This is a simple page that renders a list of 10 items. Try it with and without JavaScript enabled in your browser.

The Design System Ecosystem
What does a mature, end-to-end design system look like in a big, complex organization? What are all the moving pieces, and how do they hang together as a well-considered architecture? What’s required and what’s optional? Hold onto your butts, because we’re going to go deep on this one.

The failed promise of Web Components • Lea Verou

Remember how exciting it was every time we got new shiny HTML elements that actually do stuff? Remember how exciting it was to be able to do sliders, color pickers, dialogs, disclosure widgets straight in the HTML, without having to include any wi
Introducing: Modern Web

The Power of Web Components – Mozilla Hacks - the Web developer blog
Background Ever since the first animated DHTML cursor trails and “Site of the Week” badges graced the web, re-usable code has been a temptation for web developers. And ever since those heady days, integrating third-party UI into your site has been, well, a semi-brittle headache. Using other people’s clever code has required buckets of boilerplate JavaScript or CSS conflicts involving the dreaded !
