40 CSS Reference Websites and Resources

If you want to design websites or modify your existing website design, then you need to have at least a basic knowledge of Cascading Style Sheets (CSS). Thankfully, CSS is a very easy language to get to a grip on, however you may find it takes a little more time to master it. Today we would like to share with you 40 resources that will help you on your CSS journey. We have listed great CSS references and CSS blogs for learning more about the language; not to mention compatibility tables to help you remember how certain browsers handle certain CSS elements. We have also included services that help you generate code and cheat sheets for easy reference of selectors, properties and pseudo-classes. So let's get to it, shall we?
