.nav {
ul {
list-style: none;
}
li {
display: inline-block;
}
}
Mixins: Create reusable style blocks.
@mixin border-radius($radius) {
border-radius: $radius;
}
.box {
@include border-radius(10px);
}
Functions: Define custom functions for more complex calculations.
@function calculate-rem($pixels) {
@return $pixels / 16 * 1rem;
}
.text {
font-size: calculate-rem(24px);
}
