As most of you already know, the Gantry 5 framework is one of the most advanced, most properly coded and most awesome frameworks available on the Web. It is the first-ever platform-independent framework and it works on Joomla, WordPress and the Grav CMS.
But developing a true platform-independent framework is quite of a challange. The Gantry 5 developers (the awesome guys at Rockettheme) had to come up with the concept and with the architecture and in my opinion they did it in the best possible way! They had to standardize the different aspects of the platforms which is why you see things like "Particles", "Atoms" and so on.
