About this tool
Everything CSS Viewer does happens on your own device. CSS Viewer processes CSS in your browser, applying the transformation to the styles you paste without altering their meaning.
Modern CSS syntax is preserved so your selectors and values come back intact. No data is sent anywhere, so it stays fast and private by default.
