## Description
|
|
<section id='description'>
|
|
The <code>@if</code> directive in Sass is useful to test for a specific case - it works just like the <code>if</code> statement in JavaScript</code>.
|
|
<blockquote>@mixin make-bold($bool) {<br> @if $bool == true {<br> font-weight: bold;<br> }<br>}</blockquote>
|
|
And just like in JavaScript, <code>@else if</code> and <code>@else</code> test for more conditions:
|
|
<blockquote>@mixin text-effect($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'>
|
|
Create a <code>mixin</code> called <code>border-stroke</code> that takes a parameter <code>$val</code>. The <code>mixin</code> should check for the following conditions using <code>@if</code>, <code>@else if</code>, and <code>@else</code>:
|
|
<blockquote>light - 1px solid black<br>medium - 3px solid black<br>heavy - 6px solid black</blockquote>
|
|
If <code>$val</code> is not <code>light</code>, <code>medium</code>, or <code>heavy</code>, the border should be set to <code>none</code>.
