I have a page layout with an inner <div id="content"> element which contains the important stuff on the page. The important part about the design is: #content { height: 300px; width: 500px; overflow: scroll; } Now when the containing text is larger than 300px, I need to be able to scroll it. Is it possible to scroll the <div> , even when the mouse is not hovering the element (arrow keys should also work)?
