Hello Friends,
I rear a new term in html "canvas", Please tell me what are the uses of it in programming.

I don't know what kind of a benefit canvas is for me .. or for somebody else... i only know it's just a wrapper for drawing rectangles etc... but it's only a wrapper... you still need a javascript to actually draw the rectangles etc.... Probably it's a benefit for people who wanna create really creative graphic images....

The CANVAS element is embedded right in the HTML. The scripts that draw on it are right in the HTML (or a linked external file) as well. This means that CANVAS element is a part of the document object model or DOM. Flash is an embedded external file. It uses either the EMBED or the OBJECT element to display, and cannot interact directly with the other HTML elements. Because the CANVAS element is part of the DOM, it can interact with the DOM in many ways. For example, you might create an animation that changes when some other part of the page is interacted with—such as a form element being filled in. With Flash the most you could do would be to start the Flash movie or animation, but with CANVAS you could create many different effects, even adding the text from the form field into the animation.
