HTML 5 also uses (in addition to all the new tags Grammae and Rigaudon wrote) some shorter declarations. For instance,
<!DOCTYPE html public and a bunch of other declarations>
in HTML 5 becomes
<!DOCTYPE html>
And
<style type="text/css"> // Bunch of CSS code</style><script type="text/javascript" src="your source"></script>
Now is only
<style> // Bunch of CSS code</style><script src="your source"></script>
And I think it's pretty safe to use these since even Google uses the new type of declarations...
Hi!@RigaudonThank you for posting the list of new tags being introduced in HTML 5. Apart from the new tags, there are also some enhancements being made to existing tags, such as to the INPUT tag which reduces the need for writing Javascript or server-side code for user input validation. For example, when a user date in a text-box, developers would have to ensure that the date is in the right format and would have to filter the user input to prevent the user from entering unrecognizable characters, such as an ampersand or percentage symbol in the textbox for entering date.The new tags for organization also enable search engines to parse the documents with a greater accuracy. With the current HTML standard, every article is a heading tag followed by a paragraph or a DIV element, though there are some web designers and developers who deviate from the norm and use other elements in place of the heading or the paragraph and DIV elements. A search engine would have to be smart enough to figure out which is which by examining the formatting for article titles or distinguishing between actual article text and other sections of the page.We do have other tags already in place, such as the address tag to indicate that the enclosed text is an address, and the rel attribute to provide metadata about a hyperlink. The problem, however, is that most people do not use these tags and attributes yet. Also, many web browsers do not implement enhancements based on these attributes either - for example, the Opera web browser identifies the home, previous, next etc. attribute values for the rel attribute of hyperlinks.@Gammmae105Efficiency is something that is very subjective. For some people, efficiency is defined as something that runs faster in the browser while others think of efficiency as something that requires very little source code for development. The enhancements to the input tag are some of the coolest enhancements to the HTML standard as many of the web developers and designers put considerable effort to build around the conventional HTML input elements. You might have come across the Peter Blum web controls that have been quite popular in the ASP.NET development world.@web_designerI see the introduction of local storage, enhancements to the form input elements, offline web apps, and web workers as the coolest new features of the HTML 5 standard. I guess this opinion conveys my web development background, and I'm sure most other web developers would look forward to these new features too. While the video and audio HTML elements have been much welcomed, I believe they will not make much of a difference to the average user because Adobe Flash is commonly used for delivering content and is almost uniquitous, except in the Apple world of iPhones, iPod Touches, and iPads.
Well there was Windows ME and of course Windows Vista in which they were not user friendly and created more problems then there should have been. However, other factors came into play as to why Microsoft has dominated the Operating system business and that includes both hard and software support and the biggest one PC customization. User interface and user friendliness are big factor as well, but if Apple were to open up its OS like Microsoft has then it would be different story.
