## Description
|
||
|
|
<section id='description'>
|
||
|
|
La directiva <code>@if</code> en Sass es útil para probar un caso específico: funciona igual que la sentencia <code>if</code> en JavaScript.
|
||
|
|
<blockquote>@mixin make-bold($bool) {<br> @if $bool == true {<br> font-weight: bold;<br> }<br>}</blockquote>
|
||
|
|
Y al igual que en JavaScript, <code>@else if</code> y <code>@else</code> prueban para más condiciones:
|
||
|
|
<blockquote>@mixin text-effect($val) {<br> @if $val == danger {<br> color: red;<br> }<br> @else if $val == alert {<br> color: yellow;<br> }<br> @else if $val == success {<br> color: green;<br> }<br> @else {<br> color: black;<br> }<br>}</blockquote>

## Instructions
|
||
|
|
<section id='instructions'>
|
||
|
|
Crea un <code>mixin</code> llamado <code>border-stroke</code> que toma un parámetro <code>$val</code> . La <code>mixin</code> debe verificar las siguientes condiciones usando <code>@if</code> , <code>@else if</code> , y <code>@else</code> :
|
||
|
|
<blockquote>light - 1px solid black<br>medium - 3px solid black<br>heavy - 6px solid black<br>none - no border</blockquote>
