Just a few hours ago I noticed a notification from Bootstrap’s Twitter account letting me know that Bootstrap 5 alpha version has been officially released. Here’s the official page and documentation for Bootstrap 5.
So what’s different about the new version? Well first of all let me tell you that I absolutely love the new logo and the idea behind it. According to the developers behind the framework this is how they got inspired:
“Inspired by the CSS that created the very beginnings of this project, our logo embodies the feeling of a rule set—style bounded by curly braces. We love it and think you will, too. Expect to see it roll out to v4’s documentation, our blog, and more over time as we continue to refine things and ship new releases.”Bootstrap team
So let’s get to the point. Bootstrap 5 officially drops jQuery and support for Internet Explorer 10 and 11. This comes as a huge leap forward for a lighter codebase and a better outlook for the future. Although some developers who work in enterprise powered projects will look at this as a disadvantage, there are ways to workaround IE support using polyfills.
There are some other exciting new features such as a utilities API, updated forms, an expanded color palette, custom icons and many more. We’ll get into the details for each section in this article.
Because most of jQuery’s features can now be done using vanilla JS, there’s not too much reason to keep it around. We will write a guide in the coming days on how to migrate from Bootstrap 4 to version 5 and replace old jQuery code with updated vanilla JS.
For some developers this may have come as a bigger surprise than removing jQuery as a dependency mostly because there still are many companies and people using these old browsers for enterprise websites.
But don’t worry, there are workarounds using polyfill to make it work, it’s just not supported by default anymore. You can read more about our take on Bootstrap 5 dropping support for IE 10 & 11 in a previous article.
So this is another very welcoming feature. CSS custom properties are native variables for the browser and compared to Sass variables the advantage is that they are, well, native. It will be much easier to update a wide range of CSS properties dynamically.
For instance, dark vs light modes now will no longer need to be changed via another CSS file but through the custom properties. Here’s the default list of root variables for the colors:
--bs-blue: #0d6efd; --bs-indigo: #6610f2; --bs-purple: #6f42c1; --bs-pink: #d63384; --bs-red: #dc3545; --bs-orange: #fd7e14; --bs-yellow: #ffc107; --bs-green: #28a745; --bs-teal: #20c997; --bs-cyan: #17a2b8; --bs-white: #fff; --bs-gray: #6c757d; --bs-gray-dark: #343a40; --bs-primary: #0d6efd; --bs-secondary: #6c757d; --bs-success: #28a745; --bs-info: #17a2b8; --bs-warning: #ffc107; --bs-danger: #dc3545; --bs-light: #f8f9fa; --bs-dark: #343a40; --bs-font-sans-serif: system-ui, -apple-system, "Segoe UI", Roboto, "Helvetica Neue", Arial, "Noto Sans", sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Noto Color Emoji"; --bs-font-monospace: SFMono-Regular, Menlo, Monaco, Consolas, "Liberation Mono", "Courier New", monospace; --bs-gradient: linear-gradient(180deg, rgba(255, 255, 255, 0.15), rgba(255, 255, 255, 0)); }
According to the official blog post the developers behind the framework are saying that they have improved the documentation by giving more explanation, removing ambiguities and by extending the page showing how to customize the framework.
Additionally to the improved docs, we can observe a much more extensive and beautiful color palette with a focus on choosing accessible and well contrasted colors.
I think this is probably the most interesting aspect of Bootstrap 5. It reminds me of how Tailwind CSS works as a utility first CSS Framework and by using the utilities API from Bootstrap you have unlimited possibilities to create utility classes for spacing, positioning, sizing and so on.
For instance, you will be able to easily expand the number of
p-* classes and so on without needing to write custom Sass code to expand them. Here’s an example showing us how the $utilities variable can be expanded by adding multiple values:
$utilities: () !default; $utilities: map-merge( ( // ... "width": ( property: width, class: w, values: ( 25: 25%, 50: 50%, 75: 75%, 100: 100%, auto: auto ) ), // ... "margin": ( responsive: true, property: margin, class: m, values: map-merge($spacers, (auto: auto)) ), // ... ), $utilities);
A few months ago a new exciting set of custom SVG powered icons was launched by the creators of Bootstrap. I appreciate the original look and feel of the icons and surely it is worth a try if you’ve been using older libraries. We also wrote an article comparing Bootstrap 5 with Font Awesome in terms of design, usability and performance.
