###兼容性
Internet Explorer 8 and 9 are also supported, however, please be aware that many CSS3 properties—e.g., rounded corners and shadows—are not supported by IE8. The placeholder attribute is also not supported in either of these versions.
In addition, Internet Explorer 8 requires the use of
respond.js
to enable media query support.
- 只支持到ie8, 且ie8需要js作为补丁支持
media query
- 需将ie强制为
edge
- win8、ie10由于没有区分
device width
和viewport width
,为达到media query
最佳效果,需要css和js补丁
