Responsive CSS frameworks take a lot of work and persistence to build and create when building CSS on HTML responsiveness, accessibility, and structure. This is why CSS frameworks were created, to take the stress off of you!
A CSS framework is a software framework created to allow for easier, more standards-compliant web design using HTML/CSS. Many popular CSS frameworks are design-oriented and contain elements that can be re-used in the creation of any website or app, as well as a grid system designed to provide a responsive CSS layout to webpages.
All the frameworks listed in this article are free and open source.
Without a doubt, Bootstrap is the most widely used free and open source CSS framework. Created in 2011 by developers Mark Otto and Jacob Thornton, Bootstrap is now used by millions of websites. Bootstrap features Sass variables and mixins, a responsive grid system, extensive prebuilt components for building layouts, and powerful plugins built on jQuery.
Tailwind is a relatively new CSS framework, designed to be different from its competitors. Instead of predesigned components, Tailwind provides low-level utility classes that let you build your own designs. I personally have used Tailwind in my projects and loved it so far. Let’s have a quick look to some HTML used with Tailwind:
<button class="bg-blue hover:bg-blue-dark text-white font-bold py-2 px-4 rounded"> Button </button>
As you can see, the example is using many utility classes on a button element. Those classes allow you to finely style any element: We can easily spot classes named text-white, font-bold and rounded, defining the visual aspect of the button.
With 21kB minified and gzipped, Bulma isn’t the most lightweight of this list, but this open source CSS framework is so interesting that it totally deserves a mention. Bulma is built with a mobile-first approach, which makes every element optimized for vertical reading, and its grid system is fully built with Flexbox. Achieving flexible layout with same-size columns is as simple as adding a .column class to any of your HTML elements.
Bulma is also built with Sass, which allows you to only use the features you really need in your web development tasks.
