custom post style

 Custom post style  is the practice of styling individual posts differently from the rest of the site styles.

Why
There are at least a few reasons why you may want to support custom post styles.
 * special styling for a holiday
 * testing / showing / teaching new styles
 * post with a complicated table that needs custom styling

How to
No general recommended technique yet. Check examples and brainstorming and try similar approaches.

Tantek
undefined using Falcon has custom post styles since 2015-07-04, e.g. added as an update to one recent post in particular: Method: Itch previously documented:
 * http://tantek.com/2015/178/t1/lovewins-css3-pride-rainbow-background
 * use  directly inside an h-entry in storage
 * retrieve that like any h-entry property and display as the last style element before the close  on the permalink for that post, again directly inside the h-entry, so it applies to it.
 * use  to show custom post style on post in-stream (e.g. on homepage)
 * Note: As of 2015-07-03 only Firefox desktop/Android/OS supports style scoped - but maybe that's ok and will provide a good real world use-case for other browsers to add support.

Tumblr allows post styles in the same way as Blogger.
