How can I show three columns per row?

I have been trying to show three columns per row. Is it possible using flexbox?

My current CSS is something like this:

Try this one using Grid Layout:

.grid-container {
  display: grid;
  grid-template-columns: auto auto auto;
  padding: 10px;
}
.grid-item {
  background-color: rgba(255, 255, 255, 0.8);
  border: 1px solid rgba(0, 0, 0, 0.8);
  padding: 20px;
  font-size: 30px;
  text-align: center;
}
