Help!! how to view on Mac & PC

[kazzaH]

hi
i'm new to web design and busy learning to create web sites using CSS and XHTML. i am using a mac at work (in my spare time) to create a web page but when i open it at home on a pc it reflows all text and pics!!!

i've been told it has something to do with margins and padding is this right??
Is there a piece of code i can enter in CSS to make sure it views ok on pc and mac? or is it trial an error?

thanks for any help

It's trial and error.
But it depends more on the browser than the operating system.

thank you for replying, ive managed to tweak my margins etc to get it to work on a pc, it overflows on a mac, but for the site i created itl be for home users anyway so theyl have a pc so should be ok (i hope!!!)
