Innovative Liquid Glass Effect Using Pure HTML and CSS Techniques
In the realm of web design, achieving realistic glass-like visual effects has always been a challenging pursuit. Today, I’d like to share a proof-of-concept that approximates the coveted “liquid glass” appearance using only HTML and CSS — no JavaScript or external libraries involved.
A Visual Demonstration
This effect leverages the longstanding SVG filter specifications, repurposed as a custom backdrop filter with url(#svgFilter). While experimental, it offers a fascinating glimpse into what is possible within the current capabilities of standard web technologies.
How It Works
At its core, this technique applies a displacement map derived from SVG filters to create a subtle distortion reminiscent of liquid glass. It’s primarily a visual illusion that does not rely on complex 3D rendering or true refraction physics. Instead, it uses a cleverly designed displacement map to manipulate the background context, resulting in a semi-realistic glass effect.
Limitations and Compatibility
It’s important to mention this approach isn’t universally supported. Currently, it does not work on iOS Safari or Firefox—browsers that lack full support for backdrop-filter or SVG filter features. Moreover, the displacement effect remains in 2D, so while it provides a convincing illusion, it does not incorporate advanced refraction or transparency models found in dedicated shader environments.
Why Is This Exciting?
A notable advantage of this method is its awareness of the environment behind the glass element. This means that dynamic content such as videos, selectable text, or interactive elements will still function normally, enhancing the practicality of the effect.
Design Inspiration
For those interested in the design process, I used this Figma design as a reference, which guided the visual style and concept.
Final Thoughts
While still experimental and limited in cross-browser support, this CSS-based liquid glass approximation exemplifies how creative CSS and SVG filters can push the boundaries of web design. It invites further experimentation, adaptation, and perhaps future enhancements to bring even more realistic glass effects directly to the browser.
