在第一个单元格悬停时覆盖表格单元格

我创建了一个表格列表。当用户悬停第一个包含3个点编辑和删除选项的单元格时，会显示透明背景。

当内容单行时，一切都很好。

问题是当有更多内容时。叠加的高度不会调整。我已经尝试了top: 0; bottom: 0; height: 100% .action它涵盖了整个表格。

body {
  margin: 0
}
.table {
  display: table;
  width: 100%;
  border-bottom: 1px solid #ccc
}
.tHead,
.tRow {
  display: table-row;
  position: relative;
}
.tCell {
  display: table-cell;
  padding: 5px;
  background: #fff;
  border-top: 1px solid #ccc;
}
.tHead .tCell {
  background: #ccc;
}
.tRow:hover .tCell {
  background: #f4f4f4;

}
.tRow:hover + .tRow .tCell {
  border-color: #000;
}
.tRow .tCell:first-child {
  width: 10px;
  cursor: pointer;
  opacity: 1
}
.menu {
  display: block;

希望这会对你有所帮助。

使用:before作为单元格上的叠加层，并使用~运算符定位单元格。我有同样的要求。这就是我处理它的方式。

答案 1 :(得分：0)

@Tushar ..我注意到表格的底线，div边框永远不会在悬停时更新。fiddle example

.tCell:hover .menu:before, .tCell:hover .menu:after, .tCell:hover .menu { background: #000; }
