Adding custom divs?

[vigormortis]

I'm trying to add custom divs to my T3 Blank template: first is to create a shadow around the whole page and the second to create a floating menu on the side. I tried by adding markup="2" option in the layout but that's not it.

Can someone point me to the right php file/method how to create those divs?

Someone in the forum mentioned that it's possible to start the div in the starting block using layout and then end it in the ending block, but I just get the message that something's wrong with the code and I can't save it.

Hi vigormortis

Could you clarify more about your issue ? It is better if you have some screenshot that indicate what you want.

Thanks,
