winzig / Liberal Regex Pattern for URLs
Last active July 30, 2024 22:09 — forked from gruber/Liberal Regex Pattern for Web URLs
Updated @gruber's regex with a modified version that looks for 2-13 letters rather than trying to look for specific TLDs, and many other improvements. (UPDATE 2018-07-30: Support for IPv4 addresses, bare hostnames, naked domains, xn-- internationalized domains, and more... see comments for BREAKING CHANGE.)

A simple Sass function for frame-based CSS animation

A simple Sass function for frame-based CSS animation

If you have experience with animation in other media, CSS animation’s percentage-based keyframe syntax can feel pretty alien, especially if you want to be very precise about timing. This Sass function lets you forget about percentages and express keyframes in terms of actual frames:

@function f($frame) {
  @return percentage( $frame / $totalframes )
}
