Ive been stuck on this for 9 hours,Please someone tell me why its not working.

<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>

Place the area template so that the cell labeled advert becomes an empty cell.

There is indeed a bug. Thanks for posting about it. I saw on github that there are already people working on it.

To work around the bug, just remove these comments:

    /* Only change code below this line */

    /* Only change code above this line */
