À propos de Sass
It is one of the most popular preprocessors currently in use. Sass provides a syntax that allows greater functionality and ease of use to CSS. In contrast to CSS, it is object-oriented and allows nesting, variables, and mixins. Additionally, it allows properties to be defined outside of Sass objects.
All the formatting remains the same as in CSS. Therefore, it is easy to start using Sass as it can be learned very quickly.
