html – 如何使用CSS网格布局在行表上进行悬停状态

这是一个用CSS Grid Layout创建的表,但是我遇到了问题,我无法在每一行上创建悬停状态.

我只想用CSS.

任何人都可以给我一个解决方案吗？

.table {
  display: grid;
  grid-template-columns: [col-start] auto [col-end];
  grid-template-rows: [header-start] 50px [header-end row-start] auto [row-end];
  grid-auto-rows: auto;
  grid-auto-columns: auto;
  grid-gap: 1px;
}

.table>* {
  background: gray;
  padding: 10px;
}

.heading {
  background: navy;
  color: #fff;
  grid-row: header;
}

<div class="table">
  <div class="heading">Title 1</div>
  <div class="heading">Title 2</div>
  <div class="heading">Title 3</div>
  <div class="heading">Title 4</div>
  <div class="heading">Title 5</div>

  <div class="row">Row 1</div>
  <div class="row">Row 1</div>
  <div class="row">Row 1</div>
  <div class="row">Row 1</div>
  <div class="row">Row 1</div>

  <div class="row">Row 2</div>
  <div class="row">Row 2</div>
  <div class="row">Row 2</div>
  <div class="row">Row 2</div>
  <div class="row">Row 2</div>

  <div class="row">Row 3</div>
  <div class="row">Row 3</div>
  <div class="row">Row 3</div>
  <div class="row">Row 3</div>
  <div class="row">Row 3</div>
</div>

解决方法

这是使用伪元素的技巧.我们的想法是使用元素作为背景,并使其在左侧和右侧溢出,以便它将覆盖所有行.就像那样,如果你将鼠标悬停在行内的任何元素上,你就会改变颜色,就好像你改变了整行的颜色一样.

这个技巧涉及对标记的少量更改以及更多的CSS.

.table {
  display: grid;
  grid-template-columns: [col-start] auto [col-end];
  grid-template-rows: [header-start] 50px [header-end row-start] auto [row-end];
  grid-auto-rows: auto;
  grid-auto-columns: auto;
  grid-gap: 1px;
  overflow: hidden;
  background: gray;
}

.table>* {
  padding: 10px;
  position: relative;
}

.heading {
  background: navy;
  color: #fff;
  grid-row: header;
}

.row span {
  position: relative;
  z-index: 2;
}

.row:before {
  content: "";
  position: absolute;
  top: 0;
  bottom: 0;
  right: -1000%;
  left: -1000%;
  z-index: 1;
}

.row:after {
  content: "";
  position: absolute;
  top: 0;
  bottom: 0;
  right: -1px;
  width: 1px;
  z-index: 2;
  background-color: #fff;
}

.row:nth-child(5n+5)::after {
  bottom: -1px;
  right: 0;
  left: -1000%;
  height: 1px;
  z-index: 3;
  width: auto;
  top: auto;
  background-color: #fff;
}

.row:hover::before {
  background-color: red;
}

<div class="table">
  <div class="heading">Title 1</div>
  <div class="heading">Title 2</div>
  <div class="heading">Title 3</div>
  <div class="heading">Title 4</div>
  <div class="heading">Title 5</div>

  <div class="row"><span>Row 1</span></div>
  <div class="row"><span>Row 1</span></div>
  <div class="row"><span>Row 1</span></div>
  <div class="row"><span>Row 1</span></div>
  <div class="row"><span>Row 1</span></div>

  <div class="row"><span>Row 2</span></div>
  <div class="row"><span>Row 2</span></div>
  <div class="row"><span>Row 2</span></div>
  <div class="row"><span>Row 2</span></div>
  <div class="row"><span>Row 2</span></div>

  <div class="row"><span>Row 3</span></div>
  <div class="row"><span>Row 3</span></div>
  <div class="row"><span>Row 3</span></div>
  <div class="row"><span>Row 3</span></div>
  <div class="row"><span>Row 3</span></div>
</div>
