Currently, how are you creating new themes? What’s the best way to start? Just grab all the CSS from core and start changing it?
You can create a normal extension that has LESS code, and just write code that customizes the default design to what you want. You can't at the moment remove core's default CSS styles for the purpose of designing from scratch, but you can add on top of it.
SychO I thought so. But, wanted to ask just in case there was something else I was missing. Thanks so much!
