ABOUT
One small tool for a specific CSS question.
“At this point in time, how far has this easing function progressed?”
Bezierframe answers that question for one cubic Bézier timing function. You can use a standard preset or enter controls, inspect the result at one time percentage and keep a local text or CSV record. The table samples the same curve; it is not a separate calculator.
The tool is free and does not require an account. Its source has no active advertising, analytics or consent-platform loaders. Advertising may support it later, subject to the host’s actual setup and appropriate consent. Free access does not depend on an advertising decision.
Calculation uses exact parsing of accepted decimal inputs and a bracketed numerical inverse. Worked examples and limits are available so you can judge whether the model fits your task. It is not a live browser rendering test or animation accessibility assessment.
