Flexbox: 4 items per row

Question

I\'m using a flex box to display 8 items that will dynamically resize with my page. How do I force it to split the items into two rows? (4 per row)?

Here is a releva

Answer 1

Add a width to the .child elements. I personally would use percentages on the margin-left if you want to have it always 4 per row.

DEMO

.child {
    display: inline-block;
    background: blue;
    margin: 10px 0 0 2%;
    flex-grow: 1;
    height: 100px;
    width: calc(100% * (1/4) - 10px - 1px);
}
