Shadowbox in Firefox always shows me the scrollbars; With Chrome, IE and Safari works OK. Any one knows how to solve this problem? I tried different things in the shadowbox.css but nothing work.

shadowbox.css

The site where resides the shadowbox iframe is (http://www.miradorhotel.com.co). when you enter the site it automatically pops up.
Thanks. The easiest solution is to change your iframe so that scrolling=”no” to get rid of the scrollbars.
If you’re worried about users on smaller screens, change both the iframe and the table inside it to use fixed sizes instead of percentages, then set scrolling=”no” as previously mentioned.
