Or drag ~~~

What's wrong with that IE8? There are so many thieves ~~~ Position: fixed;In IE8, if an element with this attribute exists on the page, the drag and drop may be slow and the link may not be smooth ~~ The same problem also exists in Class D of Yui ~~ Oh, yeah ~~~ Sometimes I think this is a wonderful thing. Sometimes I think it is better to put it in a waste bin to make the page very slow ~~ I'm wondering if this guy is actually internal, that's continuous rendering. It's just built in. If that's the case, it's really better not to forget it. Come and guide me.
