Twitter引导响应背景图像+；导航+；标题+；wordpress

我正试图在我的WordPress站点中，使用最新版本的bootstrap，在给定页面的背景中显示一个特色图像。我已经创建了几个“长方体”来覆盖不同的渐变/不透明度层以提高可读性，但我不知道如何使所有的东西都工作

这就是它现在的样子：

我想裁剪一个给定高度的图像，而不变形它

HTML代码是：

给我们呈现的HTML代码，而不是PHP。完成，感谢您在@Sidsec9“我想在给定高度裁剪图像，而不使其变形”的通知。在图像周围添加一个包装div。给一定的高度。添加css溢出：隐藏。你想要这样的东西吗？一点也不想要，因为它不能解决响应的大小调整：，@user3333933
