Refactoring CSS Without Losing Your Mind

by Harry Roberts

Working with CSS is tricky enough as it is: working with legacy CSS can be nightmarish. In this talk, we’ll look at how we decide what to refactor and when; how we can refactor code whilst still shipping features; how to avoid regressions when adding new CSS; how we can avoid the dreaded refactoring tunnels; running new and legacy code in tandem; and a bunch of other neat little tips and tricks.


Alice in Web Animations API Land

by Rachel Nabors

Animation is back in the web development tool chest! We know of declarative CSS Animations and Transitions and fully featured JavaScript animation libraries like GreenSock, but there's a third, dynamic option: the Web Animation API! In this talk Rachel will take you on a magical journey with Alice from Wonderland to show you how this new API is used to run the CSS Animations in your browser and how you can use it to generate and manipulate animations in your project. Colorful, interactive, useful fun for all disciplines.


CSS Grids or: How I Learned to Stop Worrying and Love the new spec

by Ariel Wiznia

Struggling with tables? With floats? An impossible to replicate with CSS? No more! with the advance of new spec for grids you'll be able to create impossible, responsive and structures quickly and easily.


Practical Blend Modes

by Una Kravets

With the availability of SVG and CSS filters and blend modes, our browsers have become very powerful image rendering engines. From creating faux surrealist effects to 3D images, the artistic possibilities are endless. But how can we integrate filters and blend modes into UI elements? How can we use them in our every day user interfaces to improve performance and aid in design? This talk will cover just that, and show some practical examples of using filters and blend modes.


Building and maintaining messenger.com

by Horia Dragomir

Horia’s talk tells the story of building and maintaining messenger.com. Horia will give us a glimpse into how CSS is used at Facebook, and how it worked both for and against the developers tasked with working on the first secondary domain: messenger.com. Contains cool CSS and a bit of React. You’ve been warned!


Slippy Map Style: Geo-canvas design with CartoCSS

by Aurelia Moser

Maps provide us with some of the most intuitive ways to represent data visually, principally because they allow us to rectify our physical locality with some digital and data-dense topography. We build mythologies with maps: stylized captures of how we might see the world. This talk will go over how we might creatively style maps, and build mythology with integrity and pure CartoCSS.


Game Dev for Web Designers: Play with the DOM like you never did before!

by Werther Azevedo

Have you noticed how hot a trend is Web Animations right now? That's because browser vendors are optimizing their Javascript engines like crazy to make the DOM faster and provide native-like user experiences. Do you know what this also means? That nowadays there's a bunch of fun video games you can develop using your dear, trusted DOM toolset! In this talk, we'll explore the types of games suited for this development paradigm, and go through some techniques using jQuery, GSAP and good ol' CSS!


What NOT to do in CSS

by Sergio Behrends

Having some fun with common CSS mistakes and 10 common errors we must not do.


Speed up! Critical CSS to the rescue

by Ami Reynoso

We all know a fast loading website equals happy users. But, how much are we doing as developers to reach this goal? By only optimizing some things here and there, we can accelerate the loading time of our website almost effortlessly. In this talk I’ll show you how we can adopt the Critical CSS technique in our projects in an easy way, and also go through our experience on implementing it at Mercado Libre.
