Correct run-in headings
I’ve recently noticed a couple of blogs that use an awkward “span” kludge to create “run-in” headings. These are both by smart guys who should know better. Instead of using structurally correct headings and paragraphs, the heading text is part of the paragraph, and is just bracketed with SPAN tags so that it can be styled differently.
CSS-2 does include a “run-in” display style that achieves exactly what these guys want, but it is not universally supported. There are a couple of possible workarounds, both of which I’ve documented. One is to float the header; the other is to style the header and the paragraph immediately following as “inline.”
