In the userContent.css file, User_Defined_Stylesheet, items that are enclosed with /* . . . */ are comments. In order to make some code included there as examples become active, you must remove the /* . . . */ from the code only. EXAMPLE:
/*
* example: use OS colors if none are specified (like IE)
*
* body * { color: inherit; background-color: transparent; }
* html > *, input, textarea { color: WindowText; background-color: Window; }
*/
To make the above active, you would change it as below.
/ * example: use OS colors if none are specified (like IE) */
body * { color: inherit; background-color: transparent; }
html > *, input, textarea { color: WindowText; background-color: Window; }
Regarding the code in the wiki page, it only needs to be copied to the User_Defined_Stylesheet. After the copy, you must save the file. The items that are newly added will take effect after the next restart of KM. If you use the loaded, you may have to restart that also.
