Tell us what’s happening:

I am try in the Firefox and Chrome
in browser inspector (F12) all oOK, but tests fail!

What is wrong?

Also, I try { font-size:5*$x+px;}

Your code so far

<style type='text/sass'>
 $x: 1;
@while $x < 11 {
  .text-#{$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>

Link to the challenge:

Try refreshing the page and running the tests again. If that does not work, make sure you are using Chrome.

Thank you for answer!
I do this, but, unfortunately, no result.
Chrome 67.0.3396.99 (Official build), (64 bit)

If you are using Chrome, try Ctrl+F5.

Solved, I made on another computer.

PS, Ctrl + F5 did not fix the problem

I moved to another computer to pass as well. I left a comment with my details on this thread.
