An example for what Richard mentioned:
This Background is RGB 240,240,240
This Background is RGB 237,237,241
This Background is RGB 224,224,224
This Background is RGB 255,0,0
Pay Attention, COLORREF is 0x00bbggrr (
COLORREF (Windows)[
^]) while in the html-div I used it is 0xrrggbb.
I would have posted this as comment, but comments do not handle the div's. Sorry.
