Bootstrap CSS CDN - CSS

Bootstrap is a free front-end framework for faster and easier web development. It includes HTML, CSS, and JavaScript components for building responsive and mobile-first websites.

One of the fastest and easiest ways to get started with Bootstrap is to use the Bootstrap CSS CDN. The CSS CDN provides a hosted version of the Bootstrap CSS framework that you can easily link to in your website's code, without having to download or host the files yourself.

Getting started with the Bootstrap CSS CDN

To get started with the Bootstrap CSS CDN, add the following code to the head of your HTML document:

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css">

This code adds a link to the hosted Bootstrap CSS file on the JSDelivr CDN. The @5.0.2 version number specifies the version of Bootstrap you want to use.

Using Bootstrap CSS classes

Once you've added the Bootstrap CSS to your webpage, you can start using the Bootstrap CSS classes to style your HTML elements. For example, you can use the btn class to create a button:

<button class="btn btn-primary">Click me</button>

This code creates a button with the primary color from the Bootstrap CSS theme.

Bootstrap includes many other classes for styling elements like forms, tables, and images, as well as responsive classes for creating mobile-friendly layouts.

Customizing the Bootstrap CSS

While the hosted Bootstrap CSS file is a quick and easy way to get started with Bootstrap, you may want to customize the styles for your website. One way to do this is to download the Bootstrap CSS source files and make changes to the styles in the scss files using a CSS preprocessor like Sass.

Alternatively, you can use the Bootstrap CSS customization tool to generate a custom version of the Bootstrap CSS with your own theme colors and other settings.

Conclusion

The Bootstrap CSS CDN is a fast and easy way to get started with the Bootstrap front-end framework. By linking to the hosted Bootstrap CSS file, you can easily use the Bootstrap CSS classes to style your HTML elements and create responsive and mobile-first websites. To customize the styles for your website, you can download the Bootstrap CSS source files or use the Bootstrap CSS customization tool.
