<!-- Apply a Style Until a Condition is Met with @while
The @while directive is an option with similar functionality to the JavaScript while loop. It creates CSS rules until a condition is met.

The @for challenge gave an example to create a simple grid system. This can also work with @while.

$x: 1;
@while $x < 13 {
.col-#{$x} { width: 100%/12 * $x;}
$x: $x + 1;
}
First, define a variable $x and set it to 1. Next, use the @while directive to create the grid system while $x is less than 13. After setting the CSS rule for width, $x is incremented by 1 to avoid an infinite loop.

Use @while to create a series of classes with different font-sizes.

There should be 5 different classes from text-1 to text-5. Then set font-size to 15px multiplied by the current index number. Make sure to avoid an infinite loop!

- Your code should use the @while directive.
- Your code should use an index variable which starts at an index of 1.
- Your code should increment the counter variable.
- Your .text-1 class should have a font-size of 15px.
- Your .text-2 class should have a font-size of 30px.
- Your .text-3 class should have a font-size of 45px.
- Your .text-4 class should have a font-size of 60px.
- Your .text-5 class should have a font-size of 75px.

<style type='text/scss'>

  $x: 1;
  @while $x <= 5 {
    .text-#{$x} {
      font-size: 15px * $x;
    }
    $x: $x + 1;
  }

</style>

<p class="text-1">Hello</p>
<p class="text-2">Hello</p>
<p class="text-3">Hello</p>
<p class="text-4">Hello</p>
<p class="text-5">Hello</p>
