <b-button variant="light">Light</b-button>
    <b-button variant="dark">Dark</b-button>
  </div>
</template>

Button Group: The <b-button-group> component is used to group a series of buttons together on a single line. You can also use the vertical prop to stack the buttons vertically.

Example:

<template>
  <div>
    <b-button-group>
      <b-button variant="primary">One</b-button>
      <b-button variant="primary">Two</b-button>
      <b-button variant="primary">Three</b-button>
    </b-button-group>
  </div>
</template>

Dropdown: The <b-dropdown> component is used to create toggleable, contextual overlays for displaying lists of links and actions in a dropdown menu format.

Example:

<template>
  <div>
    <b-dropdown text="Dropdown">
      <b-dropdown-item>Item 1</b-dropdown-item>
      <b-dropdown-item>Item 2</b-dropdown-item>
      <b-dropdown-item>Item 3</b-dropdown-item>
    </b-dropdown>
  </div>
</template>

Link: The <b-link> component is used to generate a standard <a> link or <router-link>. You can customize the appearance of the link by using various props such as variant, size, and disabled.

Example:

<template>
  <div>
    <b-link href="#">Link</b-link>
  </div>
</template>

IconButton: The <b-icon-button> component is used to create buttons with icons. You can customize the appearance of the button by using various props such as variant, size, and icon.

Example:

<template>
  <div>
    <b-icon-button variant="primary" icon="check"></b-icon-button>
  </div>
</template>

These are just a few examples of the many button components available in Bootstrap-Vue. You can find more information about these and other button components in the Bootstrap-Vue documentation.

Understanding Vue.js and Bootstrap 5 Integration

Vue.js and Bootstrap 5 are both popular front-end development technologies that can be used together to create rich and dynamic user interfaces. Vue.js is a JavaScript framework for building user interfaces, while Bootstrap 5 is a CSS framework for styling web pages. By combining these two technologies, you can create fast and responsive web applications that look great and are easy to use.

To integrate Vue.js and Bootstrap 5, you need to include the Vue.js library and the Bootstrap 5 CSS file in your project. You can use a package manager like npm or yarn to install the required packages and include them in your project.

Once you have integrated Vue.js and Bootstrap 5, you can start using the components provided by Bootstrap 5 in your Vue.js application. You can also use the Vue.js directives to bind data to the components, making it possible to dynamically update the content of your web pages.

Advantages of Using Bootstrap 5 with Vue.js

There are several advantages to using Bootstrap 5 with Vue.js, including:

  • Easy to use: Bootstrap 5 provides a large number of pre-built components that are easy to use and customize. You can quickly create complex user interfaces by combining these components with Vue.js.
  • Responsive design: Bootstrap 5 is designed to be responsive, meaning that it adapts to the screen size of the device being used. This makes it easy to create web pages that look great on all devices, from desktop computers to smartphones.
  • Accessibility: Bootstrap 5 includes accessibility features that make it easy to create user interfaces that are accessible to people with disabilities.
  • Highly customizable: You can customize the appearance of Bootstrap 5 components by using custom CSS styles. You can also create custom Vue.js components that use the Bootstrap 5 styles.

Creating Custom Vue.js Components with Bootstrap 5

One of the great things about using Bootstrap 5 with Vue.js is that you can create custom components that use the Bootstrap 5 styles. This allows you to create unique user interfaces that are tailored to your needs.

To create a custom Vue.js component with Bootstrap 5, you need to create a new Vue.js component and include the Bootstrap 5 CSS styles in your project. You can then use the Bootstrap 5 classes in the HTML template for your component to style it.

Here’s a simple example of how you could create a custom button component using Bootstrap 5 and Vue.js:

<template>
  <button class="btn btn-primary">{{ text }}</button>
</template>

<script>
export default {
  props: ['text'],
};
</script>

In this example, we’re using the btn and btn-primary classes from Bootstrap 5 to style the button. We’re also using a prop called text to allow the button text to be dynamically changed.

Migrating from Bootstrap 4 to Bootstrap 5

If you’re currently using Bootstrap 4 in your Vue.js application, you may be interested in migrating to Bootstrap 5. There are a few changes in Bootstrap 5 that you should be aware of, including:

  • New CSS classes: Bootstrap 5 has introduced some new CSS classes that replace some of the classes from Bootstrap 4. You may need to update your

HTML markup to take advantage of these new classes. For example, in Bootstrap 4, the class “d-flex” was used to create a flex container, but in Bootstrap 5, the class “flex-” is used instead.

Improved JavaScript plugins: Bootstrap 5 has improved some of its JavaScript plugins, such as the carousel, modal, and tooltips. These plugins now use vanilla JavaScript, which means that they no longer rely on jQuery. This can result in improved performance and a smaller file size for your application.

