Please i’m finding it difficult to understand this.

Your code so far

  .item2{background:LightSalmon;}
  .item3{background:PaleTurquoise;}
  .item4{background:LightPink;}
  
  .item5 {
    background: PaleGreen;
    /* add your code below this line */
    grid-column: 2 / 4;
    
    /* add your code above this line */
  }
  
  .container {
    font-size: 40px;
    min-height: 300px;
    width: 100%;
    background: LightGray;
    display: grid;
    grid-template-columns: 1fr 1fr 1fr;

Could you be more specific? Which part do you find difficult to understand?

It sets the start and end column of the grid item. I think the most important concept to understand here is the grid lines. In a three column layout, as given by the challenge, the first line is 1 and the last line is 4.

Here is the MDN docs for grid-column. Here is a guide article on using Line-based placement with CSS Grid.
