The plugin takes a no-frills, zero-config approach – you simply activate the plugin, and it just works – thanks to the excellent underlying web component implementation. There should be no notable adverse effects on performance, also given the plugin uses the <a href="https://make.wordpress.org/core/2024/03/04/script-modules-in-6-5/" rel="nofollow ugc">WordPress Script Modules API</a> that was introduced in WordPress 6.5.
The plugin respects user preferences for reduced motion, as a best practice for accessibility.

Flurry adds a falling snow effect to your WordPress site. It uses the <a href="https://github.com/joshmcrty/flurry" rel="nofollow ugc">Flurry jQuery plugin</a> to create the effect. <a href="https://cdn.rawgit.com/joshmcrty/Flurry/master/index.html" rel="nofollow ugc">See an example</a>.
The Flurry jQuery plugin takes advantage of CSS <code>transforms</code>, CSS <code>transitions</code> and <code>requestAnimationFrame</code> to provide smooth animation for modern browsers. It uses unicode characters as snowflakes, with no dependencies on images or CSS files. Polyfills are automatically provided for <code>requestAnimationFrame</code> and CSS <code>transitions</code> (falling back to <code>setInterval</code> and jQuery’s <code>.animate()</code> feature respectively) for excellent browser compatibility. See the <a href="https://github.com/joshmcrty/flurry" rel="nofollow ugc">Flurry website</a> for more information.
