0 / 30,000 characters. No upload, storage, or account required.
CSS max extraction workflows
Use this extractor when pasted styles need a browser-local inventory of responsive minimum choices before refactoring or documenting sizing rules.
Audit responsive floors
Pair this with Extract CSS Min Functions, Extract CSS Clamp Functions, and Extract CSS Calc Functions.
Review spacing and type
Use Extract CSS Box Model Values, Extract CSS Font Sizes, and Extract CSS Var References together.
Clean copied output
Send extracted rows to Remove Duplicate Lines, Sort Lines, or Normalize Whitespace.
What this tool does
Extract CSS Max Functions scans pasted CSS as text, lists max(...) expressions with source lines, removes duplicate rows, and runs locally in your browser.
Common use cases
Extract CSS max(...) expressions from pasted stylesheets, component CSS, design-token files, framework output, or copied source before responsive floor audits, spacing review, migration, QA, or documentation handoffs.
Use Extract CSS Max Functions 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 stylesheets, component CSS, framework output, design-token files, or copied style blocks.
- Choose whether duplicate rows should be removed and whether output should be normalized for comparison.
- Review extracted max(...) rows with source lines, then copy the clean list for responsive layout, migration, QA, or documentation audits.
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.
Privacy note
Extract CSS Max Functions runs locally in your browser. Your pasted CSS is not uploaded, rendered, fetched, crawled, executed, stored, or logged.
