10. What is SCSS and what are its main features?

SCSS (Sassy CSS) is a CSS preprocessor that allows for the use of more advanced features than standard CSS. The main features of SCSS include:

  • Variables: allow storing values (e.g., colors, sizes) and using them throughout the stylesheet.
  • Nested selectors: enable nesting selectors in a way that mirrors the HTML structure, improving code readability.
  • Mixins: allow creating reusable chunks of code.
  • Inheritance: enables inheriting styles from one selector to another.
  • File imports: allow splitting code into smaller, more manageable files.
/* Examples */ $primary-color: #333; /* Variable */ body { font: 100% $primary-color; /* Using variable */ } nav { ul { margin: 0; padding: 0; list-style: none; li { display: inline-block; a { text-decoration: none; } } } } @mixin border-radius($radius) { -webkit-border-radius: $radius; -moz-border-radius: $radius; -ms-border-radius: $radius; border-radius: $radius; } .box { @include border-radius(10px); /* Using mixin */ }
