HTML5, Video, Canvas, and Ext JS
January 14, 2010

HTML5 is coming. All of us at Ext are excited to embrace the new standard as it gains acceptance. This post will examine two notable HTML5 developments - Video and Canvas. The video tag allows for native video rendering, removing the current need for third-party plugins like Flash. Likewise, the canvas tag has a clean yet very powerful API allowing you to draw complex graphics at the pixel level.

“Ext provided a flexible training schedule and focused on our specific areas of interest. Coupled with their top-notch instructors, we were able to become effective immediately.”
