Curve CSS is a Blender add-on that enables the extraction, conversion, and reapplication of Float Curve data. It transforms curve profiles into normalized Float Curves using point simplification. Users can select any Float Curve node, such as those used in Geometry Nodes or shading setups, and copy the data directly to the clipboard formatted as CSS.

The tool natively supports generating either linear() functions or sampled values. Beyond exporting, Curve CSS allows users to reset Float Curves or paste previously saved curve data back into new or existing nodes. This enables consistent easing patterns and curve shapes to be transferred between different parts of a project or across entirely different Blender sessions.
