This is a really short one. I know we should minimize or eliminate the use of iframes. However, from time to time we use iframes. IE and FF allow the use of overflow: hidden to hide iframes, but, this does not work in Safari or Chrome. Be aware, the following does work:
/* take care of IE and FF */
iframe { overflow: hidden ; }
/* take care of Chrome & Safari */
iframe::-webkit-scrollbar { display: none ; }
Hope that helps you in the future.
