Sass (Syntactically Awesome Style Sheets) is a CSS preprocessor that extends the capabilities of CSS. It allows to write more organized and maintainable stylesheets by introducing variables, mixins, nesting, and other powerful features.
The Sass files in Bootstrap provide a modular and flexible approach to customizing the framework. They allow to override default variables, and extend the existing styles to tailor Bootstrap’s appearance and behavior to your needs.
Variables
When using Bootstrap with Sass, you can access a set of Sass variables that allow you to customize various aspects of the framework. These variables are defined in Bootstrap’s _variables. scss file, which you can modify to suit your project’s needs.
Bootstrap allows you to leverage most of the element, like the accordions, buttons or cards, making it easier to manage and maintain your stylesheets Additionally, Sass allows you to organize your CSS code more effectively and reuse styles across your project.
