我正在使用 Twitter 的 Bootsrap 完成我的第一个项目。我的前端和 CSS 技能刚刚起步，我正在努力更好地理解 CSS 和响应式布局。我试图理解为什么在较小的显示器上查看时我的 H2 类没有分开，但在完整的桌面视图上查看时它们很好。
我总体上喜欢 Bootstrap，但我仍然卡住了。我已经尝试了多种补救措施并进行了高低搜索，但我仍然无法确定实现这些图像 div 标题的确切原因或更好的方法。
我的项目是在主页 (index.html) 上创建一个包含 6 个图像块的画廊站点。稍后我将添加一些 JavaScript、模式和工具提示等。现在我需要让我的布局清晰并正常工作。
我决定使用流体布局。我创建了一个“流体容器”，然后用一些行和跨度填充它。我的代码如下所示：

现在我已经布置了一个响应式主题。我创建了一个流体容器。在流体容器内部，我创建了一行流体，其中有 3 个跨度 4。在一个容器内有两行这些 span4。
我正在寻求帮助，以了解我在这里的 H2 类的 CSS 做错了什么。
我所做的是为每个图像图块（div）创建一些 h2 替代品。H2 定义了我希望每个标题的标题的方式。由于磁贴的标题将位于不同的背景图像上，我认为我需要能够根据每个图像唯一地定位标题。我希望使用一些背景不透明度来帮助标题从背景图像中弹出更多。
我的理解是自定义 h2 选择器将允许我为我在其中选择自定义 h2 样式的任何 div 创建独特的样式。为什么在小屏幕上观看时 h2 样式都保持链接，这让我很困惑。
当我在小显示器中查看时，为什么我的 H2 都聚集在一个图像平铺 div 上？我错过了什么或搞砸了什么。我感谢任何和所有帮助，并将 +1 最佳答案。
谢谢
