Microsoft IE's bug.

If you visit my blog through Firefox, you can see links underlined as . But if you are using Microsoft IE, you can't see it. Why? Because IE doesn't support this property it claims to.

In MSDN, Microsoft said background property has these values:

{ background: background-color || background-image || background-repeat || background-attachment || background-position}

and it can apply to property A (A HREF=.....). Actually only the background-color is supported.

Update on August 27: After I restarted my computer, I can see the underlines through IE... So everything is fine now... So it's good to complain anything in blog...
