Description : Using `@if` to conditionally apply styles in SASS.
Answer :
`@if` is used inSASS to apply styles conditionally based on certain criteria. For example, use `@if $theme == light { background-color: white; } @else { background-color: black; }` to set different background colors depending on the value of the `$theme` variable. This feature enhances flexibility by allowing styles to adapt based on dynamic conditions.
