提问by maxspan
I have been trying to show three columns per row. Is it possible using flexbox?
我一直在尝试每行显示三列。是否可以使用 flexbox？
My current CSS is something like this:
我目前的 CSS 是这样的：
.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.
此代码将所有内容放在一行中。我想添加一个约束，每行只显示三个记录。

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:
尽管上面的答案似乎是正确的，但我想添加一个（希望）更具可读性的示例，该示例也以不同宽度的 3 列形式保留：
.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.
希望这对其他人有帮助。

Try this one using Grid Layout:
使用网格布局试试这个：
.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>
