Hello,
Now i am discussing how to create mobile app with help of HTML5,now every body using tabs, iPhone etc,so web development technology is also updated. to build mobile apps using several HTML5 features—including the new semantic elements, geolocation, audio and video tags, local storage capacity, web forms, and the canvas 2D drawing surface. During the course, you’ll combine HTML5 elements with JavaScript and CSS3 to create apps for Twitter, movie trailers, and an address book.
You can also style your apps to respond to a device’s vertical and horizontal orientation, take advantage of global positioning, draw your own controls and create basic animations.
