浏览器之战进入HTML 5时代

organizers, but the HTML 5 currently still at the experimental stage. At present the most dramatic changes to < > and < > audio video introduction of these two tags. Before, many multimedia in meta function, such as video and animation, interactive, usually need to Flash plugin QuikTime, etc. To realize. But once the HTML 5 is approved, audio and video will be like today's text and images, become the standard parts, and any web page doesn't need any means can be inserted loading player, voice and video put it will greatly reduce the burden of browser, and improve the user experience. The result of this change, the browser can escape is one of many plug-ins and operate independently.
In the image processing, HTML and more powerful image has not only greatly strengthened function: vector diagram and bitmap, built-in to 3D technology, with the support WebGL represented by the technology can help provide hardware 3D accelerated meta with video system, in the browser display smooth 3D scene and model. Maybe in the near future, we can even play in
the web page smoothly to world of warcraft, large 3D games.
Visible, HTML and can become the focus of industry and become the HTML development, precisely because it again strengthen HTML as the foundation of the Web. It freed from the plugin, strengthen the bloated in HTML browsers, is not only the comprehension of the innovation, browsing experience on web browser technology licensing unlikelily again. HTML 5 double-edged sword effect HTML Web world of change to 5 exciting, but it also brings many worries. The most obvious impact is Adobe Flash and Microsoft Silverlight technology.
The five breakthroughs as HTML markup language boundary, has increased a lot has practical value of the API, such
as a Web Database SQL Database objects which API can create long-term reserved under the current session of the data for the browser, and cleared the way work, Again the local documents such as File API through the way to drag on site, even provides an interface to upload data related to provide display upload progress and other information. In these API, no plug-ins, client and completely based on the Web page application has assured.

Internship report (including the following main content: intern purpose and requirements, main contents, practice summarizes etc.) One、Purpose and Requirements: My team do today is widely applied ISAS HTML5 (Hypertext Markup Language). Meta Web standards in almost a decade the great leap forward. And of the previous version, not just to say HTML5 Web content, it's mission is to be a mature Web application platform, in the video, audio, platform, image, animation, and computer interaction are standardized. Although the realization of HTML may still have a long way to go, but HTML 5 are changing Web.
HTML 5 has two characteristics: First, strengthen the Web page performance properties. Besides can depict 2d graphics, video playback and prepared for the audio tags. Second, adding the local database of Web application.
Jon von Tetzchner Opera chief executive, said: "next generation HTML will appear over many technical Adobe Flash, because the open Web standard HTML 5 provides except the rich media network outside Flash content. Indeed, once the HTML standard can support the most 5 graphics and video decoding, we have no reason to continue using third-party proprietary technology.
Second、 The Main Content: The difference between HTML5 and HTML5 is:
1, The new analytical order new elements: section, video, progress, nav, meter, time, aside, canvasinput. 2, The new element: Date and time，email, url. 3, The new general attributes: ping, charset async. 4, The domain properties: id, tabindex, repeat. 5, Remove elements:, font, strike.
HTML 5 will bring? Below are five of the HTML5 the most exciting parts: New, more reasonable Tag, multimedia object will no longer bind embed in the object or all in video, but Tag is the Tag, audio and video are audio Tag. The local database. This function will be embedded within a local SQL database, to speed up the search, interactive and index function cache. At the same time, the program will therefore offline Web itself. Don't need the plugin rich animation. The browser will give parlance object directly on the ability to draw vector graph, this means that we can Silverlight directly from the Flash and displayed in the browser, in graphic or animation. Some of the latest browsers, besides the IE, has begun to support parlance. The browser's real program. The browser will provide the API realize the editor, drag and drop, and various kinds of graphical user interface. Contents modified Tag will be eliminated, and using CSS. Theoretically, HTML and cultivate a new Web standards of soil, let all ideas in his share of the
