John, we're waiting patiently for your results.

The method I would prefer for that purpose is the following:

Choose three characters you don't need otherwise, such as *, $, and §. (If your song is about sex, money, law, or all of these, take different ones.) Use an ordinary editor such as Notepad, write down each chord, followed by the first of those characters, then the corresponding text, then the second or third character depending on whether it's the end of a line.

When you have finished writing the whole song, perform three "search & replace"s to produce the <div> tags as in my example. Note that the latter is an experiment, we may still refine the trick.

And indeed, nobody should post any tags she/he does not understand, even if the visual result seems flawless. Count your end tags etc.
