1. Canvas
2. SVG
3. Web workers

I think that these three will provide the most benefit to *webapp*, not necessarily webpage, development. As a web app developer, I'm biased, but I do feel that webpages, as a means to provide static information or media (including blogs, wikis, forums, and so on) have just about reached their peak. With the ability to render arbitrary elements and user interfaces and an (admittedly somewhat limited) background processing model, canvas, SVG, and web workers will, in my opinion, spur the development of rich web applications.

I'm really looking forward to the day that I can essentially do away with DOM manipulation, even if its wrapped in a framework.

Most important because they'll have the most effect on my everyday work
* Input types for form fields – No more date pickers, required fields etc
* Media (video and audio) – The death of Flash can't come too soon
* CSS3 decorations - Rounded corners, drop shadows, multiple backgrounds

There are loads of things I'm really looking forward to, but I think these 3 are going to really help the web as a whole.

- File API
- Input types for form fields
- Semantic elements

I would also like to say "a as block-level element", just because it reduces the amount of elements needed in a . Actually can't I just vote for everything? Seriously, HTML5 has long been needed and there isn't much in the spec I will not be using.

* Input types for form fields
* border-radius (and box-shadow)
* File API

As a developer, this three are going to be used daily (and in fact I'm already using the first two to improve the experience in newer browsers).

Practically all of them are quite important, but I will either use them in very few specific cases (if at all) and others, such as SVG and Canvas, will be used by the 3rd party libraries I use in my apps (eg. for charting), but not directly by me.

Sadly I have not had time to look into Canvas, Web Workers, or the File API else I'd possibly be voting on those.

I look forward to your posts on Offline storage. I have been looking at it and can't ever come up with a situation where I'd like to use it that I shouldn't come up with a server side solution to make it work for older clients.

As someone that maintains a CMS, I absolutely hate a element as a block-level element. It makes it damn near impossible to validate the HTML. =/

Am I the only person that cannot wait for datalist to become available in more browsers than just Opera? That element is awesome.

At work, my top 3 is:

2. New form widgets with validation
3. Offline Storage

For my own personal interests:
1. Canvas
2. Web Workers
3. Web Sockets

We don't have a lot of clients that will be utilizing these features. My first list will hopefully save me enough time so that I will get to play with the things on second list.

3. input types for form fields

But many others are really promissing!
Only do I find the semantic part counter productive as I believe that class driven semantic is a better approach but well... I am not a specialist.

1. The a element being valid to contain block level elements
The catch though is that no other interactive elements like buttons or other a elements etc. are allowed inside. I wish there was no catch.

2. The video and audio elements
Though I'd prefer an another method through use of the a element.

3. The section element
Could make compiling documents from different sources easier. Though that's not really an authoring issue. Would have liked to see something CSS-wise like h1:scope {margin-left:1.5em;} and h1:andScope {background:#ddd;padding:0.5em;} or similar.

55 Posted by arlen on 8 May 2010 | Permalink

Looks like a mishmash of HTML5 and CSS3 on that list.

I'll plug for:

Semantic Elements
Input (and other form field) attributes
Offline Storage/Applications

56 Posted by JR on 8 May 2010 | Permalink

1. Semantic Elements
2. Media
3. Canvas

I've recently started working for a company that knows very little about HTML (as far as I can see), especially the semantic use of elements.

They're a long way off from using HTML5 (they still have to support IE6), but I think semantic elements will help a lot once they get around to it. I know I plan to switch to HTML5 on my independent projects, mostly for the semantic markup.

Media and canvas are just cool.

Since you are not talking about semantics, it doesnt make sense to recommend the new semantic elements as a topic for your.

58 Posted by Nick Fitzsimons on 8 May 2010 | Permalink

Semantic elements (in which I include the new values for the type attribute of the input element);

Offline storage;

PUT and DELETE method attribute values for the form element.

59 Posted by Douglas on 9 May 2010 | Permalink

1. SVG, and animation/javascript interactivity with SVG. Compatibility between browsers, and different javascript frameworks to help compatibility (eg. Raphael)
2. Video/Audio
3. Canvas

One thing that is a little annoying is how canvas gets all the attention for being the new way to create awesome vector graphics interfaces, where SVG is probably a much better fit for many cases.

1 is obvious.
2 is just to ease development.
3 is because there is no good way of doing this any other way that is also dynamic and doesn't require JS. there are just too many designs that just must have it.

We have to pick three? Input types for form fields and Widgets, I guess. (Is widgets the thing where we don't have to use iframes anymore? That sounds all right, just talk about the columns thing.)
