表格行上的 CSS 框阴影未正确显示

Hau*_*aus 3 css box-shadow

当鼠标悬停在表格行上时,我在表格行上添加了一个轻微的框阴影,以便它更加明显。它按预期工作,但是当我添加交替行颜色时,它停止正确显示。

这是问题的 JSFiddle。

<div class="search-table">
<table>
  <tbody>
    <tr>
      <td>A1</td>
      <td>A2</td>
    </tr>
    <tr class="alt">
      <td>B1</td>
      <td>B2</td>
    </tr>
    <tr>
      <td>C1</td>
      <td>C2</td>
    </tr>
    <tr class="alt">
      <td>C1</td>
      <td>C2</td>
    </tr>
  </tbody>
</table>

正如您所看到的,当鼠标悬停在具有“alt”类的深色行上方时,框阴影会按预期显示,但对于浅色行,它仅在行的顶部显示阴影,而不是在底部显示阴影。从第二行和第四行中删除“alt”类可以修复此问题,但代价是交替行颜色。是什么导致了这种行为的发生,我该如何解决它?

transform: scale(1)您可以通过应用于悬停行来修复框阴影被其他表行“隐藏”的问题:

.search-table table tbody tr:hover {
    box-shadow: 0px 0px 3px 0px #00000082;
    transform: scale(1);
}
