Here’s a nice HTML web component that uses structured data in the markup to populate a Leaflet map.
Personally I’d probably use microformats rather than microdata, but the princple is the same: progressive enhancement from plain old HTML to an interactive map.
This looks like a handy collection of HTML web components for common interface patterns.
drab does not use the shadow DOM, so you can style content within these elements as usual with CSS.
Scott has written a perfect description of HTML web components:
They are custom elements that
- are not empty, and instead contain functional HTML from the start,
- receive some amount of progressive enhancement using the Web Components JavaScript lifecycle, and
- do not rely on that JavaScript to run for their basic content or functionality.
The main reason I’m so hot on Light DOM is that I find the styling story of Web Components using Shadow DOM annoying.
Here’s the video of the talk I gave in Nuremberg recently.
You might want to use `display: contents` …maybe.
A lazy option for responsive images is at hand.
If the JavaScript API requires a user gesture, maybe it’s time for a new button type.
Pushing for a share button type—the story so far…
It’s not because it’s declarative—it’s because it’s robust.
