页面溢出时展开图像和导航菜单

Question

我有一个网站，其中 2 页内容在小屏幕中溢出，这意味着您必须水平滚动才能查看所有内容。因此，屏幕顶部的菜单和徽标图像在这两页上被截断。菜单和徽标都由母版页加载。我尝试通过使用媒体查询并分配特定宽度来解决此问题，这确实解决了这两个页面的问题，但它导致所有页面在小屏幕上滚动，因为该修复影响了母版页。我认为这是一个非常基本的问题，但令人惊讶的是我找不到任何解决方案。我想知道是否有人对如何解决这个问题有任何想法。

编辑：从我的母版页和样式文件中发布代码。

Answer 1

您可以使用

禁用水平滚动

overflow-x:hidden;

在你的 CSS 中

Answer 2

您似乎在手动滚动自己的响应式媒体查询？我建议使用 Bootstrap v3 - 你可以使用包管理器来设置整个事情。

在您的媒体查询中，您使用像素将固定宽度设置为 1670 像素。在 RWD 中，从不使用固定的宽度单位；它总是以百分比完成。您可以使用 Bootstrap 来避免这些问题，因为所有繁重的工作都已经为您完成了。

对于您的具体问题，您应该针对不同的屏幕分辨率使用不同的媒体屏幕：
