Limits and behavior
CSS syntax parsing is not a compatibility or rendering validator. Vendor-specific constructs follow css-tree parsing support. Maximum total input 1 MB, output 3 MB, JSON nesting 64 levels. Processing stays in your browser worker. Input is limited to 1 MB and output to 3 MB. No input content is saved by CraftAI.
Beautify CSS source code
Reformat supported CSS rules to improve readability when editing styles and debugging selectors.
Does CSS formatting change computed browser styles?
It is intended to preserve parsed CSS behavior; always check complex stylesheets and vendor-specific syntax.
