CSS can achieve visual effects similar to WebGL through layering and blend modes, allowing high-quality shaders without JavaScript. Using properties like mix-blend-mode, gradients, and nested divs, developers can simulate lighting effects and create dynamic images. Techniques include specularity with gradient manipulation, blending with masks for realistic lighting, and exploring color blends for effects like auroras and holograms. While powerful, CSS blend modes can impact performance, especially with complex layers, suggesting caution in their use for web projects.
