Yuck files
Yuck is the custom language to config EWW. Refer the official docs for basic config instructions and syntax.
Note: Splitting Eww Config
There are 2 ways to specify path while including other .yuck files:
Absolute path:
From /
(include "/absolute/path/from/root/to/file.yuck")
Relative path:
Relative to eww config dir
(include "path/relative_to/eww_config_dir/file.yuck")
