Just like every year its been a weekend of over indulgence in meats and starches in the name of celebrating Jesus’ day of birth. Enough said about that, its now back to business. I was trying out some of the new features in HTML 5 and was loving it.

For those that don’t already know it, HTML5 is the proposed newest major version of HTML (Hypertext Markup Language). I use the word proposed in the previous line because its important to take note that as the writing of this article, HTML 5 is not a W3C recommendation yet.

Being the next standard that was proposed back in around 2004, HTML 5 is to be the next standard after HTML 4.01, XHTML 1.0 and DOM 2 HTML which aims to reduce the need for propriety plug-in based Rich Internet Application technologies such as Adobe Flash, Sun’s JavaFX and Microsoft’s Silverlight.

HTML5 is being worked on by a group that consists of AOL, Apple, Google, IBM, Microsoft, Mozilla, Nokia, Opera and loads of other vendors.

HTML 5 introduces a number of new tags and drops support for some of them of which I will make mention shortly. In addition to a host of new tags that specify markup, HTML5 specifies scripting application programming interfaces (APIs) and goes ahead to extend the document object model (DOM) interfaces and goes ahead to document them.

Some of these new APIs are:

• Timed Media Playback.
• Document Editing.
• Offline Storage Database.
• Canvass for 2D drawing.
• Drag and Drop (finally ).
• Cross Document Messaging.
• Browser History Management.
• Mime type and protocol handler registration.

In addition to these new APIs there are some new feature that would make it different and build on HTML 4.01 and XHTML 1.0 these include:

• Markup parsing that is not based on SGML.
• Usage of inline SVG and MathML in the text.
• A bunch of new elements as mentioned earlier that I will make mention of.
• New types of form controls such as email, url, search, dates and times.
• Support for PUT and DELETE in addition to POST and GET for HTML forms.
• Depreciated elements have been dropped.
• New attributes such as Ping, char-set and Async on a and area, meta and script.
• Global attributes on all elements.
• Error handling will be flexible on incorrect syntax.

Back to the tags. HTML5 inherits almost all the tags from HTML 4.01, well, almost all. Apparently there are some depreciated tags. Then of course HTML5 adds a few other tags to the existing ones.

The depreciated tags are as follows:

• <acronym> was used to define acronyms in HTML 4.01 examples are UN, WYSIWYG etc. In HTML5 you would have to now use <abbr>.
• <applet> was used to define an embedded applet in previous versions prior to HTML5.
• <basefont> was used to define the default font-color, font-size, or font-family for all the text in a document. Personally I have never used this one.
• <big> was used to make text bigger in relation to other text of the same font-size.
• <center> was used to align text and content to the center.
• <dir> was used for the definition of a directory list.
• <font> was used to define font-face, font-size, and font-color of text. CSS has been favored over this one.
• <frameset> tag was used to define a frame-set, which organized multiple windows also known as frames.
• <frame> tag was used to define one particular frame within a frame-set. <frame> and <frameset> are depreciated in HTML5 because they impact negatively on the usability of a web page.
• <noframes> tag was used to display text for browsers that do not handle frames.
• <s> and <strike> were used to define strike-through text. They have also been depreciated in favor of CSS.
• <tt> was used to define teletype text. CSS is the way to go here.
• <u> was used to define underlined text. As above CSS should be used.
• <xmp> was used to define pre-formatted text. <pre> should be used instead.

That’s it as far as the depreciated tags go. Now onto the new tags included with HTML5.
