Use CSS Print Media Inventory when you need to inventory print media blocks and the declarations commonly used to shape printed output. The result is immediate and easy to verify before you reuse it.
Enter the values requested by CSS Print Media Inventory. The browser validates the input, performs the calculation locally and produces a copyable result with clear errors.
A practical use is to run CSS Print Media Inventory on a small sample first, confirm the output, and then process the complete value or list.
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
