Fade In Up

The text rises a little as it fades in. The most useful entrance animation there is: quiet, quick, and appropriate for headings, captions and anything that appears on load.

Also known as: text fade in, fade up on load, entrance animation.

@media (prefers-reduced-motion: reduce) {
  .txt-fade-up, .txt-fade-up *, .txt-fade-up::before, .txt-fade-up::after {

Customizing this snippet

  • Color: set --txt-color on the element or a parent. Currently previewing #3b82f6.
  • Font size: set --txt-size. Every other dimension is in em, so the whole thing scales together. Currently previewing 40px.
  • Speed: change the duration on the transition or animation shorthand. Staggered delays are relative, so they keep their rhythm.
  • Reduced motion: the rule at the end of the CSS turns the motion off for people who asked their OS for less of it. Keep it.
