[html] How can I show three columns per row?

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.

The answer is


Try this one using Grid Layout:

_x000D_
_x000D_
.grid-container {_x000D_
  display: grid;_x000D_
  grid-template-columns: auto auto auto;_x000D_
  padding: 10px;_x000D_
}_x000D_
.grid-item {_x000D_
  background-color: rgba(255, 255, 255, 0.8);_x000D_
  border: 1px solid rgba(0, 0, 0, 0.8);_x000D_
  padding: 20px;_x000D_
  font-size: 30px;_x000D_
  text-align: center;_x000D_
}
_x000D_
<div class="grid-container">_x000D_
  <div class="grid-item">1</div>_x000D_
  <div class="grid-item">2</div>_x000D_
  <div class="grid-item">3</div>  _x000D_
  <div class="grid-item">4</div>_x000D_
  <div class="grid-item">5</div>_x000D_
  <div class="grid-item">6</div>  _x000D_
  <div class="grid-item">7</div>_x000D_
  <div class="grid-item">8</div>_x000D_
  <div class="grid-item">9</div>  _x000D_
</div>
_x000D_
_x000D_
_x000D_


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:

_x000D_
_x000D_
.flex-row-container {_x000D_
    background: #aaa;_x000D_
    display: flex;_x000D_
    flex-wrap: wrap;_x000D_
    align-items: center;_x000D_
    justify-content: center;_x000D_
}_x000D_
.flex-row-container > .flex-row-item {_x000D_
    flex: 1 1 30%; /*grow | shrink | basis */_x000D_
    height: 100px;_x000D_
}_x000D_
_x000D_
.flex-row-item {_x000D_
  background-color: #fff4e6;_x000D_
  border: 1px solid #f76707;_x000D_
}
_x000D_
<div class="flex-row-container">_x000D_
  <div class="flex-row-item">1</div>_x000D_
  <div class="flex-row-item">2</div>_x000D_
  <div class="flex-row-item">3</div>_x000D_
  <div class="flex-row-item">4</div>_x000D_
  <div class="flex-row-item">5</div>_x000D_
  <div class="flex-row-item">6</div>_x000D_
</div>
_x000D_
_x000D_
_x000D_

Hope this helps someone else.
