我有一个带有固定页眉和页脚的简单网页。页眉为蓝色背景，正文为白色背景，页脚为黑色背景。

当我将浏览器调整为更小的尺寸时，标题的蓝色背景不会改变高度，但内容会溢出到正文中（我使用的是 Dreamweaver 的流体网格布局）。这导致标题的内容看起来像是溢出了标题，因为背景的高度确实变大了，这是我需要的。

CSS：

@charset "utf-8";
/* Simple fluid media
   Note: Fluid media requires that you remove the media's height and width attributes from the HTML
   http://www.alistapart.com/articles/fluid-images/ 
*/
img, object, embed, video {
    max-width: 100%;
}
/* IE 6 does not support max-width so default to width 100% */
.ie6 img {
    width:100%;
}

/*

    dw-num-cols-tablet:     8;
    dw-num-cols-desktop:    10;

你想过使用 jQuery 吗？

$.(windows).resize(function(){
if (windows.hight > XXX ...
      //then ...
});
