Frequently Asked Questions

Variables and mixins?

@variables inline to values, mixins expand at call sites — output is dependency-free CSS. Guarded mixins resolve per call.

Nesting preserved?

Nested rules flatten to full selectors correctly. Deep nesting expands verbosely — refactor output for production.

Why migrate off LESS?

Native CSS now covers variables and nesting; dropping the preprocessor removes build steps. Convert once, delete the dependency.

Is stylesheet data uploaded?

No — compilation runs locally in your browser. Code never leaves your device.
