Custom Elements need clear and parsable API documentation.
I like Web Components. It has taken a long time to get here but things are moving in the correct direction with Safari shipping Shadow DOM and now landing support for Custom Elements. I’ve been thinking a lot recently about Web Components, that is custom elements, template, Shadow DOM and CSS variables, specifically I have been focusing some of my thoughts on custom element space and how this can play out on the web in the future because I believe there are lots of interesting possibilities with how the usage of them will evolve over time.
