Thanks Tomasz; Yes, I'm doing just css and html. I usually do my own versioning
with Save As; this time I did not and I paid the price. I'm using TextWrangler
to write my code.
I am simply not sure what I did other than, while tweaking one thing, I wasn't
mindful of the changes being made to another, so that when I looked at the file
next day, I spotted the problem, but couldn't recall what I'd done immediately
before.
I did find an earlier version in which this code worked fine and was able to
change some other things from memory to get back to where I was.
Maybe I took the chicken way out, and should have put in the time and sweat to
search out what I did wrong...not wanting to spend too much time, tho..
John
