How to create Liquid Glass effects with CSS and SVG

Apple's Liquid Glass UI, introduced in iOS 26, enhances the Glassmorphism trend by adding more realistic optical effects like refraction and reflection, which are achieved through a sophisticated rendering engine on iOS. Developers are now exploring ways to replicate these effects on the web using SVG filters, despite the absence of native browser support for such abstractions. A detailed tutorial walks developers through building a Liquid Glass button in React, utilizing SVG filters, Tailwind CSS, and Figma for asset creation. It covers the principles of refraction and reflection, performance trade-offs, browser compatibility, and accessibility concerns. While Liquid Glass offers a visually striking aesthetic, it comes with challenges such as high resource consumption on GPUs and limited browser support, necessitating its use in carefully chosen, high-impact UI elements to maintain accessibility and performance.
