Modular architecture breaks styles into smaller files or components. This makes it easier to find, update, and reuse code, which is very helpful as projects get bigger.
$primary-color: #3498db; .button { background-color: $primary-color; &:hover { background-color: darken($primary-color, 10%); } }
The Sass variable $primary-color is replaced with its hex value. The nested &:hover becomes .button:hover. The darken function reduces brightness by 10%, resulting in #2a80b9.
.menu { > li { color: red; } }
The selector .menu > li targets only li elements that are direct children of .menu. Other options select descendants or siblings.
Sass variables let you store values like breakpoints or spacing once. When you update a variable, all related styles update, making responsive design easier to maintain.
Using semantic color variables helps maintain consistent colors and makes it easier to update colors project-wide. Checking contrast during development ensures accessibility before release.
