Bug on Apply a Style Until a Condition is Met with @while

Tell us what’s happening:
I put the code, it works on the preview but doesn’t pass tests

Your code so far

<style type='text/sass'>
$x: 1;
@while $x <= 10 {
    .text-#{$x}{font-size: 5px * $x;}
    $x: $x + 1;

<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>
<p class="text-6">Hello</p>
<p class="text-7">Hello</p>
<p class="text-8">Hello</p>
<p class="text-9">Hello</p>
