我一直试图每行显示三列。是否可以使用flexbox?
我目前的CSS是这样的:
.mainDiv {
display: flex;
margin-left: 221px;
margin-top: 43px;
}
此代码将所有内容放在一行中。 我想添加一个约束来显示每行三个记录。

这可能是您正在寻找的:
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>

尽管以上答案似乎是正确的,但我还是想添加一个(希望)更具可读性的示例,该示例也以3列的形式保留在不同的宽度上:
.flex-row-container {
background: #aaa;
display: flex;
flex-wrap: wrap;
align-items: center;
justify-content: center;
}
.flex-row-container > .flex-row-item {
flex-grow: 1;
flex: 1 1 30%;
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>
希望这对其他人有帮助。

使用“网格布局”尝试这一操作:
.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>
