Lea Verou (@leaverou) is one the most prolific conference speakers on CSS, and for good reason: she’s an invited expert of the CSS Working Group, was part of the W3C team contributing to the WebPlatform.org project, and has spent years sharing her CSS knowledge as articles, open-source tools and presentations.

Lea’s in-depth knowledge, passion for sharing, and practical experience was what had us excited to bring her to CSSConf Australia. And it was her CSS3 Patterns Gallery that gave me my first glimpse into the untapped power of CSS.

Some of her many open-source projects include:

• Prefix Free - a Javascript library enabling you to write CSS without developing vendor-prefix-induced RSI
• Prism - a modern, lightweight, syntax highlighter framework (as used on the MDN developer docs)
• Dabblet - a site for testing and sharing snippets of CSS
• cubic-bezier.com - a tool for creating and sharing CSS animation timing functions
• DPI love - “more than you probably wanted to know about DPI”
• Contrast Ratio - a tool for checking foreground/background colour contrast as per WCAG 2.0
• Animatable - a demonstration of animating each animatable CSS property
• And more at github.com/leaverou and lea.verou.me/projects

If you’re not already coming, don’t miss the chance to see Lea Verou speak, and grab one of the few remaining late bird tickets before they sell out.
