What is a CSS Framework?

In order to build a website, there are many tools and frameworks available for web designers and developers. However, choosing the best one amongst the plethora of options available is a daunting task. Having said that, frameworks tend to simplify the process of creating a website. In simple words, a CSS framework is a ready-to-use CSS library. These stylesheets provide a package that consists of the back-end, structured, and standardized scripts like HTML, CSS, or Java. These are referred to as front-end frameworks, which aim to assist users in structuring the pages.

So instead of starting every project from scratch, you can use a CSS framework, that provides you tools to build a user interface quickly and easily. Moreover, these frameworks also help build a more standard-compliant website. Also, you don’t have to redo the code from scratch, every time.

Foundation 6.7 vs Bootstrap 5.3

Both Foundation and Bootstrap have been rigorously updating. These amazing features enhance the entire process and make it smoother. With the latest release in both the designing tools, their features have gotten immensely popular. Let us look at these latest features separately. This, in turn, will lead us to the Bootstrap vs Foundation comparison.

Foundation 6.7.5 Features:

  • Includes XY grids

The latest version of Foundation includes a strong default grid system namely XY grids. This makes you control the layouts displayed both horizontally and vertically.

  • Flexbox by default

Although there is a feature available which allows the fall back to float-mode, Flexbox is what they recommend.

  • Smooth scrollin”

This feature can be used to create “smooth scroll” behavior for any link available inside the page.

  • Shifted to ES2016 JavaScript

Foundation moved its JavaScript architecture to ES2016 module-based architecture. If one does not have module bundler. The drop-in compiled JS files in dist/js will provide backward compatibility.

  • Easier prototyping

The process of prototyping and production often confuses people. With this feature, Foundation offers a better way and a “prototype mode” to speed up the prototyping function.


Bootstrap 5.3 Features:

  • Dark Mode

The core of Bootstrap has been re-written to provide dark mode feature. Also now Bootstrap supports any number of colors. So you can easily build custom themes using more color options.

Why Is Foundation Not As Popular As Bootstrap?

Foundation, focuses on two aspects; providing responsive frameworks for sites and emails. Whereas, Bootstrap had been into Framework designing only and just recently expanded with providing themes. This is again an extension in the same direction. And, it further highlights that Foundation’s efforts were somewhat divergent, unlike Bootstrap. This provides an edge to Bootstrap over Foundation in the Bootstrap vs Foundation combat.

Bootstrap also gets publicity endorsement through Twitter since it was to work exclusively for Twitter. Foundation, on the other hand, remains more of a trade secret. And for novice developers, Bootstrap seems like a piece of cake in front of Foundation. These can be some of the possible reasons behind Bootstrap having a more popular consumer base.

Below is a graphic representation of the both the searches. It is quite evident that both Bootstrap framework and Foundation framework searches are in the zigzag pattern. They are regularly increasing and decreasing, following the same trend. But, bootstrap has double searches meaning double popularity. This affirms its mass hold in the frameworks realm. Thus, helping us with a lot more insight to the issue: Bootstrap vs Foundation.
