Grid repeat to stop repetitions

Tell us what’s happening:
I can’t come up with the code no matter what I put in there and I’ve been looking it up and can’t seem to find any help on this using repeat to stop repetitions!!??

Your code so far


.container {
  font-size: 40px;
  min-height: 300px;
  width: 100%;
  background: LightGray;
  display: grid;
  /* Only change code below this line */
  grid-template-columns: repeat();

  /* Only change code above this line */
  grid-template-rows: 1fr 1fr 1fr;
  grid-gap: 10px;

<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>

Challenge: Reduce Repetition Using the repeat Function

Link to the challenge:

So you have to look at what was there originally first.
grid-template-columns: 1fr 1fr 1fr;

What is/are the values here?

How many times is it repeated?

The format for repeat() is repeat(#_of_repeats, value_to_repeat)
