Adjust HTMLPanel Height as paer srcdoc content

I have an HTMPLPanel, It has an Iframeelement inside it. for Iframe I had set srcdoc attribute which is content of an input HTML page. Content is shown fine, but there are display issues the way it is shown.

1. Scroll is hidden for both panel and frame 
2. 2.There is still scroll shown, I feel it comes from HTML 
3. 3.But content shown in very small portion and scroll appears always.even for small HTML content.

Somehow I am not able to increase height of HTML panel so that if content is small it would be visible as a full.

Can anybody provide suggestions
