Wat is een theme

D8 "definition"

A theme is a collection of files that define the presentation layer. You can also create one or more "sub-themes" or variations on a theme.

Inheritance

Sub-themes are just like any other theme, with one difference: They inherit the parent theme's resources. There are no limits on the chaining capabilities connecting sub-themes for their parents. A sub-theme can be a child of another sub-theme, and it can be branched and organized however you see fit. This is what gives sub-themes great potential.
