How do you test for something in a certain area of the page with RSpec / Capybara? (view test)

I’m used to doing

it “displays the controls link” do
render
rendered.should have_selector(“a#controls”)
end

…or using rendered.should have_content, but how would you test for
something specifically in an area of the page? e.g.
rendered.should have_content(“Admin”) in the “div#logo_area” or
something?

I kind of wish there were many clear examples online…
