I made a new CSS file, which simulated 3D cells using different border 
colors for the four sides of each cell. I plan to put this as the new 
default into the distribution. There is also a new ELOG icon. If anyone 
has a better one, please post it here!

The attached test.html (elog:/3) show the different classes in the CSS 
file, thanks to Etienne Van Caille <etienne.vancaillie@mba.be>.
