How to add an iframe in wordpress theme above the header?

I would like to add an iframe above the header of the wp theme. Just like those in the “themeforest.net” and “btemplates.com”. Please give me a detail tutorial coz I’m not much familiar with php and wordpress. :slight_smile:

First of all, is the iframe content / src going to be static or dynamic depending on the page? If static then you can literally just place some iFrame constructor code in your page.php and your single.php in your WP theme.

I want an iframe similar to themeforest.net where they view those demo links opened with an iframe. Can you me a code or something as to how I should do it on my theme?
