Loader

<auro-loader> is a HTML custom element for the purpose of illustrating animated loaders.

Things take time. Sometimes we just need to take a second for some data to show up. For this Auro supports the <auro-loader> custom element. This powerful element supports multiple modes for use, ringworm, orbit, pulse, and laser.

And each of these modes support five size settings, default, sm, md, lg, and xl.

For color support <auro-loader> supports currentColor, this allows for any color set on the parent element to influence the color of the loader.

The <auro-loader> custom element also supports two pre-defined color modes: onlight and ondark.
