如何使用 CSS 网格布局在行 table 上制作悬停状态

Question

这是使用 CSS 网格布局创建的 table，但我有一个问题，我无法在每一行上设置悬停状态。

我只想为此使用 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>

Answer 1

这是一个使用伪元素的技巧。这个想法是将元素用作背景并使其在左侧和右侧溢出，以便它覆盖所有行。就像那样，如果您将鼠标悬停在行内的任何元素上，您会更改颜色，就像您更改了整行的颜色一样。

这个技巧涉及对标记的一些更改，但也有更多 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>

Answer 2

I have solution for your problem. The example below:

.grid .row {
  display: grid;
  grid-template-columns: repeat(4, 1fr);
  border-bottom: 1px solid gray;
}
.grid .row div {
  padding: 10px;
  display: flex;
  align-items: center;
}
.grid .row:last-child {
  border: none;
}
.grid .row:hover {
  background-color: #cccccc;
  transition: .2s all;
}

<div class='grid'>
  <div class='row'>
    <div>Header</div>
    <div>Header</div>
    <div>Header</div>
    <div>Header</div>
  </div>
  <div class='row'>
    <div>Content</div>
    <div>Content</div>
    <div>Content</div>
    <div>Content</div>
  </div>
  <div class='row'>
    <div>Content</div>
    <div>Content</div>
    <div>Content</div>
    <div>Content</div>
  </div>
  <div class='row'>
    <div>Content</div>
    <div>Content</div>
    <div>Content</div>
    <div>Content</div>
  </div>
</div>

Answer 3

这是我的解决方案，基于兄弟组合器。
主要部分是：

.datacell:hover ~ .datarow {
    background-color: rgba(255,255,0,0.5);
}
.datacell:hover ~ .datarow + .datacell ~ .datarow{
    background-color: transparent;
}

片段：

.datatable{
    display:grid;
    grid-gap: 0;
    grid-template-columns: auto 1fr auto;
    position: relative;
}

.datarow{
    grid-column: 1 / 4;
    z-index: 0;
}

.datacell{
    z-index: 1;
    padding: 8px;
    border-bottom: 1px solid #c0c0c0;
}

.datacell:hover ~ .datarow {
    background-color: rgba(255,255,0,0.5);
}
.datacell:hover ~ .datarow + .datacell ~ .datarow{
    background-color: transparent;
}

.row-1{ grid-row: 1;}
.row-2{ grid-row: 2;}
.row-3{ grid-row: 3;}

.col-1{ grid-column: 1;}
.col-2{ grid-column: 2;}
.col-3{ grid-column: 3;}

<div class="datatable">
   <div class="datacell col-1 row-1">Row 1 Column 1</div>
   <div class="datacell col-2 row-1">Row 1 Column 2</div>
   <div class="datacell col-3 row-1">Row 1 Column 3</div>       
   <div class="datarow row-1"></div>

   <div class="datacell col-1 row-2">Row 2 Column 1</div>
   <div class="datacell col-2 row-2">Row 2 Column 2</div>
   <div class="datacell col-3 row-2">Row 2 Column 3</div>       
   <div class="datarow row-2"></div>

   <div class="datacell col-1 row-3">Row 3 Column 1</div>
   <div class="datacell col-2 row-3">Row 3 Column 2</div>
   <div class="datacell col-3 row-3">Row 3 Column 3</div>       
   <div class="datarow row-3"></div>

</div>

html 的结构必须使 .datarow 元素关闭虚拟网格行并跨越所有前面的单元格。为了让单元格和行重叠，需要明确网格内的定位。

Answer 4

由于您将其视为 table，其中元素位于同一行，您还可以将每一行包装在 DIV 中，并将 "display" 设置为 "contents." 这形成了一个用于悬停的无害父元素，然后设置子元素的样式。（显示：Edge 尚不支持内容。）

.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 .row, .table .heading{
  padding: 10px;
  position: relative;
}

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

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

.rowWrapper{
  display: contents;
}

.rowWrapper:hover > div{
  background-color: orange;
}

<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="rowWrapper">
        <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>

    <div class="rowWrapper">
        <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>
      
    <div class="rowWrapper">
        <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>
    
</div>

Answer 5

我遇到了这个问题。首先，我很想知道为什么如果您使用显示网格，为什么不使用网格项 class？没有必要吗？我觉得是这样的。无论如何，答案是，您需要为所有 div 元素提供网格项 class 并将位置设置为 Relative.

.grid-item {
  position: relative;
}

Answer 6

我最终得到了一个不同的解决方案。我的 table 看起来像这样：

.table {
  display: grid;
  grid-template-columns: repeat(3, minmax(0, 1fr));
}

<div class="table">
  <span>head1</span>
  <span>head2</span>
  <span>head3</span>
  <span>row1 col1</span>
  <span>row1 col2</span>
  <span>row1 col3</span>
  <span>row2 col1</span>
  <span>row2 col2</span>
  <span>row2 col3</span>
</div>

现在您需要每行的悬停状态。添加一个元素包装每一行会破坏父网格，因为它实际上是您试图在网格中布局的那些行包装器的子级。另外，我更喜欢：

没有使用 <table>。这大约使所需的行数增加了一倍，并且需要更多样式。
不使用nth-child 百思不得其解
我没有尝试过的一个不错的选择似乎是将每一行包装在 div 中，添加 class .row 和 display: contents，然后用 .row:hover > span 作为选择器，您可以添加 opacity: 0.6。看起来很体面！其他一些答案也朝这个方向发展。

我最终选择了以下我觉得更简单的方法：

.row {
  display: grid;
  grid-template-columns: repeat(3, minmax(0, 1fr));
}

.row:hover {
  opacity: 0.6
}

<div class="row">
  <span>head1</span>
  <span>head2</span>
  <span>head3</span>
</div>
<div class="row">
  <span>row1 col1</span>
  <span>row1 col2</span>
  <span>row1 col3</span>
</div>
<div class="row">
  <span>row2 col1</span>
  <span>row2 col2</span>
  <span>row2 col3</span>
</div>
