最佳答案

This may be what you are looking for:

body>div {
background: #aaa;
display: flex;
flex-wrap: wrap;
}


body>div>div {
flex-grow: 1;
width: 33%;
height: 100px;
}


body>div>div:nth-child(even) {
background: #23a;
}


body>div>div:nth-child(odd) {
background: #49b;
}

<div>
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
</div>

Even though the above answer appears to be correct, I wanted to add a (hopefully) more readable example that also stays in 3 columns form at different widths:

.flex-row-container {
background: #aaa;
display: flex;
flex-wrap: wrap;
align-items: center;
justify-content: center;
}
.flex-row-container > .flex-row-item {
flex: 1 1 30%; /*grow | shrink | basis */
height: 100px;
}


.flex-row-item {
background-color: #fff4e6;
border: 1px solid #f76707;
}

<div class="flex-row-container">
<div class="flex-row-item">1</div>
<div class="flex-row-item">2</div>
<div class="flex-row-item">3</div>
<div class="flex-row-item">4</div>
<div class="flex-row-item">5</div>
<div class="flex-row-item">6</div>
</div>

Hope this helps someone else.

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;
}

<div class="grid-container">
<div class="grid-item">1</div>
<div class="grid-item">2</div>
<div class="grid-item">3</div>
<div class="grid-item">4</div>
<div class="grid-item">5</div>
<div class="grid-item">6</div>
<div class="grid-item">7</div>
<div class="grid-item">8</div>
<div class="grid-item">9</div>
</div>

You can now use grid-auto-flow

https://jsfiddle.net/chalcrow/bqye79kr/1/

CSS

.grid-flow {
display: grid;
grid-auto-flow: row;
grid-template-columns: repeat(3, 1fr);
grid-template-rows: repeat(2, 1fr);
}

Note - the repeat(3, 1fr) means '3 columns, each taking up 1 (equal) fraction of the available space.

HTML

<div class="grid-flow">
<div>1</div>
<div>2</div>
<div>3</div>
<div>4</div>
<div>5</div>
<div>6</div>
</div>
