Iframe 100% height not working

Question

I created side panels for the client and the height of 100% in absolute position is not showing anything in the iframe. Below is the attached image of the iframe (id starts with ebDiv), the height has changed to 100% and it shows nothing. I am setting height to 920px to make it work but it should be 100% and if i change the position from fixed to absolute and height 100% then it works but 100% height is not showing in absolute position.
