It’s kinda neat how CSS animation rules are sort of simple in their construction. imo, rules could be made even simpler if the animation-delay property also allowed delays between iterations/intervals instead of at the start only. Interval delays could allow for writing drastically less key frame rules.

text-animation[hang] {
  animation: tilt-rightward 1.3s infinite, tilt-leftward 1.8s infinite;
}

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;
}

Browsers are on a slow march towards fully adopting user options for standardized/algorithmic color stylesheets. Great debates over what color to paint the bike shed (website) will eventually end. Paint it (mostly) whatever color you want.

In addition to the invert filter, another way of quickly bootstrapping a dark mode CSS stylesheet is to use Chromium’s auto dark mode emulation as an initial reference.

Firefox’s developer tools excel at finding and fixing accessibility problems quickly. For example, to find all contrast issues on a page fire up the accessibility inspector and scan the DOM tree. My favorite developer tools? You guessed it — Firefox.

The CSS flexible box layout (flexbox) is a great spec. The flex-direction property allows rearranging the position of children inside a flex container. This works in pretty much every browser — even defunct ones like Internet Explorer. Don’t work hard and write JavaScript, be lazy and write CSS.

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;
}
