The Ultimate Guide to Using Bootstrap Icons in Your Web Projects

Icons are an essential element of modern web design. When used effectively, icons can make interfaces more intuitive, provide visual interest, save space, and even improve website accessibility. Bootstrap icons are one of the most popular and full-featured open source icon libraries available today.

In this comprehensive guide, we‘ll cover everything you need to know to start using Bootstrap icons in your web projects. Whether you‘re a beginner just learning web development or an experienced developer looking to up your icon game, this guide will walk you through all the key concepts and best practices. Let‘s jump in!

What are Bootstrap Icons?

Bootstrap icons are a free, open source icon library featuring over 1,300 high-quality icons. The icons are designed to be used with the Bootstrap front-end framework but can be used with any web project.

Some key features of Bootstrap icons:

  • Extensive selection with 1,300+ icons to choose from
  • Consistent design style that matches the Bootstrap aesthetic
  • Available as icon fonts and SVGs for flexible usage
  • Open source under the MIT license
  • Continuously growing with new icons added in each release

The icon set covers a wide range of categories including UI controls, navigation, alerts, devices, files, and more. Here‘s a small sampling of what‘s included:

Bootstrap icons provide an easy way to add professional, modern icons to your designs without having to source or create assets yourself. The consistent style helps create a polished look and feel.

Getting Started with Bootstrap Icons

Before you can start using Bootstrap icons, you‘ll need to install them in your project. There are a few different ways to do this depending on your setup and preferences.

The easiest way is to simply include Bootstrap icons from a CDN. Add this line to the of your HTML document:

This will load the latest version of Bootstrap icons from the jsDelivr CDN. You can also download the icon font files and host them yourself if you prefer.

If you‘re using a package manager like npm, you can install Bootstrap icons as a dependency:

npm i bootstrap-icons

Then you can import the styles into your CSS:

@import "bootstrap-icons/font/bootstrap-icons.css";

Once you have Bootstrap icons installed, you can start using them with the element:

This will display the alarm clock icon. Simply replace the name after bi- with the specific icon you want to use. You can browse the full list of available icons in the Bootstrap icon library.

Sizing and Styling Icons

By default, Bootstrap icons will inherit the font size and color of the parent element. So a larger parent font size will result in larger icons.

You can set a custom size by giving the icon a specific font size:

This icon will now render at 2rem (32px if default root font size), regardless of parent element.

To change the color, use any CSS that sets the text color, such as:

You can use any of the usual color formats like named colors, hex codes, rgb/rgba, etc.

Here‘s a fun example that combines sizing and colors:

This is just scratching the surface of what you can do by combining Bootstrap icons with CSS. You can use any CSS properties to customize your icons, giving you full control over the look and feel.

Accessibility and Icons

When using icons, it‘s important to consider accessibility for users with screen readers or other assistive devices. Icons alone may not convey meaning to these users.

Bootstrap icons have the aria-hidden attribute set by default:

This tells screen readers to ignore the icon. In most cases, you should pair your icon with text that describes its meaning:

The screen reader will read the text "Add to Cart" and ignore the icon itself.

For cases where you want to use an icon without any visible text, use the aria-label attribute to provide a text alternative:



Here the screen reader will read the aria-label of "Settings" to describe the purpose of this link.

By taking the time to consider these accessibility features, you can ensure your icons are conveying their meaning to all users.

Customizing and Hosting Bootstrap Icons

While the default Bootstrap icon library is already quite extensive, you may have needs for custom icons in your projects. Thankfully, it‘s easy to customize the Bootstrap icon set to fit your needs.

Bootstrap icons are open source under the MIT license, so you‘re free to download and modify them. The Figma and Adobe XD files are available in the GitHub repo, allowing you to open and edit all the icons visually.

After editing the icons to your liking, you can export them as SVGs or font files for use on your website. By hosting the customized icons yourself, you have full control and don‘t have to worry about unexpected changes from Bootstrap updates.

You can even mix and match custom icons with the stock Bootstrap set for a hybrid approach. Host your custom icons separately and include both your custom set and the stock Bootstrap CDN in your project.

SVGs vs Icon Fonts

So far we‘ve focused on using Bootstrap icons as an icon font via the element. However, Bootstrap icons are also available as individual SVG files.

Using SVG versions of the icons looks like this:

So which format should you choose? It depends on your specific needs and constraints.

Icon fonts have some benefits:

  • Simple usage, just add a class to an tag
  • Few HTTP requests since it only loads the single font file
  • Easy to style with text properties like font-size and color
  • Automatic perfect pixel scaling with font sizes

However, SVGs have some advantages as well:

  • Better rendering, especially at larger sizes
  • Animating and transforming individual parts and colors of the icons
  • Can be inlined directly in HTML for fewer HTTP requests
  • More predictable positioning and sizing vs fonts

If you need pixel perfect icons at any size, multi-color icons, or complex animations, SVG is probably the right choice. If you want simple styling and scaling and don‘t mind the quirks of fonts, icon fonts may be a better fit.

Best Practices for Using Icons

To wrap up, here are some tips and best practices to keep in mind when using Bootstrap icons (or any icons):

  • Use icons purposefully and sparingly. Don‘t add icons just to have them, make sure they serve a real purpose in aiding usability or communication.
  • Combine icons with text labels, especially for important actions. Don‘t assume everyone will understand what an icon means in isolation.
  • Provide text alternatives for accessibility. Use aria-label when an icon is used alone without a text label.
  • Adapt icons to your content. If you‘re using an icon to communicate something specific, consider customizing it to better fit your exact use case.
  • Keep icons consistent in terms of size, color, and style. A mishmash of different icon styles can make your UI feel disjointed and confusing.
  • Test your icon usage with real users. Observe their behavior and gather feedback to ensure your iconography is working as intended.

By putting these principles into practice, you can harness the power of Bootstrap icons to enhance your web projects. Well-executed icons can go a long way in improving the user experience and polish of your websites and apps.
