At thoughtbot we love sharing what we know. Our Design team has put together a new series to teach a technique or best practice in a bite-sized lesson. Each video is only about 5 minutes long and shows you step by step how tos in CSS, Sass, etc.
Follow thoughtbot on LinkedIn and Twitter to see new videos drop periodically and browse the entire collection in the Design Bites Playlist.
If we can help you with product design and development, get in touch here.
