About this Experiment

An investigation into the outer limits of CSS visual capabilities — creating atmospheric fog, depth of field, and light scattering effects using only CSS filters and blend modes.

Technical Approach

By layering multiple pseudo-elements with carefully tuned filter values and blend modes, we can achieve effects that are typically reserved for WebGL shaders, entirely within the CSS specification.
