将H标记放在引导按钮上

twitter-bootstrap css html

MK-DK · 技术社区 · 7 年前

我正在使用引导程序3.3.7。我想把我的头条新闻放在小型和大型设备上。我尝试使用默认的引导程序类来定位按钮。但我不能在头条上报道这件事。我希望尽可能多地使用引导类,所以我不必自定义和覆盖引导类。

如何定位标题,如下图所示?

我会把每个包起来 h3 及其伴随物 button 在一个 div 并使用它同时定位两个元素。

如。

<h3 class="centered">HEADLINE</h3>
<button class="btn btn-default centered">See Offer</button>

会变成

<div class="centered">
    <h3>HEADLINE</h3>
    <button class="btn btn-default">See Offer</button>
</div>
