How to force a flex box to display 4 items per row

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 relevant snip:

(Or if you prefer jsfiddle - http://jsfiddle.net/vivmaha/oq6prk1p/2/)



.parent-wrapper {
height: 100%;
width: 100%;
border: 1px solid black;
}
.parent {
display: flex;
font-size: 0;
flex-wrap: wrap;
margin: -10px 0 0 -10px;
}
.child {
display: inline-block;
background: blue;
margin: 10px 0 0 10px;
flex-grow: 1;
height: 100px;
}

<body>
<div class="parent-wrapper">
<div class="parent">
<div class="child"></div>
<div class="child"></div>
<div class="child"></div>
<div class="child"></div>
<div class="child"></div>
<div class="child"></div>
<div class="child"></div>
<div class="child"></div>
</div>
</div>
</body>




Answer

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);
}

Edit: OP answered his the width problem by using calc();
