Acquia Cohesion renames to Site Studio from version 6.2. Tell me more.
No, you cannot use SCSS variables in your codebase inside the Acquia Cohesion interface.
Color tags allow you to create groupings of colors based off of the color tags that you define in the website settings color palette.
To use an SCSS variable, enter your chosen variable into the appropriate CSS property.
Opacity is set using a decimal where 0 is transparent, 0.5 is 50% and 1 is solid.
