my friend has just told me that my website actually looks different on other computers. this is due to fonts. apparently you can change how big you want your fonts to be and because people have done that my website looks rubbish, so i need 2 no if there is any script to disable this.

you could disable it with the use of css, but i do not recommend that, because when u do so then people arent able anymore to change the font size, so you cut a part of the world of from your site.
