I agree.

I agree again, but things done in CSS also show things that are not seen 
by static images and visa verso. Like how blurred shadows or glows 
overlap and converge creating different effects.

Anyhow, I only have PSP for my graphics program. I will leave the 
graphics for the experts like Brad, etc. with better tools. :-)


Here another test case just with color.

and resizing the window will give this effect.

Notice how when the transparent backgrounds converge (overlap) that a 
new colors appear but with more saturation. This is why I would like to 
have box-shadow shown through transparent backgrounds.


This is why I have said previously that's it good to brainstorm. Brads 
graphics have help me greatly.
