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

This article explains the CSS-like custom properties shown in the title, what they do, how and when to use them, and practical examples for implementation.

What these properties represent

• -sd-animation: A custom CSS property intended to select a predefined animation (here, sd-fadeIn).
• –sd-duration: Duration of the animation (0ms in the title, meaning instantaneous).
• –sd-easing: The timing function that controls animation pacing (ease-in here).

These look like CSS custom properties (CSS variables). They may be used by a framework or component library that reads these variables and applies corresponding animations via standard CSS or JavaScript.

Typical use cases

• Allowing component-level customization of animations without modifying stylesheet code.
• Templating systems where animations are chosen dynamically.
• Theme variables for consistent motion design across an app.

How they might be implemented

1. Define the animation keyframes and a mapping from -sd-animation values to actual animation names:

@keyframes sd-fadeIn {from { opacity: 0; transform: translateY(8px); }  to { opacity: 1; transform: translateY(0); }}:root {  –sd-duration: 200ms;  –sd-easing: ease-out;}

2. Apply the variables in a component:

.component {  animation-name: var(–sd-animation, none);  animation-duration: var(–sd-duration, 200ms);  animation-timing-function: var(–sd-easing, ease-out);  animation-fill-mode: both;}

3. Override per-instance:

<div class=“component” style=”–sd-animation: sd-fadeIn; –sd-duration: 150ms; –sd-easing: ease-in;”></div>

Why –sd-duration: 0ms might be used

• To disable animations conditionally (e.g., reduce motion for accessibility or initial render).
• To create instant state changes while preserving a single code path for animation handling.

Accessibility considerations

• Respect user preference for reduced motion (prefers-reduced-motion).
• Provide sensible default durations and avoid jarring movements.

Example:

@media (prefers-reduced-motion: reduce) {  .component { animation-duration: 0ms !important; }}

Debugging tips

• Verify the custom property name matches what the framework expects (note leading dash vs double-dash).
• Check cascade/priority—inline styles override external stylesheets.
• Ensure animation keyframes exist and animation-name receives the correct value.

Conclusion

Using custom properties like -sd-animation, –sd-duration, and –sd-easing offers flexible, per-component animation control. Ensure correct naming, provide fallbacks, and consider accessibility to make animations smooth and user-friendly.
