in the class side of the library and not at the class side of the class that descrives the thing I want

You might want to read the following article:

  https://medium.com/concerning-pharo/reddit-st-in-10-cool-pharo-classes-1b5327ca0740

sections 7 & 8 are about the Seaside app, but it is simple enough to read completely.

It is a bit old, but as far as I know, it should still work, especially the part that you have trouble with (the CSS/WAComponent interaction). Maybe this helps a bit.

BTW, you can also add a #style method to any component returning a string with CSS.

Oke, so like I did in my last commit here : https://github.com/RoelofWobben/paintings

but still I do not understand why the css is not used.
