## Description
|
||
<section id="description">通常，具有<code>btn</code>和<code>btn-default</code>类的<code>button</code>元素仅与它们包含的文本一样宽。例如： <code><button class="btn btn-default">Submit</button></code>此按钮只能与“提交”一词一样宽。 <button class="btn btn-default">提交</button>通过使用附加的<code>btn-block</code>类来阻止元素，您的按钮将拉伸以填充页面的整个水平空间，其后面的任何元素将流到块下方的“新行”。 <code><button class="btn btn-default btn-block">Submit</button></code>此按钮占用可用宽度的100％。 <button class="btn btn-default btn-block">提交</button>请注意，这些按钮仍需要<code>btn</code>类。将Bootstrap的<code>btn-block</code>类添加到Bootstrap按钮。 </section>
