CSS Type Scale
Generate a consistent font-size scale from a base size and ratio, with reusable CSS variables.
It is only processed in the browser, not uploading or saving. Leaving the page will be cleared; the calculation can also be cleared and the result can be discarded. Do not enter other people's credentials or private keys.
