[Nfb-web] css tutorial

[Marvin Hunkin]

hi.
well a member of blind geeks.
and asked to write a short basic tutorial on css.
did learn css in my web design course in 2007.
and di use it a bit to tweek a web project recently.
but my question is:
what resources and what links to some tutorials to get a handle on how to 
write a short css tutorial.
and how to write one.
and what do i need to put in it.
just asking.
i do know css, but a bit rusty.
and totally blind.
so the biggest problem, where things are located on screen.
so any one got any ideas where to start and how to write a tutorial for this 
technical group.
Marvin.
