Reusable CSS/HTML widgets
I would like to see some episodes on building modular CSS/HTML components. Not necessarily "web components", but a re-usable element I could use in multiple projects. For instance, there are lots of datepickers out there, but I always end up having to customize them. It would be nice to know how to write my own and not have to rely on others. Even though I'm a Rails developer, I probably spend 75% of my time on the front-end interfaces.
