These are CSS custom properties (CSS variables) used to configure a scoped animation. Explanation:
- –sd-animation: sd-fadeIn;
- Defines the animation name or preset. Here it likely references a keyframes rule or a named animation preset called “sd-fadeIn” (a fade-in effect).
- –sd-duration: 0ms;
- Sets the duration of the animation. 0ms means the animation runs instantly (no visible transition).
- –sd-easing: ease-in;
- Sets the timing function for the animation; “ease-in” starts slow and speeds up.
How they’re typically used (example):
.element {animation-name: var(–sd-animation, none); animation-duration: var(–sd-duration, 300ms); animation-timing-function: var(–sd-easing, ease);}
Notes:
- With duration 0ms the easing has no visible effect because there’s no time to interpolate.
- Ensure the referenced animation (sd-fadeIn) is defined with @keyframes or provided by a framework.
