Adding something to every page

[Omir]

Sorry it's probably been asked before but I couldn't find from a search.

I'm looking for the easiest way to add a custom div to every page from PHP side rather than inserting to the dom with JS?

it depends where on the screen you want it. both the classic and larry skins have have an includes folder with header/footer files. you can also do it with a plugin using the render_page hook.

I want to add it as first child of the body tag ideally
