So, please sit back, grab a cup of coffee, and let's dive into the world of BootstrapVue!BootstrapVue is a popular open-source front-end framework that combines Bootstrap (a front-end UI framework) and vue.js (a progressive JavaScript framework) to create reusable UI components and web applications.It is designed to be highly customizable, allowing developers to easily modify the appearance and behavior of the components to fit the specific needs of their project. It also includes support for CSS preprocessors like Sass and Less, making it easy to customize the styles of the components.Before we start installing BootstrapVue and learning about some components, it will help if you have the following:The first step would be to create a Vue.js project. This is essential for you to integrate BootstrapVue. Create a Vue.js project by running the following commands in your terminal.Note: BootstrapVue does not presently support the stable version of Vue.js 3. To get it working, you'd need to integrate it with the vue2-3 migration build. However, this is not recommended due to recognized limitations with this method. Regardless, you can use the vue2-3 migration build to create a new application by following the steps here.Then navigate into your project’s directory using cd my-project. You can now proceed to integrate BootstrapVue.There are two ways to integrate BootstrapVue into your Vue.js project:Run one of the commands below depending on the package manager you are working with:Visit CdnJS website to get the current CDN link, then open the index.html file in the public folder and add the code below:The code above will pull each package's minified and the latest version into our project, clean and simple!For this article, we will stick to using package managers. Let’s continue setting up the BootstrapVue package we have installed.To set up the Bootstrap and BootstrapVue packages we just installed. In the src folder, you will find the main.js file. Import BootstrapVue, and its CSS files as seen below:In the code above, we registered BootstrapVue in the application's entry point using the Vue.use() function so our application can recognize it.If you have ever used Bootstrap, you will know it uses some pre-built components. This is the same with BootstrapVue. BootstrapVue components are built specifically for Vue.js, making them easier to use and integrate into your Vue.js applications.Some popular BootstrapVue components include buttons, forms, modals, tooltips, navigation menus, carousels, and more. BootstrapVue also includes some unique components not available in standard Bootstrap, such as the BTable component for creating dynamic and interactive tables.BootstrapVue also includes a range of utility classes and mixins that can customize the appearance and behavior of components even further. This makes it possible to create highly customized and unique websites and applications that stand out. Let’s explore some basic BootstrapVue components, including buttons, forms, and cards.BootstrapVue provides a variety of button components that can be used to create different types of buttons with various styles and functionalities. The most basic button component is the b-button, which can be used to create a simple clickable button. Here is an example:This code above will create a primary-colored button with the text "Click me!" — this is because the variant prop is set to primary. You can change the color and style of the button by specifying other variant values, such as danger or success. BootstrapVue also provides other button components that can be used to create dropdown menus, toggle buttons, and more. You can learn more about button components via the BootstrapVue documentation.BootstrapVue provides a variety of form components that can be used to create forms with different types of input fields, labels, and validations. The most basic form component is b-form-input, which can be used to create a simple text input field.Here is an example:The code above will create a simple form requesting the user's email, name, and food choice. We can always customize this form to suit our use-case.BootstrapVue provides other form components that can be used to create radio buttons, checkboxes, dropdown menus, and more. It provides form validation functionality through the v-validate directive, the ValidationProvider, and ValidationObserver components.BootstrapVue provides a variety of card components that can be used to style text, headings, and images. The most basic card component is the b-card, which can be used to display an image, a heading, and text. Here is an example:The code above will create a card component with an image, a title, and some text displayed using the b-card component.BootstrapVue provides other card components that can be used to create headings, paragraphs, lists, and more. BootstrapVue also provides a utility class system for card-related styles, in which you can apply common styles like text color, font weight, and text alignment.BootstrapVue provides many advanced components that can be used to add more complex functionality to your Vue.js applications. Some of these advanced components are modals, carousels, and tooltips.Modals are a popular way to display content in a modal dialog that appears on the current page. BootstrapVue provides a b-modal component that can be used to create modals with various functionalities, such as showing/hiding the modal, changing its size, and adding custom content. Here is an example:The code above will create a button that, when clicked, will show a modal dialog with the title "My Modal" and the text "Hello, world!".BootstrapVue also provides other modal-related components that can be used to create confirmation dialogs, scrollable modals, and more. BootstrapVue also provides events that can be used to trigger actions before and after the modal is shown or hidden.Carousels are a popular way to display a series of images or other content in a rotating carousel. BootstrapVue provides a b-carousel component that can be used to create carousels with various functionalities, such as autoplay, navigation controls, and indicators. Here is an example:This code will create a carousel with three slides containing an image and a caption. BootstrapVue also provides other carousel-related components that can be used to create slide transitions, fade transitions, and provides events that can be used to trigger actions before and after each slide is shown.Tooltips are a popular way to display additional information when the user hovers over an element. BootstrapVue provides a b-tooltip component that can be used to create tooltips with various functionalities, such as changing the position, adding custom content, and controlling when the tooltip is shown. Here is an example:This code will create a button that, when hovered over, will show a tooltip with the text "Hello, world!".BootstrapVue also provides other tooltip-related components that can be used to create tooltips with HTML content, programmatically show/hide tooltips, and more.Customizing BootstrapVue components allows you to tailor the appearance and behavior of the components to your specific needs. Let’s now learn how to customize two BootstrapVue components, buttons, and modals using examples.BootstrapVue provides many customization options for buttons, such as changing the size, color, shape and adding custom classes or styles. Here is an example of how to change the color and shape of a button using BootstrapVue classes:This code will create two buttons, one with a primary color and a rounded pill shape, and one with a danger color and a square shape. The rounded-pill and rounded-0 classes are BootstrapVue classes that control the border radius of the button.You can also add custom classes or styles to the button by using the class or style attributes:This code will create a success button with a custom class of my-custom-class and a custom style of font-size: 1.2rem;.BootstrapVue provides many customization options for modals, such as changing the size, position, backdrop and adding custom content or styles. Here is an example of how to change the size and position of a modal using BootstrapVue props:This code will create a button that, when clicked, will show a modal dialog with the title "My Modal" and the text "Hello, world!" with a large size and centered position.You can also add custom content or styles to the modal by using slots or the style attribute:This code will create a modal dialog with a custom heading and content, a custom OK button, and a paragraph with custom CSS. BootstrapVue provides powerful styling features that allow you to style your components with CSS easily. In this article, we will provide an explanation of how to style BootstrapVue components using CSS.BootstrapVue components have a set of default styles that you can easily customize. You can apply styles to a component by adding a class or style attribute to the component:In the code above, we've added a custom class of my-custom-class to the button and a custom style of background-color: red. This will change the background color of the button to red.BootstrapVue also supports the use of CSS preprocessors like Sass and Less. Using a preprocessor allows you to write more powerful and modular CSS code. To use a preprocessor with BootstrapVue, you can simply include the preprocessor file in your project and import it into your code:Once you've imported the preprocessor files, you can use their features to style your components. For example, in Sass, you can use variables to define colors and other properties:In this example, we've defined a variable for the primary color, and we've used it to style a custom button with a custom class of custom-button. This will give the button a background color of #007bff (the primary color) and a border radius of 0.25rem.Sometimes you may want to apply styles to a component that only affects that component and not any other components on the page. In this case, you can use scoped styles. Scoped styles are only applied to a specific component and its children.To use scoped styles in BootstrapVue, you can add a scoped attribute to the
