It looks like your snippet is incomplete: “ data-sd-animate=” is the start of an HTML span element with a custom data attribute but missing the attribute value, closing bracket, and any content. Here’s what it likely is and how to use it.
What it is
- It’s an HTML span element with a custom data attribute named data-sd-animate, commonly used to mark elements for JavaScript-driven animations.
How to complete and use it
- Add an animation name or config as the attribute value:
- Example: Animated text
- Add CSS to define a base state (optional):
- Example:[data-sd-animate=“fade-in”] { opacity: 0; transition: opacity 0.5s ease; }
[data-sd-animate=“slide-up”] { transform: translateY(10px); transition: transform 0.4s ease; }
- Example:[data-sd-animate=“fade-in”] { opacity: 0; transition: opacity 0.5s ease; }
- Use JavaScript to trigger the animation (on load, scroll, hover, etc.):
- Example:
Common patterns for the attribute value
- Single token names: “fade-in”, “slide-up”, “pop”, “zoom”.
- JSON-like config for complex behaviors: data-sd-animate=‘{“type”:“fade”,“delay”:200}’ (requires parsing in JS).
Accessibility tips
- Ensure animations don’t interfere with readability.
- Honor prefers-reduced-motion: skip nonessential animations if user prefers reduced motion.
If you want, I can:
- Provide complete example markup/CSS/JS for a specific animation type.
- Explain how to parse JSON config values in data attributes.
- Show how to integrate with animation libraries (GSAP, Anime.js).
