Adapt Learning Community: CSS editing tool?

Hi, I´m wondering if there is any good CSS editing tool

with wysiwyg interface that works with editing the framework?

What do you use when you create new themes?

I tired of searching in inspector for classes and likes!

I use the Atom editor: https://atom.io .

I second Atom. It doesn't have all of the features of Sublime Text 3 but, I prefer the syntax highlighting and the integration with Github desktop.

Thanks I try that out!
