Can someone explain it better?

Tell us what’s happening:

Your code so far

  .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;
    /* change code below this line */
      "header header header"
      "advert content content"
      "footer footer footer";
    /* change code above this line */
<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>

Just go to challenges i don’t understand it.

Are you not understanding what the instructions ask you to do or do you just not understand how to write the correct code?

Take a look at the following post where I helped someone else with this challenge.

Yes, zero, the more specific your question, the easier it is to help you. There are no dumb questions, but we still need a question. We can’t start at the beginning of web development and work our way up until we find the problem.
