我现在已经使用 w3 验证了 html 和 css，但是当我尝试在不同的屏幕分辨率下测试它时，底部横幅总是向上移动到内容区域。当我在 Internet Explorer 8 中打开所有工具栏时也会发生这种情况。使用我的 1280x1024 显示器在 Firefox 中似乎效果更好。我知道这是一个 CSS 问题，但无法纠正。在这件事上得到一些帮助会很好。

问题是您（过度）使用position: fixed. 固定位置不应用于一般场地布局。它不适用于不同分辨率的浏览器，通常会导致问题。最多应该用于在屏幕的顶部或底部附加一个栏。

您的问题是一个潜在的问题，需要对您的 CSS 进行一些重新设计。
