How do I embed my game in a website

Hi.

I have a game in the last version of construct 2, and what I want to do is embed my game in my website.

The problem is that in my website I can't use an iframe and the only way that I can do is put the information of the html of the game in a div inside the site.

I know how to do it, but my question is, how can I embed the game in a div and the game do a fit to the size of this div and not read the size of the full window?

I am exporting the game as a letterbox scale for the responsive.

with iFrames
