These look like CSS custom properties used to control a reusable animation. Brief breakdown:
- -sd-animation: sd-fadeIn;
- Likely a custom shorthand property indicating which animation to apply (here, “sd-fadeIn”).
- –sd-duration: 0ms;
- Animation duration; 0ms means the animation runs instantly (no visible transition).
- –sd-easing: ease-in;
- Timing function controlling acceleration; “ease-in” starts slowly and speeds up.
Notes and quick usage example:
- If the duration is 0ms the easing has no visual effect; set a positive duration (e.g., 300ms) to see the fade.
- The animation name (sd-fadeIn) must correspond to a keyframes rule or a CSS animation implementation that reads these custom properties.
Example CSS pattern:
css
.element {–sd-duration: 300ms; –sd-easing: ease-in; -sd-animation: sd-fadeIn; animation-name: var(-sd-animation); animation-duration: var(–sd-duration); animation-timing-function: var(–sd-easing); animation-fill-mode: both;}
@keyframes sd-fadeIn { from { opacity: 0; transform: translateY(8px); } to { opacity: 1; transform: translateY(0); }}
Adjust duration and easing as needed.
