What are "Postboxes"? Facebook has a feature offering colorful backgrounds + for short, text-only posts. Postboxes for Friendica offers something similar, but it is not + limited to short or text-only posts (though it still works best with those). Friendica's gradient and + pattern backgrounds, however, are accomplished with pure CSS (no images), and are + therefore very fast and lightweight.
+ +How to use: Put your text/content inside the "class" BBcode like so:
+ [class=postbox-name]Your Text Here[/class]
+ Type the name in all lowercase letters with no spaces. Each sample below shows the name.
+ Some also show the old names in parenthesis, which are still valid and have been mapped
+ to the new styles. If a style is not available on a given server, or if you misspell the name,
+ the "default" style will be used (inherited font color against theme's post background color).
Limitations: Requires either using the "Frio" theme with the "Bookface" scheme, or + the "Postbox" add-on be installed, or the "Zen Postbox" add-on be installed. Postboxes shared to servers + without them see only the un-styled content fo the Postbox, this includes other platforms like Mastodon, + Bluesky, Tumblr, etc. Note that there are currently issues with how Postboxes display + in posts shared to Diaspora and Hubzilla.
+ +The animated backgrounds shown below are only available if either the "Postbox" or "Zen Postbox" + add-on is installed on the server.
+ +These are only available if either the "Postbox" or "Zen Postbox" + add-on is installed on the Friendica server.
