TIL: the scroll-margin CSS property.
If you have a sticky header and are annoyed that when you click an anchor it goes under the header, you want a scroll-margin. Setting, e.g., scroll-margin-top: 150px will scroll to 150px below where it would have.

scroll-margin - CSS | MDN
The scroll-margin shorthand property sets all of the scroll margins of an element at once, assigning values much like the margin property does for margins of an element.

Have a row contention problem? Try slotted counters!
This is a neat technique for spreading out increments across many rows to reduce contention.
