I am writing a utility for myself and need content from two sites on the same page. I did it with frames and the main reason I like frames is because it is easy to use the mouse to move the slider and make one page have a greater percentage then the other. See example below. I keep reading that you should not use frames, but I do not know of an alternative that offers the same vertical slider bar that frames does. Any suggestions or opinions would be appreciated.
<frameset cols='50%,50%'>
<frame src='test.php'>
<frame src='test2.php'>
</frameset>
