我在我的 ASP.NET 应用程序中使用 Bootstrap-Twitter 样式和主内容架构（下面的代码）。第一次加载时一切正常，两个 span6 div 并排，顶部菜单正常。我检查了@media 样式，两个 div 都可以。当任何更新面板执行部分渲染（单击左侧更新面板中的树）时，一切都会发生变化。主要的，我认为关键的问题是现在@media 发生了变化（现在是@media（最大宽度：767px），而在更新之前是@media（最小宽度：1200px））。当您在平板电脑或一些小分辨率中打开时，宽显示器中的显示页面会发生变化，并且仅在更新面板部分呈现时才会发生这种情况。有没有人有这种类型的错误的经验？
