Sass / Scss

SaaS/SCSS in CSS to be a valuable addition to your toolkit. These are not to be confused with Software as a Service (SaaS); rather, they are technologies related to Cascading Style Sheets (CSS).

What is SASS/SCSS?​

SASS (Syntactically Awesome Stylesheets) is a preprocessor scripting language that is interpreted or compiled into CSS. SCSS (Sassy CSS) is a syntax of SASS and stands for 'Sassy CSS'. It uses the same syntax as CSS, making it easy to switch from plain CSS to SCSS.

How Do They Work?​

SASS​

SASS uses indentation to separate code blocks and newline characters to separate rules. It provides features like variables, nested rules, mixins, and functions, which are not available in plain CSS.

Example:

$primary-color: blue

.container
  background-color: $primary-color
  .item
    color: white

SCSS​

SCSS is more similar to traditional CSS, using curly braces to denote code blocks and semicolons to separate lines within a block. It also supports all the features of SASS.

Example:

$primary-color: blue;

.container {
  background-color: $primary-color;
  .item {
    color: white;
  }
}

Key Features​

  1. Variables: Store reusable values like colors, font sizes, and margins.

  2. Nesting: Nest CSS selectors within each other, making the stylesheet easier to read and maintain.

  3. Mixins: Reusable blocks of code that can be inserted into any rule set.

  4. Functions: Perform computations and manipulations on variables and values.

  5. Inheritance: Share a set of CSS properties from one selector to another.

  6. Modularization: Divide your code into multiple files and import them into a single file.

Advantages​

  • Maintainability: Easier to maintain and update styles.

  • Reusability: Reuse common styles across different parts of your application.

  • Community Support: Strong community and plenty of frameworks built around it.

  • Compatibility: Compiled into standard CSS, making it compatible with all browsers.

How to Use​

  1. Installation: Install Node.js and use npm to install SASS.

    npm install -g sass

  2. Compilation: Compile your SASS/SCSS files into CSS.

    sass input.scss output.css

  3. Watch Mode: Automatically compile when files change.

    sass --watch input.scss:output.css
