样式第一 table 由 td classname 标识的组行与另一行同级
Style first table row of group identified by td classname sibling to another row
如何更改靠近兄弟行(由 td 标识)的一组行(由带有子项 class 的 td 标识)的第一行的样式与项目 class):
HTML:
<table>
<thead>
</thead>
<tbody>
<tr>
<td class="item"></td>
</tr>
<tr>
<td class="sub-item"><!-- I need to style this one --></td>
</tr>
<tr>
<td class="sub-item"></td>
</tr>
<tr>
<td class="sub-item"></td>
</tr>
<tr>
<td class="item"></td>
</tr>
<tr>
<td class="sub-item"><!-- I need to style this one --></td>
</tr>
</tbody>
</table>
我想用一个内嵌框来设置样式-阴影符合此条件的所有第一行。
我试过兄弟运算符没有成功:
CSS:
tr > td.item ~ tr > td.sub-item:first {}
使用当前代码,您必须使用 :nth-[last]-child()
tr:first-child + tr .sub-item, tr:nth-last-child(2) + tr .sub-item {
background-color: red
}
<table>
<thead>
</thead>
<tbody>
<tr>
<td class="item">1</td>
</tr>
<tr>
<td class="sub-item">2<!-- I need to style this one --></td>
</tr>
<tr>
<td class="sub-item">3</td>
</tr>
<tr>
<td class="sub-item">4</td>
</tr>
<tr>
<td class="item">5</td>
</tr>
<tr>
<td class="sub-item">6<!-- I need to style this one --></td>
</tr>
</tbody>
</table>
此外,您可以在 tr
中添加一个 class 并实现您想要的效果。
.row + tr .sub-item {
background-color: red
}
<table>
<thead>
</thead>
<tbody>
<tr class="row">
<td class="item">1</td>
</tr>
<tr>
<td class="sub-item">2<!-- I need to style this one --></td>
</tr>
<tr>
<td class="sub-item">3</td>
</tr>
<tr>
<td class="sub-item">4</td>
</tr>
<tr class="row">
<td class="item">5</td>
</tr>
<tr>
<td class="sub-item">6<!-- I need to style this one --></td>
</tr>
</tbody>
</table>
