wysihtml5 0.3.0

wysihtml5 is an open source rich text editor based on HTML5 technology and the progressive-enhancement approach.
It uses a sophisticated security concept and aims to generate fully valid HTML5 markup by preventing unmaintainable tag soups and inline styles.
The code is completely library agnostic: No jQuery, Prototype or similar is required.

This project was initiated and is supported by the XING AG. Thanks!

Features

• Auto linking of urls as-you-type
• Generates valid and semantic HTML5 markup (no <font>)
• Uses class-names instead of inline styles
• Unifies line-break handling across browsers (hitting enter will create <br> instead of <p> or <div>)
• Auto-parses content inserted via copy & paste (from Word, Powerpoint, PDF, other web pages, …)
• Converts invalid or unknown html tags into valid/similar tags
• Source code view for users with HTML skills
• Uses sandboxed iframes in order to prevent identity theft through XSS
• Editor inherits styles and attributes (placeholder, autofocus, …) from original textarea (you only have to style one element)
• Speech-input for Chrome

Browser Support

The rich text editing interface is supported in IE8+, FF 3.5+, Safari 4+, Safari on iOS 5+, Opera 11+ and Chrome.
Graceful Degradation: Users with other browsers will see the textarea and are still able to write plain HTML by themselves.

Research

Before starting wysihtml5 we spent a lot of time investigating the different browsers and their behaviors.
