`If no input files are passed, it reads from stdin. If neither -o, --dir, or --replace is passed, it writes to stdout.

|
If there are multiple input files, the --dir or --replace option must be passed.
|
|
|
|
Input files may contain globs (e.g. src/**/*.css). If you pass an input directory, it will process all files in the directory and any subdirectories, respecting the glob pattern.
