Problem/Motivation

Drupal's current theme system that has still lots of concepts from ancient Drupal versions has shown us it might need some upgrades. Examples like #2566775: [Voltron patch] Move all remaining *.admin.theme.css to Seven → and #2575421: Add a Stable base theme to core and make it the default if a base theme is not specified → shows us that the technical limitations of the current theme system, and forces us to make unpleasant decisions.

Biggest problems are:

  • There is separation between admin and user interfaces even though they mix up
  • Too many things work still by magic (hooks) and requires knowledge of how the system is supposed to be used
  • Supporting BC for frontend is expensive

    Thank you for creating this issue to improve Drupal.

    We are working to decide if this task is still relevant to a currently supported version of Drupal. There hasn't been any discussion here for over 8 years which suggests that this has either been implemented or is no longer relevant. Your thoughts on this will allow a decision to be made.

    Since we need more information to move forward with this issue, the status is now Postponed (maintainer needs more info). If we don't receive additional information to help with the issue, it may be closed after three months.

    Thanks!
