如果显示网格,代码应类似这样:
<div class="container"> <div class="row"> <div class="col-md-4"><p>Box 1</p></div> <div class="col-md-4"><p>Box 2</p></div> <div class="col-md-4"><p>Box 3</p></div> <div class="col-md-4"><p>Box 4</p></div> <div class="col-md-4"><p>Box 5</p></div> <div class="col-md-4"><p>Box 6</p></div> <div class="col-md-4"><p>Box 7</p></div> <div class="col-md-4"><p>Box 8</p></div> <div class="col-md-4"><p>Box 9</p></div> <div class="col-md-4"><p>Box 10</p></div> <div class="col-md-4"><p>Box 11</p></div> <div class="col-md-4"><p>Box 12</p></div> </div> </div>
其中col-*-*表示不同类型设备下在网格系统中占据的列宽
极小
手机(<768px) |
小
平板(≥768px) |
中
计算机(≥992px) |
大
计算机(≥1200px) |
|
---|---|---|---|---|
container最大宽度 | None (auto) |
750px |
970px |
1170px |
类名前缀 |
.col-xs- |
.col-sm- |
.col-md- |
.col-lg- |
最大列宽 |
Auto |
~62px |
~81px |
~97px |
列间隙 |
15px (i.e. 30px ) |
当列的高度不同时,由于float的作用会破坏网格的结构,可通过使用响应类避免,下面是一个完整的网格代码:
<div class="container"> <div class="row"> <div class="col-sm-6 col-md-4 col-lg-3"><p>Box 1</p></div> <div class="col-sm-6 col-md-4 col-lg-3"><p>Box 2</p></div> <div class="clearfix visible-sm-block"></div> <div class="col-sm-6 col-md-4 col-lg-3"><p>Box 3</p></div> <div class="clearfix visible-md-block"></div> <div class="col-sm-6 col-md-4 col-lg-3"><p>Box 4</p></div> <div class="clearfix visible-sm-block"></div> <div class="clearfix visible-lg-block"></div> <div class="col-sm-6 col-md-4 col-lg-3"><p>Box 5</p></div> <div class="col-sm-6 col-md-4 col-lg-3"><p>Box 6</p></div> <div class="clearfix visible-sm-block"></div> <div class="clearfix visible-md-block"></div> <div class="col-sm-6 col-md-4 col-lg-3"><p>Box 7</p></div> <div class="col-sm-6 col-md-4 col-lg-3"><p>Box 8</p></div> <div class="clearfix visible-sm-block"></div> <div class="clearfix visible-lg-block"></div> <div class="col-sm-6 col-md-4 col-lg-3"><p>Box 9</p></div> <div class="clearfix visible-md-block"></div> <div class="col-sm-6 col-md-4 col-lg-3"><p>Box 10</p></div> <div class="clearfix visible-sm-block"></div> <div class="col-sm-6 col-md-4 col-lg-3"><p>Box 11</p></div> <div class="col-sm-6 col-md-4 col-lg-3"><p>Box 12</p></div> </div> </div>
其中的visible-*-*表示在何种设备下以何种display属性显示,由于极小设备默认为单列显示,因此无需使用响应类定制。
响应类也可用在普通标记中,比如下面的代码:
<p class="visible-xs-block">This paragraph is visible only on extra small devices.</p> <p class="visible-sm-block">This paragraph is visible only on small devices.</p> <p class="visible-md-block">This paragraph is visible only on medium devices.</p> <p class="visible-lg-block">This paragraph is visible only on large devices.</p>
类似的,也可使用hidden-*,设置在特定设备中隐藏:
<p class="hidden-xs">This paragraph is hidden only on extra small devices.</p> <p class="hidden-sm">This paragraph is hidden only on small devices.</p> <p class="hidden-md">This paragraph is hidden only on medium devices.</p> <p class="hidden-lg">This paragraph is hidden only on large devices.</p>
通过响应类还可以设置打印时的格式:
类 | 描述 |
---|---|
|
块元素浏览时隐藏,打印时显示 |
|
内联元素浏览时隐藏,打印时显示 |
|
内联块元素浏览时隐藏,打印时显示 |
|
浏览时显示,打印隐藏 |
