Tell us what’s happening:

When the viewport is 400px or more, container class should have a grid-template-areas property in which the header and footer areas occupy the top and bottom rows respectively and advert and content occupy the left and right columns of the middle row.

Your code so far


<style>
.item1 {
  background: LightSkyBlue;
  grid-area: header;
}

.item2 {
  background: LightSalmon;
  grid-area: advert;
}

.item3 {
  background: PaleTurquoise;
  grid-area: content;
}

.item4 {
  background: lightpink;
  grid-area: footer;
}

.container {
  font-size: 1.5em;
  min-height: 300px;
  width: 100%;
  background: LightGray;
  display: grid;
  grid-template-columns: 1fr;
  grid-template-rows: 50px auto 1fr auto;
  grid-gap: 10px;
  grid-template-areas:
    "header"
    "advert"
    "content"
    "footer";
}

@media (min-width: 300px){
  .container{
    grid-template-columns: auto 1fr;
    grid-template-rows: auto 1fr auto;
    grid-template-areas:
      "advert header"
      "advert content"
      "advert footer";
  }
}

@media (min-width: 400px){
  .container{
    grid-template-areas:
    /* Only change code below this line */
      "advert header"
      "advert content"
      "advert footer";
    /* Only change code above this line */
  }
}
</style>

<div class="container">
<div class="item1">header</div>
<div class="item2">advert</div>
<div class="item3">content</div>
<div class="item4">footer</div>
</div>

Hello!
This is the section of the code you’re tasked with changing. Remember that you’ve set up a grid with 2 columns and 3 rows.
Look at the block of text between the comments - does that look similar to your grid?

#3

do you understand why this part is wrong?

it asks for certain things to occupy the top row or the bottom row completely, but instead you have the advert that is occupying the whole left column
