It is.
You will need to use CSS.
Here is an easy example of how it can work...
CSS:
div.scroll {overflow : auto;}
HTML:
<div class="scroll"></div>
It's actually better than iframes, because iframes push things to the left making centers look off center before it actually uses the scrollbar, this doesn't do that.
Not to mention I believe it is the valid W3C alternative to iframes.
Good luck!
