CSS Grid Problem Not Accepting Solution

Tell us what’s happening:
The problem asks to make the “advert” cell an empty cell, so I replaced it with a period as the prompt said to do. I have not changed anything else in the code, and have tried resetting it multiple times. I used the hint button to check the solution, and as far as I can tell my solution is exactly the same as theirs, yet I still get the “X” when I run tests and it will not let me continue.

EDIT: For some reason, deleting the comments allowed me to continue. I do think this is a bug that needs to be fixed.

Your code so far


<style>
.item1{background:LightSkyBlue;}
.item2{background:LightSalmon;}
.item3{background:PaleTurquoise;}
.item4{background:LightPink;}
.item5{background:PaleGreen;}

.container {
  font-size: 40px;
  min-height: 300px;
  width: 100%;
  background: LightGray;
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
  grid-template-rows: 1fr 1fr 1fr;
  grid-gap: 10px;
  grid-template-areas:
  /* Only change code below this line */
  "header header header"
  ". content content"
  "footer footer footer";
  /* Only change code above this line */
}
</style>

<div class="container">
<div class="item1">1</div>
<div class="item2">2</div>
<div class="item3">3</div>
<div class="item4">4</div>
<div class="item5">5</div>
</div>

It’s a known bug (will be fixed). If you remove the top comment you should pass.

Edit: Didn’t see your edit, sorry. Anyway, it’s getting fixed.
