The cave exposes a single function that takes the file path to a stylesheet and a string containing valid CSS you want to remove from the provided stylesheet.
cave(stylesheet, options, done)The options object contains the following properties.
| Property | Description |
|---|---|
css | The CSS rules to remove from the stylesheet. e.g: a { color: #f00; } |
Cave will produce an AST and remove any matching rules, then the done callback will be executed.
Cave works well with standard input.
cat path/to/file | cave <stylesheet> > slim.css
You can also pass in the critical CSS file as an option.
