Group Post Highlight

Let members of chosen groups highlight their own posts with their group's colour.

Group Post Highlight lets you define reusable highlight styles (border, background, text colour, drop shadow and an optional badge) and assign one to a group. Members of that group can then opt in to highlighting their own posts with it, using a toggle on the reply and edit forms.

Requires phpBB 3.3.x and PHP 7.1+.

How it works

1. Create a highlight style in ACP under Extensions → Group Post Highlight → Highlight Styles: pick colours, border, shadow and an optional badge, previewed live as you build it.

2. Assign the style to a group in ACP under Users & Groups → Groups, and choose whether it's on by default for new posts.

3. Members opt in per post using the checkbox on the reply/edit form and quick reply. Only members whose default group has a style assigned see the toggle at all.

A post's appearance is never "baked in"; it's resolved live from the poster's current default group every time the post is rendered, the same way phpBB already resolves username colour. Only the opt-in choice itself is stored per post, so editing a style in ACP instantly updates every past post using it.
