What this tool does
Extract CSS Aspect Ratio Values scans pasted CSS as text, lists media sizing declarations with source lines, removes duplicate rows, and runs locally in your browser.
Common use cases
Extract CSS aspect-ratio, object-fit, and object-position declarations from pasted stylesheets, media-card CSS, component styles, framework output, or copied source before responsive media audits, card layout QA, migration, or documentation handoffs.
Use Extract CSS Aspect Ratio Values when you are working with copied API payloads, logs, encoded values, config snippets, identifiers, or debugging data and need a quick browser-local check before pasting the result into docs, tickets, tests, or another developer tool.
How to use it
- Paste CSS, style tags, component styles, image-card CSS, or copied source that contains aspect-ratio or object-fit declarations.
- Choose whether duplicate rows should be removed and whether output should be normalized for comparison.
- Review extracted rows with source lines, then copy the clean list for responsive media audits, card QA, migration notes, or documentation handoffs.
Example workflow
Copy a small payload or encoded value from an API response, request URL, log line, or config file. Run the focused check here, confirm the output is readable, then continue with related developer data tools such as validation, formatting, decoding, timestamp conversion, or CSV/JSON conversion.
