The Blue Bear CSS
I don't know anything about CSS so you will probably find my code a mess. After a few weeks of testing and researching I created an almost complete theme (95% light and dark) that I thought was beautiful. Some things I don't know how to change like the color of the scroll bar, so I use the Frankfurt theme to match the colors.
Some colors are based on Bear.
Most of the fonts I modified myself, the intention was not to hide all the codes, just to make it more discreet to make reading more comfortable.
I will post the fonts used as well.
Enjoy, modify and post your CSS too!
The code is too long, so I couldn't post it directly here.
