Now, with the launch of Channel Presence, which allows for real-time information and user detection, we were given the perfect opportunity to create a slick, completely free, open source (MIT-licensed) real-time group live HTML5 chat app.

Check out the HTML5 Chat app, download the code, and see how you can easily create powerful real-time web apps without needing to worry about the complexities around

Customizing The HTML5 Chat Interface

Display styling is located in the default.css CSS3 file.You can modify this file to change the appearance.  Some notable sections include the background image: This section includes the main background image url(chat-bg.jpg) that is used to set the tone of the chat experience. Obviously, you can modify this to fit your needs. The CSS File itself is larger and there is a lot to see. Thankfully all design elements and styles in the User Interface considerations have been properly abstracted into the CSS file.

Main Index File

The  index.html file will contain information regarding the primary content and components pieced together such as the Fonts, CSS and JavaScript.  The default Twitter user is defined in this file as well as all language content.  You can internationalize this file by updating the English words with replacement variables.
