Create a Custom Theme

Hi. I am new to RapidWeaver and have been trying to create a custom theme for a while now couldn’t find a way to edit the available themes fully. I tried using the blank theme and importing some HTML and CSS code, but the CSS code doesn’t seem to be accessed for some reason. Any Ideas on How to create a fully custom theme?
Thanks in Advance.

On GitHub there is this link GitHub - realmacsoftware/RWThemeKit: The RapidWeaver Theme SDK

I in the past have used a theme and used to reverse engineer a themes I purchased for specific customers.

Hope that helps but now I use Stacks plugin with Foundry , Foundation or UIKit these will give you a blank slate to do what ever I want.

Thanks mate, that’s quite helpful!!
