[NSFW] How to Insert a MastHead on Top of Page

I wish to insert a masthead ad on top of the page (such as the index page) but before every content on page, so that the ad shows on top of the page before everything else.

I tried to add the code before content on index page but it doesnt put it on the extreme top of the page.

Can someone please tell me the way to use Ad Inserter to put a ad code on extreme top of the page for desktop and mobile.

Regards
