A tag that I haven't checked recently to see if it's still viable is the <pre> tag.

This should display always in a monospaced font without "collapsing the spaces" as html usually does.

If you type out a lyric in a monospaced font like Courier, with the chords above where they happen, and adjust the spaces so that everything lines up, you should be able to reliably post lyrics with chords in "book style" fairly easily by pasting your composition between <pre> and </pre> tags.

  A    G     A
  Mary had a Little Lamb
  

(Don't try to play it. I made up the chords at random.)
