Hi Dreamy Star,
If you are familiar with CSS, that's how Luna Engine works for VXA and MV.
Luna Engine MV is different from its VXA version and slightly harder. We have some videos and tutorials over here: http://www.yanfly.moe/wiki/Luna_Engine_MV_(Visustella)
It doesn't have an editor due to compatibility issues with other plugins. It's probably not gonna be useful for you if you're not familiar with CSS or the concepts around it.
