Sencha Touch allows you to develop mobile web apps that look and feel native on iPhone, Android, and BlackBerry touch devices.

Built with Web Standards

Sencha Touch is the world's first app framework built specifically to leverage HTML5, CSS3, and Javascript for the highest level of power, flexibility, and optimization. We make specific use of HTML5 to deliver components like audio and video, as well as a localStorage proxy for saving data offline. We have made extensive use of CSS3 in our stylesheets to provide the most robust styling layer possible.

CodeMirror is a JavaScript library that can be used to create a relatively pleasant editor interface for code-like content ― computer programs, HTML markup, and similar. If a mode has been written for the language you are editing, the code will be coloured, and the editor will optionally help you with indentation.

TinyMCE is a platform independent web based Javascript HTML WYSIWYG editor control released as Open Source under LGPL by Moxiecode Systems AB.

How?

Just include Live.js and it will monitor the current page including local CSS and Javascript by sending consecutive HEAD requests to the server. Changes to CSS will be applied dynamically and HTML or Javascript changes will reload the page. Try it!
Where?

Live.js works in Firefox, Chrome, Safari, Opera and IE6+ until proven otherwise. Live.js is independent of the development framework or language you use, whether it be Ruby, Handcraft, Python, Django, NET, Java, Php, Drupal, Joomla or what-have-you.
Why?

The WURFL is an XML configuration file which contains information about capabilities and features of many mobile devices.

The main scope of the file is to collect as much information as we can about all the existing mobile devices that access WAP pages so that developers will be able to build better applications and better services for the users.
