Understanding ”-sd-animation: sd-fadeIn; –sd-duration: 0ms; –sd-easing: ease-in;”

These CSS-like custom properties appear to be a small snippet defining an animation behavior using vendor- or project-specific variables. Below is a concise explanation and practical guidance for using and adapting them.

What each part means

• -sd-animation: sd-fadeIn;
  • Assigns a named animation token (likely defined elsewhere) that triggers a fade-in effect.
  • The -sd- prefix suggests a custom namespace (library, framework, or design system).
• –sd-duration: 0ms;
  • Defines the animation length; 0ms means the animation runs instantly (no visible transition).
• –sd-easing: ease-in;
  • Sets the timing function controlling acceleration; ease-in starts slow and speeds up.

Likely usage

This snippet is intended to be used with CSS that reads these variables, e.g.:

.element {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); }}

Why duration is 0ms

• With 0ms, the fade-in is effectively disabled; useful for:
  • Reducing motion for accessibility (or when motion should be suppressed).
  • Instant state changes while keeping the same CSS tokens for consistency.
• To enable a visible fade, set a positive duration (e.g., 200ms, 350ms).

Accessibility considerations

• Respect user motion preferences:

@media (prefers-reduced-motion: reduce) {  :root { –sd-duration: 0ms; }}

• Provide focus-visible styles separate from animation so keyboard users aren’t disadvantaged.

Recommendations

• Use consistent variable names across your design system (e.g., –sd-animation, –sd-duration).
• Expose sensible defaults (e.g., 200ms, ease-out) and allow overrides per-component.
• Document tokens and include both animated and instant variants for testing/dev modes.

Example practical variants

• Smooth fade:

:root { –sd-duration: 200ms; –sd-easing: ease-out; -sd-animation: sd-fadeIn; }

• Instant/no-motion:

:root { –sd-duration: 0ms; –sd-easing: linear; -sd-animation: none; }

Use these tokens to keep animation behavior consistent and easily adjustable across your project.
