CSS: Rendering 4 items in 2 columns using Columns: 3

Question

I want to create a 3 column masonry layout to render items with the same width but different heights, but when I try the code below, I see that the third column is empty, which looks a little weird. Can I fix it somehow?

I tried this code, I want to have two items in the first column and one item in the second and third columns. Please note that 4 items of the same height is just a specific case, ultimately I don't know how many items there will be and the height of each item.

.container {
  column-count: 3;
  background-color: #f7f7f7;
  width: 588px
}

.item {
  width: 180px;
  height: 180px;
  break-inside: avoid;
  background-color: #e5e5e5;
  margin-bottom: 20px;
}

<div class="container">
  <div class="item">
    1
  </div>
  <div class="item">
    2
  </div>
  <div class="item">
    3
  </div>
  <div class="item">
    4
  </div>
</div>

For this case, you can combine display: flex with flex-wrap: wrap and justify-content: space- Between using containers

.container {
  display: flex;
  flex-wrap: wrap;
  justify-content: space-between;
  background-color: #f7f7f7;
  width: 588px
}

.item {
  width: 180px;
  height: 180px;
  break-inside: avoid;
  background-color: #e5e5e5;
  margin-bottom: 20px;
}
