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.

--instructions--

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!

--hints--

Your code should use the @while directive.

assert(code.match(/@while /g));

Your code should use an index variable which starts at an index of 1.

assert(code.match(/\$.*:\s*?1;/gi));

Your code should increment the counter variable.

assert(code.match(/\$(.*)\s*?:\s*\$\1\s*\+\s*1\s*;/gi));

Your .text-1 class should have a font-size of 15px.

assert($('.text-1').css('font-size') == '15px');

Your .text-2 class should have a font-size of 30px.

assert($('.text-2').css('font-size') == '30px');

Your .text-3 class should have a font-size of 45px.

assert($('.text-3').css('font-size') == '45px');

Your .text-4 class should have a font-size of 60px.

assert($('.text-4').css('font-size') == '60px');

Your .text-5 class should have a font-size of 75px.

assert($('.text-5').css('font-size') == '75px');
