"Gradient" option type

[ValerioLyndon]

Has this feature been requested already?

• I have searched the existing issues and this is a new request.

What is your desired feature/change?

Add an option type for gradients. This gradient type could present a novice-friendly interface ala cssgradient.io. This option should provide the full breadth of gradient options i.e linear, radial, repeating (if possible).

Why should this be added?

Gradient formatting can be confusing even for me, despite working with CSS so often. Having a friendly interface would be a clear improvement.

Additional notes

Could either be a qualifier of "color" type or its own type. Probably be better as it's own type for code clarity and because it is used in different areas of the css.

Supporting "repeating" gradients may be quite difficult. Since their use is uncommon, I don't think they are a necessity for a first public version.
