The hostnet/atom-css-sniffer package is a companion package to the hostnet/css-sniffer package. It provides the CSS and LESS sniffing in your Atom IDE while you type. It will show any errors in your code.

Installation

1. Install the linter package (with the dependencies) by steelbrain.
2. Install the atom-css-sniffer.

And you are done.

Getting started

Make sure you have a project that has the hostnet/css-sniffer as a composer dependency and it is installed. If you have that, opening a CSS or a LESS file should trigger the sniffer an will notify you of any errors.

Everything else is taken care of.
