Of course it helps.
But I am most grateful to Benjamin Hawkes-Lewis for his links. In
particular, * http://css.maxdesign.com.au/selectutorial/ which I just
dashed through and found it most clear and informative. I now understand

coding CSS.
Thank you Nathan, thank you Benjamin & all who were kind and generous
enough to share your invaluable insights. :-*
