Source: Internet
Author: User

The grunt-contrib-less used in the project, wrote the following less code

. Mapfix{position:fixed;top:10px;width:430px;z-index:100;background: #fff;    -position:absolute;    Top:expression (eval (Document.documentElement.scrollTop));}

Note that the bottom two lines are for compatibility with IE6, that is, fix IE6 fixed. Ie7+ has supported it.

Error after executing the less command

Began to think that is less does not support ie CSS hack, after the discovery is IE css expression problem, Shi long students tell the solution

-top: ~ "Expression (eval (document.documentelement.scrolltop+10));";

Precede with a tilde, followed by double quotation marks. This compiles through.
