I must be the devil, then.  I enjoy playing with them.  And if they're done right they

Clearly he didn't verify the HTML before he released the original version. ;-)

That's the joy of HTML errors - often the output will appear normal until you make some
minor, and apparently irrelevant, change, when it all goes haywire.
