CSS Validation Plugin

I know there are a few validation tools out there that will link directly to the w3c css validator. However, I have a need where I will not have internet access.

My curiosity is this: Is there a plugin available that doesn’t require internet access that works in the same nature as the online w3c css validator? I have found something that works for HTML5, but not CSS.

They do have a “local” version you can download http://jigsaw.w3.org/css-validator/DOWNLOAD.html
