Html5 Development
The definition of HTML is Hyper Text Markup Language.
HyperText is the method by which you move around on the web — by clicking on special text called hyperlinks which bring you to the next page. The fact that it is hyper just means it is not linear — i.e. you can go to any place on the Internet whenever you want by clicking on links — there is no set order to do things in. Markup is what HTML tags do to the text inside them. They mark it as a certain type of text ( for example-italicised text). HTML is a language, as it has code-words and syntax like any other language.
WORKING PROCEDURE OF HTML:
HTML consists of a series of short codes typed into a text-file by the site author — these are the tags. The text is then saved as a html file, and viewed through a browser, like Internet Explorer or Netscape Navigator. This browser reads the file and translates the text into a visible form, hopefully rendering the page as the author had intended. Writing your own HTML entails using tags correctly to create your vision. You can use anything from a rudimentary text-editor to a powerful graphical editor to create HTML pages
Benifit of HTML 5 Development
Since the release of the first draft in 2008, most major browsers (yes including IE8) implemented some of the features proposed in this draft and it is already generating a lot of interest from developers. Today we will look at 5 of these exciting HTML 5 features and its implementation.This specification defines the 5th major revision of the core language of the World Wide Web: the Hypertext Markup Language (HTML). In this version, new features are introduced to help Web application authors, new elements are introduced based on research into prevailing authoring practices, and special attention has been given to defining clear conformance criteria for user agents in an effort to improve interoperability.
1) Web Workers: Think of it as Hyper-Threading for web browsers. Separate background threads are used to do processing without effecting the performance of a webpage. This can be very useful for web applications which relies on heavy scripts to perform functions (among other things). Firefox 3.5b has the best implementation of this proposed features. Opera and Safari also supports some elements of this feature.
2) Video Element: You can embed video without having to rely on third-party proprietary plug-ins or codec. You can embed video code with the same amount of ease as you now embed an image with the ability to manipulate videos and built-in video controls among other things.
3) Canvas: Canvas element lets you render graphics and images on the fly. An excellent implementation of this element was done by the developers of Mozilla lab project Bespin. Which is an extensible Web Code Editor using Canvas (among other things). You need to register to try out Bespin. You can see a much simpler implementation of canvas with this drawing board(works with FF 3.5 – Chrome – Opera). All done without having to rely on plug-in, the possibilities are endless.
4) Application caches: The ability to store web apps like email locally and access it without having to connect to the internet or install an external client like Outlook or Thunderbird. Google gears, which helps you access Gmail offline, is an implementation of HTML 5 specifications for Applications Cache (and much more). If you use Google Gears than you are using already using this feature.
5) Geolocation: This API defines location information with high-level interface (GPS) associated with the device hosting the API. Sources of location information includes Global Positioning System (GPS) and network signals such as IP address, RFID, WiFi and Bluetooth MAC addresses, and GSM/CDMA cell IDs.
