.dcss-solve

Finds the input at which your formula reaches a target, by halving the range, as a spreadsheet’s Goal Seek does.

CSS
.sq i { --dcss-formula: calc(100 * pow(var(--dcss-input), 2)); }

Notes

Each call takes your own formula, written once as --dcss-formula in terms of --dcss-input. A .dcss-solve with data-dcss-steps="n" halves the range n times, one nested element a step, and BASICSS writes those elements for you: npx basicss page.html -o built.html.
