ElvUI skinning guide/documentation
 

Is there a guide/documentation for skinning with ElvUI? Specifically, the API to do the skinning on controls. I'm having problems skinning a custom scrollbar. A casual look at the code suggests I may need to do everything by hand since no component of this scrollbar is named nor using the same parentKeys.

You can also look at AddOnSkins for inspiration.

There is no public API that I know, but ElvUI\Modules\skins.lua has the code to skin most things.

You are much likelier to get ElvUI coding help on their own website forums.
