Web designers will not like it but Web developers will see it as inevitable – the new emerging HTML5 standard is really the recognition that Web 2.0 development trends have taken us to DHTML-Dynamic HTML as the way to design and program Web applications.  But DHTML means designers and developers will require solid knowledge not only of   HTML and CSS but also JavaScript, DOM,  XML and host of Web integration technologies.  Go see the HTML5 Core document at the W3C standards site – and look there for the broad outline. But also here for the core references of information and methods HTML5 adepts will have to know.

HTML5’s  move from design to development is palpable and just reflects the fact that dynamic web sites that can quickly change with tabs, carousels, video and dynamic content capture browser eyeballs. But another factor, self customization, where users at websites can save their favorites, layout and edit their ‘MyWorkspace’ including coloring and styling are also very popular. These type of capabilities imply a website that is “smart” with pre-programmed widgets and event driven routines prepared to be at the beck and call of all a user’s customizing desires.

If you look at the list of references for Core HTML5 one gets a strong idea of whats behind the design of the HTML5 standard:

This list gives a good idea of not only what technologies have been considered but also which ones are likely out of the standard. Thus E4X and Gecko, because they are non-normative, are likely considered but are outside the standard – not good for E4X.

Designers will be looking for HTML5 Design Aids

The consequences of HTML5 going strongly programmatic is that Web designers will be looking for aid and help navigating the new standard to get the most out of it. Actually, designers are already looking and products like Xara Web Designer 6 and EXTjs Designer are filling some of  the need. As well there has been a big  rise in  Photoshop to HTML software and design-to-code agencies. But the simple fact is that major Web Design software like Dreamweaver 5, Eclipse, Netbeans, Aptana Studio and many others have a)failed to deliver a Visual IDE for drag and drop Web Design+Coding and b)are even tardy on delivering smart HTML5 editors with Code Completion and Intellisense. So while Apple and Google tell Web Designers and Developers to go out and use HTML5, the hard reality is that there is an enormous learning curve and the supporting software is largely at the level of NotePad++ and TextEdit.