CSS custom properties: Bootstrap 5 now uses CSS custom properties, which are variables that can be used in your CSS to make it more flexible and easier to maintain. You can use these custom properties to customize the look and feel of your application without having to write a lot of CSS

Theming and Styling in Bootstrap-Vue 3

Theming and styling are essential parts of any web development project. They help to create a visually appealing and user-friendly interface that enhances the overall user experience. Bootstrap-Vue 3, a popular UI framework, provides developers with various theming and styling options that make it easier to customize the look and feel of their web applications.

Theming Options Overview

Bootstrap-Vue 3 provides several theming options that allow developers to customize the appearance of their web applications. The following table provides an overview of these options, along with a brief description and example:

SCSS Variables Define SCSS variables to modify Bootstrap-Vue 3 styles. $primary: #007bff; @import '~bootstrap/scss/bootstrap';

Built-in Bootstrap 5 Themes

Bootstrap-Vue 3 provides several built-in Bootstrap 5 themes that developers can use to quickly and easily change the appearance of their web applications. These themes include:

  1. Bootstrap – The default theme that comes with Bootstrap 5.
  2. Cerulean – A calming blue theme.
  3. Cosmo – A theme with a modern and clean look.
  4. Cyborg – A dark theme with a futuristic feel.
  5. Darkly – A dark theme with a flat design.
  6. Flatly – A simple and flat theme.
  7. Journal – A theme with a newspaper-like design.
  8. Litera – A theme with a literary feel.
  9. Lumen – A light and airy theme.
  10. Lux – A theme with a luxurious feel.
  11. Materia – A theme with a material design feel.

  22. Yeti – A theme with a cool and snowy feel.

Developers can use these themes by setting the bootstrap property of the BIcon component to the desired theme name. For example:

<BIcon icon="heart" bootstrap="sketchy" />

Creating Custom Themes

Bootstrap-Vue 3 allows developers to create their own custom themes by defining CSS variables. This approach provides maximum flexibility and customization options. Here are the steps to create a custom theme:

  1. Define your CSS variables in your application’s main CSS file. For example:
    :root {
      --primary-color: #007bff;
      --secondary-color: #6c757d;
    }
    
  2. Use the defined variables in your component styles. For example:
    .my-component {
      background-color: var(--primary-color);
      color: var(--secondary-color);
    }
    
  3. Use the bv-theme component to define the custom theme. For example:
    <bv-theme vars='{ "primary-color": "#007bff", "secondary-color": "#6c757d" }'>
      <!-- Your application content goes here -->
    </bv-theme>
    

Styling Individual Components

Bootstrap-Vue 3 provides several ways to style individual components. One way is to use the class and style attributes to apply custom styles. For example:

<b-button class="my-button" style="background-color: red;">Click me!</b-button>

Another way is to use the scoped attribute to apply component-specific styles. For example:

<template>
  <div>
    <style scoped>
      .my-button {
        background-color: red;
      }
    </style>
    <b-button class="my-button">Click me!</b-button>
  </div>
</template>

Accessibility and Responsiveness in Bootstrap-Vue 3

Bootstrap-Vue 3 is a popular UI library for building responsive and accessible applications. The library provides a wide range of features and tools for creating accessible and responsive applications, and this text will provide an overview of the key topics in this area.

Accessibility Features in Bootstrap-Vue 3

Bootstrap-Vue 3 provides a number of accessibility features that help you create accessible applications. One of the key features is support for ARIA attributes, which help provide information to assistive technologies such as screen readers. For example, the aria-label and aria-describedby attributes can be used to provide additional information about an element to assistive technologies.

The library also provides support for keyboard navigation, making it easy to navigate your application using the keyboard. For example, the tabindex attribute can be used to specify the order in which elements are focused when using the tab key.

In addition, Bootstrap-Vue 3 provides a number of components that are specifically designed to be accessible, such as the b-form-input component, which includes support for ARIA attributes and keyboard navigation.

Implementing Responsive Design with Bootstrap-Vue 3

Bootstrap-Vue 3 provides a number of tools and features for implementing responsive design in your applications. One of the key features is the responsive grid system, which allows you to create flexible and responsive layouts that automatically adjust to different screen sizes.

For example, you can use the col and row components to create a grid layout, and use the col-* classes to specify the width of each column in the grid. The grid system is fully responsive, so your layout will automatically adjust to different screen sizes.

In addition, Bootstrap-Vue 3 provides a number of responsive utility classes that you can use to add responsive styles to your application. For example, you can use the d-* classes to show or hide elements based on the screen size, and the text-* classes to control the text alignment based on the screen size.

Best Practices for Accessible and Responsive Applications

When building accessible and responsive applications, it’s important to follow best practices to ensure that your applications are usable by everyone, regardless of their device or accessibility needs.

One of the key best practices is to use semantic HTML elements wherever possible, as this helps provide additional information to assistive technologies. For example, use the <header> and <nav> elements to define the header and navigation sections of your application, rather than using generic <div> elements.

In addition, it’s important to test your application on a range of devices and screen sizes, and to use tools such as screen readers to test the accessibility of your application. This will help you identify any accessibility issues and ensure that your application is usable by everyone.
