One way to remove multi–page transition jank is to force a permanent scrollbar. Are there any kindred spirits? Yes — there’s a kindred spirit. Overflows may disable descending position: sticky behavior. Avoid that problem with other jank removal techniques.

html {
  overflow-y: scroll;
}

body {
  overflow-y: scroll;
}

Whenever I’m handcrafting CSS, content selection rules are usually the first declarations on my sheet. Might as well ensure user selected text is readable. Easiest win for accessibility.

::selection {
  color: #fff;
  background-color: #000;
}

::-webkit-selection {
  color: #fff;
  background-color: #000;
}

::-moz-selection {
  color: #fff;
  background-color: #000;
}
