I was given a link for Free PDF
http://reference.sitepoint.com/css
But the Beta expired and their book is out..
The above link is the book.... I've used it some
very good, but I hate reading on Darn Computer screen,
good eyes, but always hated that...
The fellow I am/was doing gratis work... My music
group Purchased the The Ultimate CSS Reference for me.
Its on Amazon.com with free shipping 30 bucks...
I also use this link, really like the search aspects and
results...
http://www.w3schools.com/css/default.asp
Again screen reading, but really excellent material and
examples....The little search box top right opens many
doors...
Wit CSS, think I've really opened
Pandora's box... quite a journey...
I have nothing but admiration for the person/persons
who wrote created the CSS menu/s the first time...
A brilliant use of some very simple code...
Hope this helps you,
Seeker
