Understanding -sd-animation: sd-fadeIn; –sd-duration: 250ms; –sd-easing: ease-in;

This short CSS declaration group is a compact pattern for applying simple, reusable animations via custom properties and a small naming convention. Below is a clear explanation of each part, how they work together, and a minimal implementation you can use or adapt.

What each property does

• -sd-animation: names the animation preset to apply (here sd-fadeIn), typically used by your stylesheet or JS to select an animation pattern.
• –sd-duration: sets the animation duration (here 250ms).
• –sd-easing: sets the timing function (here ease-in).

Example: CSS setup and usage

Define base animation keyframes and a rule that maps the -sd-animation name to actual animation properties via custom properties:

:root {–sd-duration: 250ms;  –sd-easing: ease-in;}
/* Example keyframes /@keyframes sd-fadeIn {  from { opacity: 0; transform: translateY(6px); }  to   { opacity: 1; transform: translateY(0); }}
/ Rule to apply the chosen animation name via the custom property
