资 源 简 介
There has been considerable enthusiasm about the new capabilities of HTML5, and even suggestions that
no other technologies or products are necessary to produce dynamic, engrossing, interactive web sites.
That may be overstating things, but it is true the new features are exciting. It now is possible, using just
HTML5, Cascading Style Sheets, and JavaScript, to draw lines, arcs, circles and ovals on the screen and
specify events and event handling to produce animation and respond to user actions. You can include
video and audio on your web site with standard controls, or place the video or audio in your application
exactly when needed. You can create forms that validate the input and provide immediate feedback to
users. You can use a facility similar to cookies to store information on the client computer. And you can
use new elements, such as header and footer, to help structure your documents.
