Comparing SASS with plain CSS

Comparing SASS with plain CSS

October 31, 2025

Why SASS? Syntactically Awesome Style Sheets is a preprocessor scripting language that extends the capabilities of CSS. It provides a range of additional features and functionality that ease the development process and make stylesheets more maintainable.

Pros

  1. Sass allows developers to define variables to store values which can increase maintainability and decrease repetition.

  2. Sass allows developers to nest selectors within one another.

  3. Sass allows creation of mixins with arguments which help in avoiding repeating styles.

Cons

  1. Sass files use the .sass or .scss extension and must be compiled into CSS before they can be used in a web project.

Why CSS? Cascading Style Sheets is a stylesheet language used to define the presentation and formatting of a document written in HTML. CSS has basic features of style sheets.

Pros

  1. CSS follows a plain-text syntax.

  2. CSS can be interpreted by any web browser.

Cons

  1. CSS requires you to write each selector separately.

  2. CSS does not provide functionality to use Mixins and does not use additional features.

Final Verdict This is what I think after learning CSS and SASS: They both have a relation like a roof and the stars. Without CSS, Sass is nothing and without Sass, CSS is too much repetitive and lacks a lot of additional features. Sass is better than using plain CSS because it makes it a lot easier to make new styles and use them again and again without defining new selectors each time.
