Ben Orenstein is joined by Kyle Fiedler, a designer at thoughtbot, and one of the creators of Bourbon Neat. Ben and Kyle discuss responsive design, what it is, and how to implement it. They also discuss Bourbon (a library of Sass mixins) and Neat (a fluid grid framework based on Bourbon), what's wrong with Twitter Bootstrap and why Bourbon Neat is better, and the other reasons why Bourbon Neat was created despite all the other grid frameworks that are available. Kyle shares the most common design mistakes he sees developers make in projects, whether or not design is subjective or whether it can be more objective, his design process and how it has changed, what the Golden Ratio is, and how it's used in Neat. Finally, they also discuss the Design for Developers workshop offered by thoughtbot, which teaches the fundamental design principles and tools to developers, and much, much more.
