💡 Usage

Use CSS Houdini API to import the fractals.js file

// Modern Browsers - Import JavaScript file from CDN
if ('paintWorklet' in CSS) {
    CSS.paintWorklet.addModule('https://unpkg.com/css-houdini-fractals@1.0.0/fractals.js');
}

// Modern Browsers - Using Local build, only a single file is needed
if ('paintWorklet' in CSS) {
    CSS.paintWorklet.addModule('fractals.js');
}

Use the css-paint-polyfill Polyfill to support all Modern Browsers (won't work with IE)

https://github.com/GoogleChromeLabs/css-paint-polyfill

<script type="module">
    (async function () {
        if (CSS['paintWorklet'] === undefined) {
            await import('https://unpkg.com/css-paint-polyfill');
        }
        CSS.paintWorklet.addModule('fractals.js');
    })();
</script>

HTML

The type of HTML element and class name does not matter, rather height and width are needed.

<style>
    .fractals { height:400px; width:400px; }
</style>
<div class="fractals"></div>
<section class="fractals"></section>

CSS Options

/*
    By default only `background-image: paint(fractals)` is needed.
*/
.fractals {
    background-image: paint(fractals);
}

/*
    The example below shows all options with default values, except
    for [--colors] which is empty resulting in black lines.

    [--colors] are dynamic and based on the number of colors included.
    The delimiter for [--colors] is a space so these examples are all valid:
        --colors: red green blue;
        --colors: black;
        --colors: #000 #222 #444 #666 #888 #aaa #ccc;

    [--shape] = One of [line, circle, square]
    [--debug-to-console] and [-show-origin] = 0 or 1
*/
.fractals {
    --colors: red green blue cyan magenta yellow;
    --angle: 30;
    --starting-length-percent: 22;
    --next-line-size: 0.8;
    --shape: line;
    --max-draw-count: 10000;
    --debug-to-console: 0;
    --show-origin: 0;
    background-image: paint(fractals);
}
