## Heading anchors

Links with `href="#..."` inside headings are automatically displayed as anchors:

<article>
  <h2 style="margin: 0 0 0 1.5rem">Heading with anchor <a aria-hidden="true" style="visibility: visible">#</a></h2>
</article>

How it works:
```css */
h1,
h2,
h3,
h4,
h5,
h6 {
  position: relative;

  a[aria-hidden="true"] {
    position: absolute;
    right: 100%;
    top: 50%;
    transform: translateY(-50%);
    padding-right: 0.2ch;
    color: silver;
    text-decoration: none;
    visibility: hidden;
  }
  @media /* to avoid double-tap on touch devices */ (hover: hover) {
    &:hover {
      a[aria-hidden="true"] {
        visibility: visible;
      }
    }
  }
}
