Use Less to CSS

Compiles a self-contained stylesheet using the real Sass or Less compiler in a cancellable worker. Start with the sample, select the options and run the tool. Copy or download the result after reviewing it.

Behavior and limits

Compiles a self-contained stylesheet using the real Sass or Less compiler in a cancellable worker. External imports, modules, plugins, embedded JavaScript and file reads are disabled. Escaped identifiers and backticks are not accepted. URL references in generated CSS are not fetched. Output is CSS, not a reconstruction of the original abstractions.

Example input

@accent: #2563eb;
.card { color: @accent; &:hover { color: white; } }

Expected behavior for the example

.card uses #2563eb; a separate .card:hover rule uses white. The Less variable and nesting are compiled away.

Check important output in the application that will consume it. Use the tool directory to find related formats and tasks.
