Developed by guys at Automatic, Jetpack is a cool WordPress plugin that brings a lot features from WordPress.com to your self-hosted site on WordPress. I can name here a list of features that would make our life whole lot easier in managing our WordPress site, such as: Site statistics, Carousel for image galleries effect, Publicize, Mobile theme and so on. Seriously, lots of them are amazing and you should check them out.
In the scope this article, I will talk about one feature that we would highly recommend for our users to use, it is Custom CSS.
