A CSSful Quest

User-friendly products are apparently popular, so it’s up to you and our designer to make ours friendlier. In this quest, you will practice implementing a new design element in the application’s UI. Using CSS, you will customize the look and feel for mobile users. You will also work with the designer to identify possible edge cases and ensure a seamless user experience for all devices.

"Segment is an infrastructure-type tool that can be hard to demo without having other components present. Wilco's quest builder makes it easy to have those components preconfigured so that the prospective customer can jump right into the learning rather than spending a lot of time fiddling with environmental quirks. Wilco was a great fit for us at Segment because it neatly wraps the whole developer experience.”
