02 / YOUR PAGE

Repair your responsive layout.

Paste local HTML and optional CSS. Analyze actual layout at four browser widths, inspect a conservative patch, then download a sanitized layout copy.

This is a local HTML/CSS subset, not a full-site importer. Scripts and external resources are removed or blocked. The sanitized preview may differ from your original page. No URL import or network service is used by this tool.
