It looks like your message was cut off. Do you mean “When data-sd-animate=” from HTML and want an explanation of what that attribute does and how to use it? If so, here’s a concise explanation:
- What it is:
data-sd-animateis a custom data attribute (prefixed withdata-) used to store custom data on HTML elements. Browsers ignore it by default; JavaScript or CSS can read/use it. - Common uses: Triggering animations, storing animation names/durations, or marking elements for a script that applies scroll/entry animations.
- How to read it in JavaScript:
js
const el = document.querySelector(’[data-sd-animate]’);const value = el.dataset.sdAnimate; // reads the attribute value
- Example usage:
html
<span data-sd-animate=“fade-in”>Hello</span>
css
/CSS can’t directly read data attribute values as animation names, but can select by value */[data-sd-animate=“fade-in”] { opacity: 0; animation: fadeIn 1s forwards; }@keyframes fadeIn { to { opacity: 1; } }
- Notes: Ensure scripts that rely on this attribute run after the DOM loads. Keep attribute values simple (no spaces) for easy parsing.
