**Thanks, Joel, for the excellent post and the explanation.  I didn't know what experiments to perform with that xform so that I could understand its function, and now I do!   I think you should write a few basic tutorials for the rest of us who are either new or catching up.  That might make for more art and fewer 'colourful pictures'! **

**As to my font color... I could use some advice.  I have a very dark background (deep purple) in my CSS stylesheet, and black font color simply disappears.  I am looking for a color that will be seen on all sorts of backgrounds...  any suggestions, anyone?  I went for a middle gray, hoping that it would be visible on more backgrounds than any other color, but if it isn't working, I need input. **

Thanks again!
