title: How to hide scrollbar in iframe using css?
body: <p>I use HTML5.In my <em>iframe</em> , if I use <em>scrolling="no"</em> my browser(chrome) supports it.But some  sites says that <em>scrolling</em> attribute is not supported in HTML5.And I decided to use css but <em>overflow : hidden; overflow-x:hidden; overflow-y:hidden</em> any of it does not effect anything.What should I do? Should I continue to use <em>scrolling="no"</em> becuse it is still usable in HTML5</p>
