CSS Clear after every nth-child

Question

I have multiple items with same width inside a container. Because of different heights of the elements, there is problem with the alignment, you can see in image below.

Answer 1

You can use:

.list {
  display:flex;
  flex-wrap: wrap;
  ...
}

See below:

.list {
  width: 300px;
  overflow: hidden;
  display: flex;
  flex-wrap: wrap;
}
.item {
  float: left;
  width: 90px;
  background: yellow;
  margin-right: 5px;
  margin-bottom: 10px;
}
.item:nth-child(3) {
  background: brown;
}
.item:nth-child(3):after {
  content: ".";
  display: block;
  height: 0;
  clear: both;
  visibility: hidden;
}
