Spent a few days creating a website. Needed to upload it today to add a functioning search facility. After uploading, most of the font types, hover behaviour, background colour, font sizes and spacing were completely messed up. I am using HTML and 99% CSS for formatting. All editing done through notepad.

Is there a way I can design a website to behave and look as it does on my local computer?

I am using IE7. Peculiar thing is if I reload the same page, some of the formatting gets fixed, but still most of it is still wrong.
