SiteOrigin CSS


This is one of the best CSS plugins out there. It's WAY better for custom CSS than the built in WP way. 



While writing this review, I made two feature requests which would bump it up to five stars. 



One thing I'm personally missing is a sort of CSS guide. As in, links to the W3C page of that properity for people to read up upon.


Amazing stuff

Powerful, simple CSS editing for WordPress. Visual controls & real-time previews for effortless site customization.
