Upon validating for HTML5 using W3's Validator service, I'm getting the following error message:
"The scrolling attribute on the iframe element is obsolete. Use CSS instead."
In case I'm doing something wrong, here is the page in question: http://www.brnaterweb.com/staging/catalystrecording/clients.
If you visit the link, please remember I am still fixing optimizing cross-compatibility, so on some browsers it may look jumbled due to the CSS framework being used.
