## Code

```css
#comments,
.comments-area,
.wp-block-comments,
.site-footer,
footer.wp-block-template-part,
.related-posts,
.jp-relatedposts {
    content-visibility: auto;
    contain-intrinsic-size: auto 800px;
}
```

## Notes

Adjust the selectors to your theme; the size hint keeps the scrollbar from jumping.
