A ui framework where you only write turing complete CSS. No HTML, no JS, no build system.

Disclaimer: Don't use this

Usage

Add script tag to the renderer to your html

<script async defer src="https://unpkg.com/@css-everything/render/dist/renderer/index.js"></script>

Open up a style tag or link a stylesheet

The renderer by default uses the body element. You can use :root to describe the starting point. Here's a simple counter example:

:root {
  --counter: '0';
  --cssx-children: div#count button#decr button#incr;
}

#count::after { content: "Count: " var(--counter); }

#incr {
  --cssx-on-click: update(':root', --counter, calc(get-var(--counter) + 1));
  --cssx-text: "++";
}
#decr {
  --cssx-on-click: update(':root', --counter, calc(get-var(--counter) - 1));
  --cssx-text: "--";
}

What time is it?

You can find the answer with this example.

How does it work?

Here's how it works.

Is this turing complete?

Yep. Not that you asked, but here's how to calculate factorial of a number.

:root { --cssx-children: div#container; }

#container {
  --factorial: func(--n: number)
    if(lte(get-var(--n), 1), 1,
      calc(
        get-var(--n)
        * call(--factorial, map(--n: calc(get-var(--n) - 1)))
      ));

  --cssx-text: string("7! = ", call(--factorial, map(--n: 7)));
}

Escape hatches?

• If you want to directly render some raw html, you can use --cssx-disgustingly-set-innerhtml.
• If you want to run js expressions, you can use the js-eval function. Eg: js-eval("new Date().getSeconds()")

Does it need a build step?

No. In fact, this'll probably break if you try to use it with a css preprocessor.
