How can I show three columns per row?

Question

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

My current CSS is something like this:

.mainDiv {     display: flex;     margin-left: 221px;     margin-top: 43px; } 

This code puts all content in a single row. I want to add a constraint to just shows three records per row.

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>

Answer 2

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.
