The pre-processor Sass helps with what?

Sass, or Syntactically Awesome Style Sheets, is a pre-processor that extends CSS with features that make it easier to write and maintain stylesheets. It introduces capabilities such as variables, nesting, mixins, inheritance, and functions, which allow developers to create more organized and reusable CSS code. This leads to better maintainability of stylesheets, as it can reduce redundancy and make the overall structure cleaner.

While Sass focuses on stylesheets, it does not directly enhance JavaScript queries, generate HTML elements, or optimize image sizes. The other options revolve around different aspects of web development that Sass is not intended to address, highlighting its specific role in managing and improving CSS.
