网格列未使用完整 space 行，溢出到下一行
grid columns not using full space of rows, overflowing to next line
我正在制作卡片（图片）的布局，希望它们大小相同。
我想要每行 4 列，每列一张卡片。然后我的下一行还有4个，依此类推。
我的卡片没有占据每一行的 4 列，而是只占用了 3 列，然后第 4 张卡片溢出了。

您正在将 margin: .5em; 应用到 .card，这也是 .col-md-3 摆脱了网格间距。如果您需要该边距，请将 .cards 嵌套在 .col-*s 中：
<div class="container">
<div class="row">
<div style="justify-content: center" class="col-md-3">
<div class="card">
<img />
....
</div>
</div>
<div style="justify-content: center" class="col-md-3">
<div class="card">

....
</div>
</div>
....
</div>
</div>
我将 col-12 添加到您的 HTML 并在 CSS 上进行了灵活显示。从这里开始，我建议让您的父容器变大或减少一些边距或填充。
