Contributing Author · Squoosh Next BlogCSS art uses combinations of box-shadow, border-radius, clip-path, and pseudo-elements to create visual compositions without any raster or vector image files. The technique was pioneered by artists like Diana Smith who created oil-painting-quality CSS portraits using thousands of layered box shadows. For practical application, CSS art enables loading logos and icons with zero image requests, perfect scalability at any resolution, and interactive states using transitions and transforms.
The clip-path polygon function can create arbitrary N-gon shapes. The conic-gradient function draws pie charts and color wheels. Multiple box-shadow values on a single element can create pixel grids for pixel art.
The primary limitation is maintainability: complex CSS art is difficult to edit, does not work with accessibility tools that expect img alt text, and cannot be generated programmatically without tooling.
