页面布局之多列布局

常见的多列布局：

• 左列定宽，右列自适应

• 右列定宽，左列自适应

• 一列不定宽，一列自适应

• 两侧定宽，中栏自适应

• 多列等分布局

左列定宽，右列自适应

使用float和margin实现

.left {
  float: left;
  width: 100px;
}
.right {
  margin-left: 100px;
}

<div class="float-and-margin">
  <div class="left"></div>
  <div class="right"></div>
</div>

使用float和margin(fix)实现。可以优先渲染右边部分。

.left {
  width: 100px;
  float: left;
}
.right-fix {
  width: 100%;
  margin-left: -100px;
  float: right;
}
.right {
  margin-left: 100px;
}

<div class="float-and-margin-fix">
  <div class="right-fix">
    <div class="right"></div>
  </div>
  <div class="left"></div>
</div>

使用float和overflow实现。

左侧 left 设置float脱离文档流，右侧利用overflow: hidden触发 BFC 模式。 浮动无法影响，隔离其它元素（IE6 不支持）

.left {
  width: 100px;
  float: left;
}
.right {
  overflow: hidden;
}

<div class="float-and-overflow">
  <div class="left"></div>
  <div class="right"></div>
</div>

使用table和table-cell实现

.parent {
  display: table;
  table-layout: fixed;
  width: 100%;
}
.left {
  width: 100px;
  display: table-cell;
}
.right {
  display: table-cell;
}

<div class="table-and-table-cell parent">
  <div class="left"></div>
  <div class="right"></div>
</div>

使用flex布局实现

利用右侧容器的flex:1，均分了剩余的宽度。而align-items默认值为stretch，保证左右高度一致。

.parent {
  display: flex;
}
.left {
  width: 100px;
}
.right {
  flex: 1;
}

<div class="flex-layout parent">
  <div class="left"></div>
  <div class="right"></div>
</div>

使用grid布局实现

.parent {
  display: grid;
  grid-template-columns: 100px 1fr;
}

<div class="grid-layout parent">
  <div class="left"></div>
  <div class="right"></div>
</div>

右列定宽，左列自适应

使用float和margin实现

.left {
  margin-right: -100px;
  width: 100%;
  float: left;
}
.right {
  float: right;
  width: 100px;
}

<div class="float-and-margin">
  <div class="left"></div>
  <div class="right"></div>
</div>

使用table和table-cell实现

  display: table;
  table-layout: fixed;
  width: 100%;

  width: 100px;
