what K. Ivanov said.
and please consider using browser tools to debug these things.
There is:
- developer tools in IE
- Firebug addon for firefox
- and developer tools in chrome.
and to research hometask "css reset"
Different browsers have different default styles for elements for documents without styles that look semi-sequential. These styles also include registration and fields. That is why you have an add-on in which you do not reset .
