<h1>Layout 布局</h1>
<h4>通过基础的 24 分栏，迅速简便地创建布局。</h4>
<h2>一、基础布局</h2>
<h5>使用单一分栏创建基础的栅格布局。</h5>
<h5>通过 row 和 col 组件，并通过 col 组件的 span 属性我们就可以自由地组合布局。</h5>
<p>
el-row的gutter属性： 栅格间隔； 默认值0；
<br/>
el-col的span属性： 栅格占据的列数，默认值24；
</p>
<!--
<el-row :gutter="10">
<el-col span="32" :span="8"> <div></div></el-col> 8/32 即此div显示宽度为1/4
</el-row>
-->
<el-row>
<el-col :span="24"><div class="grid-content bg-purple-dark"></div></el-col>
</el-row>
<el-row>
<el-col :span="12"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="12"><div class="grid-content bg-purple-light"></div></el-col>
</el-row>
<el-row>
<el-col :span="8"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="8"><div class="grid-content bg-purple-light"></div></el-col>
<el-col :span="8"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row>
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="6"><div class="grid-content bg-purple-light"></div></el-col>
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="6"><div class="grid-content bg-purple-light"></div></el-col>
</el-row>
<el-row>
<el-col :span="4"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="4"><div class="grid-content bg-purple-light"></div></el-col>
<el-col :span="4"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="4"><div class="grid-content bg-purple-light"></div></el-col>
<el-col :span="4"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="4"><div class="grid-content bg-purple-light"></div></el-col>
</el-row>
<h2>二、分栏间隔</h2>
<h5>分栏之间存在间隔。Row 组件 提供 gutter 属性来指定每一栏之间的间隔，默认间隔为 0。</h5>
<el-row :gutter="20">
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<h2>三、混合布局</h2>
<h5>通过基础的 1/24 分栏任意扩展组合形成较为复杂的混合布局。</h5>
<el-row :gutter="20">
<el-col :span="16"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="8"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row :gutter="20">
<el-col :span="8"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="8"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="4"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="4"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row :gutter="20">
<el-col :span="4"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="16"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="4"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<h2>四、分栏偏移</h2>
<h5>支持偏移指定的栏数。通过制定 col 组件的 offset 属性可以指定分栏偏移的栏数。</h5>
<el-row :gutter="20">
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="6" :offset="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row :gutter="20">
<el-col :span="6" :offset="6"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="6" :offset="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row :gutter="20">
<el-col :span="12" :offset="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<h2>五、对齐方式</h2>
<h5>通过 flex 布局来对分栏进行灵活的对齐。</h5>
<p>将 type 属性赋值为 'flex'，可以启用 flex 布局，并可通过 justify 属性来指定 start, center, end, space-between, space-around 其中的值来定义子元素的排版方式。</p>
<el-row type="flex" class="row-bg">
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="6"><div class="grid-content bg-purple-light"></div></el-col>
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row type="flex" class="row-bg" justify="center">
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="6"><div class="grid-content bg-purple-light"></div></el-col>
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row type="flex" class="row-bg" justify="end">
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="6"><div class="grid-content bg-purple-light"></div></el-col>
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row type="flex" class="row-bg" justify="space-between">
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="6"><div class="grid-content bg-purple-light"></div></el-col>
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row type="flex" class="row-bg" justify="space-around">
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
<el-col :span="6"><div class="grid-content bg-purple-light"></div></el-col>
<el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<h2>六、响应式布局</h2>
<h5>参照了 Bootstrap 的 响应式设计，预设了五个响应尺寸：xs、sm、md、lg 和 xl。</h5>
<el-row :gutter="10">
<el-col :xs="8" :sm="6" :md="4" :lg="3" :xl="1"><div class="grid-content bg-purple"></div></el-col>
<el-col :xs="4" :sm="6" :md="8" :lg="9" :xl="11"><div class="grid-content bg-purple-light"></div></el-col>
<el-col :xs="4" :sm="6" :md="8" :lg="9" :xl="11"><div class="grid-content bg-purple"></div></el-col>
<el-col :xs="8" :sm="6" :md="4" :lg="3" :xl="1"><div class="grid-content bg-purple-light"></div></el-col>
</el-row>
<h2>基于断点的隐藏类</h2>
<p>
Element 额外提供了一系列类名，用于在某些条件下隐藏元素。这些类名可以添加在任何 DOM 元素或自定义组件上。如果需要，请自行引入以下文件
import 'element-ui/lib/theme-chalk/display.css';
</p>
<h4>包含的类名及其含义为：</h4>
<ul id="ulist">
<li>hidden-xs-only - 当视口在 xs 尺寸时隐藏</li>
<li>hidden-sm-only - 当视口在 sm 尺寸时隐藏</li>
<li>hidden-sm-and-down - 当视口在 sm 及以下尺寸时隐藏</li>
<li>hidden-sm-and-up - 当视口在 sm 及以上尺寸时隐藏</li>
<li>hidden-md-only - 当视口在 md 尺寸时隐藏</li>
<li>hidden-md-and-down - 当视口在 md 及以下尺寸时隐藏</li>
<li>hidden-md-and-up - 当视口在 md 及以上尺寸时隐藏</li>
<li>hidden-lg-only - 当视口在 lg 尺寸时隐藏</li>
<li>hidden-lg-and-down - 当视口在 lg 及以下尺寸时隐藏</li>
<li>hidden-lg-and-up - 当视口在 lg 及以上尺寸时隐藏</li>
<li>hidden-xl-only - 当视口在 xl 尺寸时隐藏</li>
</ul>
