rerenders

rerenders() injects an adopted stylesheet that flashes every element with a blue background whenever it rerenders — a drop-in visualiser for render thrashing. The flash is a one-second CSS animation that runs each time an element is (re)created and enters the DOM; the stylesheet is adopted on document, so call it once and watch the page. Part of pota/use/test.

Arguments

Takes no arguments.
