<script type="module">
  import 'lion-icon/lion-icon.js';
  import bugSvg from '../icons/bug.svg.js';
</script>

Use it in your lit-html template:

<lion-icon .svg=${bugSvg}></lion-icon>

By default, a lion-icon will be 1em × 1em (the current line-height).

A lion-icon may be styled like a regular HTML element:

<style>
  lion-icon.big {
    width: 3rem;
    height: 3rem;
  }
</style>

SVG Styling

lion-icon uses SVGs and may be styled with CSS, using CSS properties such as fill and stroke:

<style>
  lion-icon.strong {
    fill: azure;
    stroke: lightsteelblue;
  }
</style>
<lion-icon .icon=${arrowSvg} class="strong"></lion-icon>
