Flexbox item wrap to a new line [duplicate]

Answer 1

This seems to be possible to do with Grid-layout. First to position items inline you can use

grid-template-columns: repeat(auto-fill, 50px);

so that each item takes 50px and it will position items in one line until no more items can fit in one line. And then you can use grid-column-start: 1; on specific item so that it goes to new line.

* {
  box-sizing: border-box;
}
.flex {
  display: grid;
  grid-gap: 10px;
  grid-template-columns: repeat(auto-fill, 50px);
  border: 2px solid red;
}

.item {
  width: 50px;
  height: 50px;
  margin: 5px;
  border: 2px solid blue;
}

.new-string {
  grid-column-start: 1;
  background: red;
}
