尝试配置表以使所有偶数行具有相同的颜色，我将“tr nth-child”设置为#CCC，但不管怎样，选择行而不是选择行。这是我的代码：
tr :nth-child:{
background:#CCC
}
<table class="fold-table table" align="center">
<thead>
<tr style="background: #1b4156; color: #FFFFFF; border-bottom: 1px; border-bottom-color: #000000">
<th>Data</th>
<th>Able to post this </th>
<th>Frequency</th>
<th>Access</th>
</tr>

我已经检查了各种类似的问题，但找不到适用于我所遇到的这个问题...所有指针都将非常感激
答案 0 :(得分：1)
您必须指定 nth-child
tr:nth-child(3) {
background: #CCC
}
对于备用行，您可以使用
tr:nth-child(odd|even) {
background: #CCC
}
答案 1 :(得分：0)
语法错误：nth-child。它应该是：nth-child（n），其中n表示第n个孩子。 以下是示例代码：
tr:nth-child(3)
{background:#CCC;}<table class="fold-table table" align="center">
<thead>
<tr style="background: #1b4156; color: #FFFFFF; border-bottom: 1px; border-bottom-color: #000000">

答案 2 :(得分：0)
对于偶数行，您可以尝试
tr:nth-child(even) {
background: #CCC
}
您还可以通过给出子值（n）来为n：th child选择行：1,2,3
tr:nth-child(n) {
background: #CCC
}
