You included an incomplete HTML snippet: Use . Likely you’re asking what the attribute does and how to use it. Here’s a concise explanation and examples.
What it is
- data-sd-animate is a custom data attribute (prefixed with
data-) used to store animation-related information on an element. The browser ignores it by default; JavaScript or CSS reads it to apply behavior.
How it’s commonly used
- Toggle or configure animations via JS: read the attribute value to choose an animation type, duration, or trigger.
- Hook for animation libraries: a script scans for
[data-sd-animate]elements and initializes animations. - Store state or parameters without polluting global JS variables.
Typical attribute values
- A single token:
data-sd-animate=“fade-in” - Multiple params (JSON or space/comma-separated):
data-sd-animate=“fade-in 500ms delay:100ms”or `data-sd-animate=‘{“type”:“fade”,“duration”:500}’
Examples
- Simple JS-triggered animation
html
<button id=“btn” data-sd-animate=“slide-up”>Show</button><div id=“panel” data-sd-animate=“slide-up”></div>
<script>document.querySelectorAll(’[data-sd-animate]’).forEach(el=>{const type = el.dataset.sdAnimate; // “slide-up” // simple example: add a class matching the type el.classList.add(type);});</script>
- JSON params
html
<div data-sd-animate=’{“type”:“fade”,“duration”:300,“delay”:100}’></div>
<script>const cfg = JSON.parse(document.querySelector(’[data-sd-animate]’).dataset.sdAnimate);el.style.transitionDuration = cfg.duration + ‘ms’;setTimeout(()=> el.classList.add(‘fade-in’), cfg.delay);</script>
- Using with an animation library (conceptual)
- A library might read
data-sd-animate=“zoom”and call its animation API to run a “zoom” effect when the element enters the viewport.
Best practices
- Keep values simple or use JSON when you need multiple params.
- Sanitize/validate JSON if it’s user-supplied.
- Prefer CSS classes for purely visual effects; use data attributes as configuration hooks.
- Document supported attribute values for maintainability.
If you want, I can:
- Show a runnable example that animates on scroll.
- Suggest CSS animations for specific effects (fade, slide, zoom).
