Odd code during post view

Odd looking code during post view, Logosizes, Ads & locations

Sadly there is no where to post images and screenshots so I will try and explain in text:

• There is some odd code, showing on the posts, its right at the top left of the screen and looks like there is some malformed code.
• I have no idea how to add adverts i would like to do the same as your  your demo site at the header, un the homepage body and the posts / categories
• I would like to use a different logosize on tablet / mobile view it is very small indeed
• the numbers and text in the daily article counter in the nav bar crush up on tablet / responsive action.

Is there a basic user manual? I could probably solve most of the above questions.

Kind Regards,
