nothing showing in input box in IE if we type anything?

see Name and Email开发者_Go百科 input boxes in header

see here

This seems to be a CSS problem. in IE 6 and 7, the text boxes appear lower in the page than you intended. In IE 8, the text is appearing above the text input boxes.

EDIT:

This is because you have line-height set to 0.5px. Setting it to the same height as the box fixes the problem.

The problem CSS is under the following:

#container #header #signUp INPUT

BTW. In order to test other versions of IE than what you currently have installed, check out IETester
