How do I fix my website so it doesn't appear huge on some computers but small on others?

i really don't know much, so I am probably not even asking correctly.... when I create my website on my home computer it looks great, but when i look at it on my office computer everything is too big. how do i fix this so it automatically adjusts to screen size, or whatever it is.... thanks

i know how to throw in some html, so if there is just a simple code i can use, that would be great!!

I am using firefox at home, and firefox at work... it looks good at home, but not on my firefox at work, nor ie at work.

its not the fonts, its the whole thing.

i don't know xhtml?? using yahoo site builder

It all depends on the browsers you are using?

You can designate a resolution size. I am not sure the code but www.w3schools.org will help ;)

Are you using CSS/XHTML?

Are you using firefox at home and IE at work?

There may be some tips you can do to load certain fonts in CSS depending on the browser opened with.

Look for the page button and change the text size.
