Most of the work here has been done in #47. See that PR for testing instructions. The current test runner is QUnit, but we don't have D3-specific tests yet. The...

Some more tests to include: - [x] test classList shim on SVG elements (see: WebReflection/dom4#10) - [ ] events: at the very least, we should check that HTML elements have...

Hi, I'm actually a huge fan of @WebReflection and have used his v0 polyfill extensively! However, to more closely align with what my teammates at GitHub are doing, I decided...

Also, sorry for not responding to your question, @joshbruce! My personal preference (and one that I've raised in 18F/web-design-standards#1526) is to use the HTML standard elements whenever possible, and deploy...

@areinot As far as I know, there's no prohibition on inline event handlers in the [custom elements v1 spec](https://www.w3.org/TR/custom-elements/), so they _should_ work. [Your example works](https://jsfiddle.net/r0gp6Lz8/) in Chrome's native implementation...

One way that we could handle this is to have one or more variables where the URLs of certain images live, so that non-github — or even just uses outside...
