This means that some features of HTML5 are ready for implementation while others are still in the design phase and may change.When can I start using HTML5?New features are usually good for developers. Just be aware that authoring tools do not support some features of HTML5 now, and that other features may never get supported. This is important to understand, since content authored by hand now may at some point in the future get processed or edited by an authoring tool in unforeseen ways. For example, using new markup features such as will break HTML Tidy or the many authoring tools that contain HTML Tidy:Star Trek IIThe Wrath of KhanHTML Tidy error:Error: is not recognized!This document contains errors that must be fixed before using HTML Tidy to generate tidied up version.Other HTML5 features such as permitting hyperlinks around block elements, as seen the following markup, may cause unexpected results in authoring tools:NewsCan I author HTML5 with XStandard?New HTML5 elements can be used in XStandard.

What is HTML5 Canvas? Canvas is a new element in HTML5, which provides APIs that allow you to dynamically generate and render graphics, charts, images, and animation. The presence of the Canvas API for HTML5, strengthens the HTML5 platform by providing two-dimensional drawing capabilities. These capabilities are supported on most modern operating systems and browsers.Essentially, Canvas is a bitmap rendering engine, and the drawings are final and cannot be resized. Furthermore, objects drawn on Canvas are not part of the web page's DOM.Within a web page, you can add Canvas elements using the tag. These elements can then be enhanced using JavaScript to build interactivity. For more information, see this link. The new HTML5 Canvas document-type Animate enables you to create an HTML5 Canvas document with rich artwork, graphics, animations, and so on. A new document type (HTML5 Canvas) has been added to Animate that provides native support for creating rich and interactive HTML5 content. It means that you can use the traditional Animate timeline, workspace, and tools to create content, but produce HTML5 output. With a few simple clicks, you are ready to create an HTML5 Canvas doc and generate a fully functional output. To its end, within Animate, the document and publish options are preset to generate HTML5 output. Animate is integrated with CreateJS, which enables rich interactive content on open web technologies via HTML5. Animate generates HTML and JavaScript for content (includes bitmaps, vectors, shapes, sounds, tweens, and so on) created on stage. The output can be run on any device or browser that supports HTML5 Canvas. Animate and the Canvas API Animate publishes to HTML5 by leveraging the Canvas API. Animate seamlessly translates objects created on stage in to their Canvas counterparts. By providing a 1-to-1 mapping of Animate features with the APIs within Canvas, Animate enables you to publish complex content to HTML5. Creating an HTML5 Canvas document To create an HTML5 Canvas document, do the following: Select File > New to display the New Document dialog. Select the Advanced tab from the top of the screen and click the HTML5 Canvas option. This opens
