Using multiple conditions (AND) in SASS IF statement

Question

Using SASS, I would like to have multiple condition in IF statement

What I use right now :

@function color-x ($alpha) {     @if      $accent == red   {@return red($alpha)}      @else if $accent == green {@return green($alpha)}      @else if $accent == blue  {@return blue($alpha)} } 

My naive (failed) attempt to use multiple conditions :

@function color-x ($alpha) {     @if      $accent == red   && theme == light {@return red($alpha)}      @else if $accent == green && theme == light {@return green($alpha)}      @else if $accent == blue  && theme == light {@return blue($alpha)} } 

Is it possible to have multiple conditions?

Answer 1

From the Sass language reference documentation:

Boolean Operations

SassScript supports and, or, and not operators for boolean values.

(link)

So an if statement expression with a compound condition would look like this:

@if $var1 == value1 and $var2 == value2 {     // ... } 

Further, parentheses can be used to affect the order of operations in a more complicated expression:

@if ($var1 == value1 and not ($var2 == value2)) or ($var3 == value3) {     // ... }
