Safari Technology Preview 185 is here! With exciting news…

We’ve added a switch control to the web, with `<input type="checkbox" switch>`, so you don’t have to hack a checkbox with custom styling to make it look like a switch! By building on top of checkbox, it falls back nicely in browsers without support.

We’ve got support for `align-content` on block containers — which means you’ll be able to vertically center anything (or `end` align), not just Flexbox/Grid items!
