Want to come up with a great design for a Facebook Page tab? The 960 grid system has become a standard among many we designers and developers and now one developer, Goran Mitic, has created the 520 grid system for Facebook Page designers and developers.
While I’m not sure how many people spend lots of time building designs for Facebook Pages, there is most definitely a small ecosystem built around the design and development of Pages. Goran built this tool specifically for the designers and developers who are part of that ecosystem. So next time you are building a Facebook Page for yourself or for a client, consider using the 520 grid system to help guide you as you come up with creative custom tabs, reveal tabs, etc.
