HTML contents Editor of an eBook - WYSIWYG/HTML editor + simple data handling

In this project, you will take an existing project a step further by writing backend functions in Javascript and PHP, that allows for HTML content data to be edited. The HTML content data has been prepared and backend has been created. You are expected to do the following with HTML data in a SQL/PHP backend: 1. Given an HTML string from a database column, you are to create or use an existing WYSIWYG HTML editor to allow for it to be edited. It should also have at least these features: a) Group the data together by placing a (div around the selected data) b) Allow for embedding (hopefully using HTML5's simple features) of media assets. ie: additional sound, video and picture (by links to local HD or external data) 2. An editor to directly edit the html contents (not WYSIWYG) - You may use open source programs already out on the market or borrow some code which provides the required functionality. 3. Allow the HTML content of a record to be cut into two records, or two records combined (string combining) Record data sits on a Php/MySQL server (the backend is done, so you can just grab data out of the DB, NOTE: we use MySQLi standard for security reasons)
