Reception

HTML 5 is coming

HTML 5 is going to be the newest installment for the Hyper Text Markup Language, and is long overdue with HTML 4 over 10 years old.

New markup elements with HTML 5

With HTML 5 there will be a list of new markup elements that will replace commonly used <div> elements for key areas of a web page. Here's a list of a few new HTML 5 markup elements:

  • <header>
  • <nav>
  • <article>
  • <section>
  • <aside>
  • <footer>

All common areas that would appear on most web pages, but prior to HTML 5 would have been marked up using <div>s, e.g. <div id="header">, <div id="nav">, etc...

Audio and Video with HTML 5

Prior to HTML 5 audio and video had to be embedded onto a web page either in a flash object or using plugins such as Windows Media Player or QuickTime.

With HTML 5 audio and video will have their own tags and will be embedded onto the web page as an element themselves.

The audio and video markup elements will both have their own attributes such as "src" that will show the audio or video source file, "controls" which will be a boolean to either turn media control on or off for the user, and then also the height and width attributes when using the video element.

When will HTML 5 be standard?

Although HTML 5 has already been in development for a few years, will still need a few years more.

There are teams of people working on HTML 5 and already web browsers are starting to be built HTML 5 ready - so that when HTML 5 is rolled out hopefully most if not all of the newer web browsers will already be able to render the web pages properly.

Security risks with HTML 5

Currently every web browser reads a web page differently, and so people who build malicious viruses or malware and add them to the Internet need to write scripts for these viruses per web browser.

With the introduction of HTML 5 it is hoped that all web browsers will read web pages is near enough the same way.

This does cause a bit of alarm as no longer will virus writers need to write the virus different per web browser - but instead, write it once and it can attack all web browsers.

This risk has been noted in a few website magazines that I've read and so the professionals know about this and are hopefully, therefore, doing something about this.
