The look of the forum is set in the Style editor, Tools tab of the administration control panel, Appearance and app section. It customises prosilver, the phpBB style; no other style can be installed.
Colours
- Theme: a ready-made palette, to adjust afterwards.
- Quick palette: choose a main colour and an accent colour; all the others are computed as readable shades, and can still be changed one by one.
- All colours: each colour separately. Clear a value to get the original colour back. An indicator flags hard-to-read colours.
- Font and sizes: the font and text sizes.
Night mode automatically uses a dark version of your colours (see Night mode).
Images and logo
The Images screen replaces the style images, including the logo. Enter an HTTPS address or upload a PNG, JPEG, GIF or WebP file of 5 MiB at most; an uploaded file takes precedence over the address. Tick “Original image” to go back to the prosilver image.
CSS, templates and JavaScript
Editing code is reserved for the founder account. The custom stylesheet applies after the colours and images. Templates are edited without PHP code and without the feature templates. A platform filter checks the saved code and refuses instructions that are not allowed.
Code is prepared as a draft (“Save draft”, invisible on the forum), then “Publish on the board”. “Restore the original” goes back to the prosilver version.
