html - 在 Bootstrap 按钮上放置 H 标签

标签 html css twitter-bootstrap

我正在使用 Bootstrap 3.3.7。我想在小型和大型设备上放置这样的标题。我尝试使用默认的 Bootstrap 类来定位按钮。但我不能让这项工作成为头条新闻。我想尽可能多地使用 Bootstrap 类，所以我不必自定义和覆盖 Bootstrap 类。

如何定位如下图的标题？

There is a demo of the grid here .

            </div>
        </div>
    </div>
    
    
</div>

最佳答案

我会将每个 h3 及其随附的 button 包装在一个 div 中，并使用它同时定位这两个元素。

例如。

<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>
