The conference is unfortunately canceled

There will be no Fronteers Conference this year.

With a very heavy heart, we have to inform you that we aren't able to hold our 14th conference.

Despite a big marketing push in the last few weeks, we didn't manage to sell enough tickets to make it possible for us to hold this year's conference. The financial risk would have been too big.

For everyone who did buy a ticket: thank you so much for your support! We are very sorry that we can't keep our side of the deal. You will be refunded as soon as possible.

What this means for the future of the Fronteers Conference we don't know. If something changes we will definitely let you know.

Lea Verou - A story of ice, fire, and CSS Nesting 🧊🔥🪆

You may have heard that native CSS Nesting is shipping at a browser near you. You may even have heard that the syntax has changed a fair bit over time, even if you’re fuzzy on the details. This talk will take you backstage and show you how the sausage is made: the trials and tribulations of designing a syntax that balances developer experience, with performance and implementability. Yes, you will learn CSS Nesting in great depth, but this is a talk as much about CSS as it is about the human dynamics of developing languages, products, and APIs that involve cross-functional teams from different organizations, and the many trade-offs and decisions that have to be made before shipping features to the millions of developers worldwide.

Lea Verou has been working on improving the Web for over a decade, from many angles. She helps move Web technologies forwards, as an elected W3C Technical Architecture Group (TAG) member, and as a longtime CSS Working Group Invited Expert and co-editor of several CSS specs. She currently works at MIT, doing research at the intersection of usability and programming languages and intermittently teaching these topics. She is a well known speaker and author, having written several articles, book chapters, and the bestselling advanced CSS book CSS Secrets. Lea has also started several open source projects and web applications, such as Prism, Mavo, and Awesomplete. Her open source work is used on millions of websites. She tweets @leaverou and blogs at She holds a MSc in Computer Science from MIT. Despite her technical pursuits, Lea is one of the few misfits who love code and design equally.
