Answer 1

Check this:

.container {
  display: grid;
  grid-template-columns: repeat(2, 1fr);
  grid-template-rows: repeat(4, 1fr);
  grid-column-gap: 10px;
  grid-row-gap: 10px;
}

.item {
  border: 1px gray solid;
  color: white;
  padding: 20px;
  text-align: center;
}

.item1 {
  grid-area: 1 / 1 / 2 / 2;
  background: red;
}
.item2 {
  grid-area: 1 / 2 / 2 / 3;
  background: green;
}
.item3 {
  grid-area: 2 / 1 / 4 / 3;
  background: blue;
}
.item4 {
  grid-area: 4 / 1 / 5 / 2;
  background: brown;
}

<div class="container">
  <div class="item item1">
    1
  </div>
  <div class="item item2">
    2
  </div>
  <div class="item item3">
    3-6
  </div>
  <div class="item item4">
    7
  </div>
</div>
