css working on local, but not on remote server

When creating on windows 7 xampp it looks good, but when I upload on Debian VPS, it looks different.

Be careful not to give any info, we love to do blind guesses in the dark - a sure way to solve your problem

Post screenshots. Post your code.

Right click your website, check source code, click css link, check if it's linked to correct place.

Hi Mutikasa

I'd like to help you but without the least bit of information this in fact impossible... What looks different? Screenshots? Code?

cheers olystyle

edit - Actually, ignore most of that

Like others have said: without more details it's hard to make any worth while guesses.

Well, now I removed the button part of CSS code.
CSS is working, no problem with that. It just looks little bit different. For example, button was smaller on server, but h1 tag was little bigger.
Everything is working, just looks different, mostly in the term of sizes of letters and button.
I have very simple website.
Now it seems all OK, maybe that's because of that CSS button, but don't know what could create such behaviour.
Thi is the CSS for that button

You can choose many classes here, but i just put <input type="button" class="button">

p.s.Can someone please tell me how to remove this underline letter after the link?
