🆚 Bootstrap vs. Foundation

Bootstrap is an open-source framework for building responsive, mobile-first websites and web applications with HTML, CSS, and JavaScript, originally developed at Twitter.

It provides a responsive grid system, prebuilt components, extensive Sass variables and mixins, official icon library, and built-in form validation.

Foundation is an open-source responsive framework that provides a customizable grid system, a library of UI components (Building Blocks), HTML templates, and JavaScript plugins.

It includes keyboard accessibility, screen-reader support, ARIA attributes, device-adaptive visibility controls, and two types of grids (Flexbox and CSS Grid) to enable advanced layout control.
