html - 使用 float 项的 CSS 网格

Question

我正在尝试实现一个简单的网格，每行有 3 个正方形项，每个项最多可以有 3 行/列。这是我到目前为止所拥有的:

HTML:

<div class="layout-grid">
 <a href="#" class="block" data-rows="2" data-cols="2"></a>
 <a href="#" class="block" data-rows="1" data-cols="1"></a>
 <a href="#" class="block" data-rows="1" data-cols="1"></a>
 <a href="#" class="block" data-rows="1" data-cols="1"></a>
 <a href="#" class="block" data-rows="1" data-cols="1"></a>
 <a href="#" class="block" data-rows="1" data-cols="1"></a>
 <a href="#" class="block" data-rows="1" data-cols="3"></a>
</div>

CSS:

.layout-grid { overflow: hidden; max-width: 800px; width: 100%; }
.layout-grid .block { position: relative; display: block; float: left; background-color: green; height: auto; transition: all .3s ease; }
.layout-grid .block:hover { opacity: .2; }
.layout-grid .block:nth-child(odd) { background-color: blue; }
.layout-grid .block[data-cols="1"] { width: 33.33333333333%; }
.layout-grid .block[data-cols="2"] { width: 66.66666666666%; }
.layout-grid .block[data-cols="3"] { width: 100%; }
.layout-grid .block[data-rows="1"] { padding-top: 33.33333333333%; }
.layout-grid .block[data-rows="2"] { padding-top: 66.66666666666%; }
.layout-grid .block[data-rows="3"] { padding-top: 100%; }

这很好用。但是，如果我尝试添加一个超过 1 行的元素，它不会:

新的 HTML:

<div class="layout-grid">
 <a href="#" class="block" data-rows="2" data-cols="2"></a>
 <a href="#" class="block" data-rows="1" data-cols="1"></a>
 <a href="#" class="block" data-rows="1" data-cols="1"></a>
 <a href="#" class="block" data-rows="1" data-cols="1"></a>
 <a href="#" class="block" data-rows="1" data-cols="1"></a>
 <a href="#" class="block" data-rows="2" data-cols="1"></a>
 <a href="#" class="block" data-rows="1" data-cols="1"></a>
 <a href="#" class="block" data-rows="1" data-cols="1"></a>
</div>

有什么我可以做的吗？

您可以使用 CSS Grid layout此处 - 并非仅在现代浏览器中受支持(参见 support info )。在这里，您可以使用 3 列布局并跨越行和/或列以获得所需的布局 - 请参阅下面的两种布局演示:

.layout-grid {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr; /* 3 columns */
  width: 100%;
  max-width: 800px;
}

.layout-grid .block {
  background-color: green;
  transition: all .3s ease;
  padding-top: 100%; /* set height of block */
}

.layout-grid .block:hover {
  opacity: .2;
}

.layout-grid .block:nth-child(odd) {
  background-color: blue;
}

.layout-grid .block[data-cols="2"] {
  grid-column: span 2; /* occupy 2 columns */
  grid-row: span 2; /* occupy 2 rows */
}

.layout-grid .block[data-cols="3"] {
  grid-column: span 3; /* occupy 3 columns */
  grid-row: span 3; /* occupy 3 rows */
}

.layout-grid .block[data-rows="2"] {
  grid-row: span 2; /* occupy 2 rows */
}

.layout-grid .block[data-rows="3"] {
  grid-row: span 3; /* occupy 3 rows */
}

<div class="layout-grid">
  <a href="#" class="block" data-rows="2" data-cols="2"></a>
  <a href="#" class="block" data-rows="1" data-cols="1"></a>
  <a href="#" class="block" data-rows="1" data-cols="1"></a>
  <a href="#" class="block" data-rows="1" data-cols="1"></a>
  <a href="#" class="block" data-rows="1" data-cols="1"></a>
  <a href="#" class="block" data-rows="1" data-cols="1"></a>
  <a href="#" class="block" data-rows="1" data-cols="3"></a>
</div>
