Its a simple answer but says it's wrong why?

Tell us what’s happening:

Your code so far

  .container {
    font-size: 40px;
    width: 100%;
    background: LightGray;
    display: grid;
    /* add your code below this line */
    grid-template-columns: 100px;100px   100px;
    /* add your code above this line */
<div class="container">
  <div class="d1">1</div>
  <div class="d2">2</div>
  <div class="d3">3</div>
  <div class="d4">4</div>
  <div class="d5">5</div>

Link to the challenge:

You only should have one semi-colon and it should be at the end of the three 100px. Remember, CSS property/value pairs are separated by semi-colons, so when you put a semi-colon after the first 100px, then the rest of the line is treated as if it was another property instead of part of the same grid-template-columns property. Also, make sure to use a space to separate the three values.

Thanks knew it was a simple mistake.:grinning:
