Porto WordPress Custom CSS section under Theme Options is based on the Redux Framework. You can certainly write and execute SCSS (Sassy CSS) within a Redux container that uses Ace Editor. However, there are a few things to consider:
Setup: Ensure you have the necessary dependencies installed to compile SCSS if you plan to use it in your project.
Applying Styles: Once your SCSS is compiled into CSS, you can apply the styles to your components, including the Ace Editor container, using standard CSS techniques.
