【问题描述】：

我正在尝试在悬停时更改表格行的颜色。通过使用行：悬停，但通过这种方式，它只是悬停在一个明显的特定单元格上。但是当我尝试使用row cell: hover 时，它没有任何效果。这是我的html。

 <div id="table">
  <div class="header-row row">
<span class="cell">SI. No.</span>
    <span class="cell">Application Date</span>
    <span class="cell">Customer Name</span>
    <span class="cell">Loan Amount</span>
    <span class="cell">Loan Status</span>
    <span class="cell">Action</span>
  </div>
<div class="row" *ngFor="let item of customerList ; let i= index;">
    <input type="radio" name="expand">
<span class="cell" data-label="SI. No.">{{i+1}}</span>
<span class="cell" data-label="Application Date">{{item.date}}</span>
<span class="cell" data-label="Customer Name">
  {{item.name}}</span>
<span class="cell" data-label="Loan Amount">{{item.amount}}</span>
<span class="cell" data-label="Loan Status">{{item.status}}</span>

去掉.row和:hover之间的空格，给出如下样式。

.row:hover {
    background: green;
}

只需添加 !important 关键字即可。

  .row :hover {
    background: green !important;
  }
