Tell us what’s happening:
Describe your issue in detail here.

  **Your code so far**

.container {
  font-size: 1.5em;
  min-height: 300px;
  width: 100%;
  background: LightGray;
  display: grid;
  grid-template-columns: auto 1fr;
  grid-template-rows: auto 1fr auto;
  grid-gap: 10px;

  grid-area: header;

.item2 {
  background: LightSalmon;
  grid-area: advert;

.item3 {
  background: PaleTurquoise;
  grid-area: content;
  grid-template-columns: auto, (1fr);
  display: grid;
  /* Only change code below this line */

  /* Only change code above this line */

.item4 {
  background: lightpink;
  grid-area: footer;

.itemOne {
  background: PaleGreen;

.itemTwo {
  background: BlanchedAlmond;

Challenge: Create Grids within Grids

Link to the challenge:

Possibly the instructions were not clear as to the format of the code you were to enter. But if you look in the .container class you will see an example.
Compare yours to code that works and you’ll see the difference.

On a side note, there are comments that tell you where to place your code. You didn’t not place your code correctly.
Although it will not cause this test to fail there are later lessons where placing your code correctly is a must.
