Creating & Managing Highlight Styles
Highlight styles are managed in ACP under Extensions β Group Post Highlight β Highlight Styles. A style isn't tied to any post directly; it's a reusable definition that gets assigned to one or more groups (see Assigning a style to a group). Editing a style updates every group, and every post, using it immediately.
The style list
Each row shows a live swatch preview, the style's name, how many groups currently use it, and actions:
Edit
Open the visual editor for that style.
Duplicate
Create a copy named "Style name (copy)", then jump straight to editing it.
Delete
Remove the style. Blocked while any group still has it assigned; reassign or clear those groups first.
The visual editor
The editor is split into three parts: a live preview, the visual style fields, and custom CSS.
Border, background & text
Border colour / opacity
Blank = no border.
Border width (top/right/bottom/left)
Set independently per edge, 0β50px.
Background colour / opacity
Blank = theme's default post background shows through.
Text colour
Blank = the theme's normal post text colour. Unlike border/background this has no separate opacity slider; it's either the picked colour at full strength, or left alone.
Shadow
Border, background and shadow colours are each built from a hex colour plus a separate 0β100% opacity slider, rather than an alpha channel baked into the hex value.
Shadow colour / opacity
Blank = no shadow.
Offset X / Y
Horizontal / vertical shadow position, -50 to 50px.
Blur / Spread
0β50px blur, -50 to 50px spread.
Inset
Draws the shadow inside the post border instead of outside it.
Badge
A small pill shown under the post title.
Show badge
Master toggle for the badge.
Badge label
Free text, up to 40 characters (e.g. "Admin", "Moderator", "Community Helper"). Left blank, no badge is shown even with the toggle on (this is re-checked at render time, not just when saving).
Badge colour / opacity
Background colour of the pill.
Show icon
Adds an icon before the label.
Icon
Searchable picker of icons; type to filter by name.
The badge only renders in the topic view (viewtopic), not on search results. A highlighted post's border/background still shows correctly everywhere it's opted in, including search results and "Search user's posts", but prosilver's search results template has no template event positioned where the badge needs to render, so it's left off there rather than placed somewhere visually wrong. See Custom & per-theme CSS for the exact wrapper markup this depends on.
The preview panel at the top of the page updates live as you edit any of these fields, so you can see the result before saving.
Custom CSS
Below the visual editor is a Global CSS box for admin-authored CSS layered on top of the generated style. See Custom & per-theme CSS for the selectors to use and how per-theme overrides work.
