GSS - CSS Layout from the Future

CSS layout is broken. Even with Flexbox, simple layout changes can still require deep changes to the underlying HTML and CSS. Existing CSS primitives are simply not expressive enough to describe basic relational layouts like aligning sibling elements with each other.

GSS (Grid Style Sheets) introduces a set of tools for creating relational layouts in CSS using a syntax inspired by the success of Apple's Cocoa Autolayout for iOS and OS X. Powered by the Cassowary Constraint Solver, a constraint-based layout algorithm, GSS allows highly complex layouts to be described in just a few simple lines of enhanced CSS.

In this talk, we'll dive into the magic of GSS and how it can be used to make your layouts simpler and more powerful.

Mike Petrovich (@mikepetrovich) leads front-end engineering at Next Big Sound where he current hacks AngularJS, CSS, and end-user performance.

    I just gave up my seat. I didn't realize this was in BK. I love BK but couldn't make it in time. Plus, I just got a ton of work dumped on me plus a presentation to do as soon as i get into work tomorrow.

    Sadly, I've made other plans and can't attend. I'm hoping the talk will be recorded. Please let us know. Thanks!

    Although I would very much like to attend this, I needed to change my RSVP to no. I work in Connecticut & I foresees not making it on time to Brooklyn on that day after work. I will continue to look out for events and I'm definitely interested in participating in the next one.

      I wonder if you ever schedule events around upper east side or upper west side? What type of locations r u looking for? Court Houses have nice size space. I've been to a coding meetup in a CT courthouse.

    I can't make this meetup but my biggest concern with GSS is the amount of browsers that support it. I guess this will be talked about during the meetup. I'm hoping their will be slides for those who can't make it.

    Hello, I RSVP'd yes to this event, as I want to participate, but I'm curious about location. I work in Connecticut and I finish between 5-6 pm. I'm trying to plan for timing @ location.
