what is bootstrap-sass fr?

Bootstrap is a popular toolkit for building the visual look of websites, providing pre-made styles for buttons, forms, navigation bars, and other common elements. This repository is the official Sass port of Bootstrap 3, meaning it translates Bootstrap's styling code into a format that works with the Sass stylesheet language. Sass is an extension of regular CSS that adds features like variables, nesting, and reusable style chunks. The main reason to use this version over plain Bootstrap is that Sass lets you customize Bootstrap's colors, sizes, and behavior by changing variables before the styles are compiled, rather than overriding styles after the fact. You can also pick and choose which parts of Bootstrap you want to include, keeping your final stylesheet smaller. This package works with several popular installation methods. Ruby on Rails developers can add it as a gem to their project. Node.js developers can install it through npm. It is also available via Bower. The README provides detailed setup instructions for each of these paths, including how to import the styles and load the JavaScript components correctly. It is worth noting that this repository covers Bootstrap version 3 only. Bootstrap 4 and later versions handle Sass support differently and are maintained in separate repositories. This project is essentially an older, stable release kept available for projects that still rely on Bootstrap 3.
