HTML5 paves the way for a browser-based universe, and javascript is its shining star. Go beyond rounded corners and <section> tags and bask in the glory of dynamic stylesheets, CSS3 and responsive UI! Wield the awesome power of web storage, web sockets and device access! Conquer your single page app with event-oriented programming and client-side MVC! Even if you're not launching spaceships from the Chrome Web Store, you'll work faster and code better with emerging technologies and tool sets designed to manage complex, browser-based apps, viewed on any device. Websites are for wusses. Web apps = world domination.
This session explains the basic concepts in browser implementations of core Web document technologies (HTML, XHTML, CSS, and SVG), explains their general performance characteristics and how they interact with Javascript, and explains common optimizations (such as coalescing changes) that browsers make. Rather than presenting specific techniques authors can use, the goal is to build understanding of the performance characteristics of the Web platform so authors can have ideas of what things are likely to be fast or slow, and what types of changes they can experiment with to improve the performance of their Web pages.

In this panel, you will get to ask questions and be informed about the state of CSS, where we are at, what is pending, what we can look forward to, to some of the working group members who are hard at work to implement the various specs.
We will also be discussing the support for CSS4 specifications, what we can expect in the future and how it will be useful for web developers and designers. Here is your chance to ask the experts and implementors at the cutting edge of CSS on what to expect and how to use the new technologies now.

In this one hour tutorial workshop, you will become skilled in CSS3 selectors, transforms, transitions and animations. We will work through an animation examples, creating different paths, timing and effects, exploring linear gradients opacity, alpha transparency, border-radius, text-shadows, transforms, transitions and mostly animations. The code example will be provided participants can play with the code, going from novice to skilled without heavy note taking.
Simplify and speed up your CSS development with Sass. Overcome browser differences – particularly with CSS3 – and build grids the right way with Compass. Sass is a CSS meta language that brings more functional programming to the css language and complies to standard browser supported CSS. It adds tools like variables, functions, and mixins, as well as compilation tools for debugging and optimization. Compass builds an additional framework of tools on top of Sass. It adds mixins for almost all the new CSS3 modules to abstract away syntax inconsistencies and browser prefixes. It also enables the development of CSS frameworks *the right way*, using semantic classes instead of presentation oriented classes. Compass has ports Frameworks like Blueprint, YUI, 960.gs, as well as even some Compass only ones like Susy. On top of that, there are also loads of extensions to Compass for everything from CSS3 button generators to more complex sprite and image generators.
