Code for color background behind text

[polara]

What is the CSS code to control the size of a color background behind header text so that it spans ONLY as high and wide as the text itself, NOT the entire width of the page?

Where in ur site, under wich title or wich h1,2,3 ......

I meant this as a general question, but how about behind the camera info in any gallery? Or behind the h2 title? Most people just seem to use a bg that spans across the entire screen even if their title is only 1 or 2 words.
