Dirisha @if katika SASS

Ikiwa tunahitaji mitindo fulani itumike tu wakati masharti maalum yamefikiwa, basi tunatumia dirisha @if, ambayo hurudisha thamani yoyote, isipokuwa false na null:

Tuchunguze mfano ufuatao:

#main-button {
	@if 2 - 1 == 1 {
		color: green;
	}
	@if (2+3) < 3 {
		color: orange;
	}
	@if null {
		color: red;
	}
}

Matokeo ya ukusanyaji:

#main-button {
	color: green; 
}

Pia, wakati wa kuweka sharti baada ya @if inawezekana kutumia @else if kadhaa na usemi mmoja @else.

$var: 20px;

a {
	@if $var == 10px {
		color: blue;
	} @else if $var == 25px {
		color: red;
	} @else if $var == 10px+10px {
		color: green;
	} @else {
		color: black;
	}
}

Sasa tuangalie kwenye faili styles.css:

a {
	color: green;
}

Eleza, matokeo ya ukusanyaji ya mfumo ufuatao utakuwa nini:

$size: 20px;
$font-size: 14px;

body {
	@if $size == $font-size {
		background-color: #7e7ed8;
	} @else if $size > $font-size {
		color: #f1bbbb;
	} @else {
		color: #000000;
	}
}

Eleza, matokeo ya ukusanyaji ya mfumo ufuatao utakuwa nini:

$size: 20px;
$font-size: 14px;

.active {
	@if $size < $font-size {
		color: red;
	} @else if $size > $font-size {
		color: green;
	} @else {
		color: #000000;
	}
}

.not-active {
	@if $size == $font-size {
		display:block ;
	} @else {
		display: none;
	}
}
