Grid column to control spacing

Tell us what’s happening:

I didn’t understand what does this 1/3 or 2/4 do to these columns and rows and what are they specifying?

Your code so far


.item5 {
  background: PaleGreen;
  /* Only change code below this line */

grid-column: 2 / 4;
  /* Only change code above this line */

.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;

<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: Use grid-column to Control Spacing

Link to the challenge:

Hello @kkjvasai,
Let’s look back at the image the challenge provided
This shows how the grid columns and row works. So what you are doing is instructing the boxes to start from a certain grid and then end at another grid.

element {
/* Here I asked the element to stop stretching on grid 4 */
  grid-column: 2/4;
/* Here i asked the element to start stretching from grid 2 */
