/**
 * Provides better intellisense for JSX Components at call-site by allowing them to accept additional generics.
 *
 * In some cases it also switches `onChange` handler from `(value: string) => void` to `(event: HTMLInputEvent<..>) => void`
 * to be used with `useFormState()` hook's e.g. `onInputChange` which accepts `EventStub` (`(ev: { target: { name, value }}) => void`).
 *
 * @example
 * interface FormState {a, b}

This is a simple Tailwind plugin to expose all of Tailwind's colors, including any custom ones, as custom css properties on the :root element.

There are a couple of main reasons this is helpful:

• You can reference all of Tailwind's colors—including any custom ones you define—from handwritten CSS code.
• You can define all of your colors within the Tailwind configuration, and access the final values programmatically, which isn't possible if you did it the other way around: referencing custom CSS variables (defined in CSS code) from your Tailwind config.

See the Tailwind Plugins for more info on plugins.

How to transform an SVG into a data URI

by Jenny Knuth, based on the work of Chris Coyier and Taylor Hunt

A data URI is a nice way to include a web resource without needing to make an HTTP request. Chris Coyier explains the technique nicely in Probably Don't Base64 SVG.

While a PNG might use Base64 encoding, for SVG, there is a better way.

Taylor Hunt's experiments led to this solution for optimizing SVGs in data URIs:

"So the best way of encoding SVG in a data URI is data:image/svg+xml,[actual data]. We don’t need the ;charset=utf-8 parameter (or the invalid ;utf8 parameter…), because URLs are always ASCII."

Spoiler warning

Spoiler text. Note that it's important to have a space after the summary tag. You should be able to write any markdown you want inside the <details> tag... just make sure you close <details> afterward.

console.log("I'm a code block!");
