This causes the blank white screen problem. The page is totally blank until the stylesheet at the bottom is downloaded, on the order of 6-10 seconds for this page. The browser is waiting for the stylesheet to be loaded before it renders anything else in the page, even the static text.
导致的问题就是,页面会有一段时间“朴素”,突然之间又“华丽”,用户体验很不好。
2、尽量使用 <link rel=”stylesheet” href=”http://www.planabc/yuanxin.css” type=”text/css”> 的样式导入方式,而减少 @import 的使用,更勿使用多层嵌套的 @import 。因为在 IE 里, @import 相当于将 <link> 放在页面尾部。
This is a valid syntax, but, even though it's in the document's HEAD, it breaks progressive rendering and instead causes the blank white screen and Flash of Unstyled Content problems.
