overflow-x not valid css

[anachronistic]

i'm trying to finish the design on my website, and i got a little bit of this done today, but i went to go validate the css embedded in the document, i get one little error that my overflow-x element that's inside the css embedded in my page is not valid css. ****!

i had:
overflow-x: hidden;
overflow-y: scroll;

a URL for your viewing [removed] (note: don't go to the other pages, they're kinda unreadable right now)

so i did some research on it and found out it was some sort of microsoft implementation, that it's available in firefox 1.5+, and that it's a proposal for css 3.

i'm looking for an easy alternative to hide the horizontal scroll bar. i want the vertical scrollbar to be visible all the time, but i'm not sure if there's an alternative. overflow: auto; would be an option if i had more content on the page (which will soon be) if you guys have any alternatives for XHTML CSS or PHP i am open. I am hesitant about using javascript, but i may have to use it soon.

I don't think we have many webmasters here.. i don't play with CSS much which is very popular these days.. (lazy to learn) still sticking with the usual html.
