demarcate.js is a new open source project to create an in-line or in-place markdown editor. This allows you to edit an HTML page by clicking on elements and typing in a box that appears in their place.
The contents of the page can then be retrieved in Markdown encoded text which can be saved to a database to persist changes.
demarcate.js was designed to become the main editor for textr, an online
publishing service. You can see the source and browse some more demos at the
github page: [https://github.com/will-hart/demarcate.js].
