HTML and CSS are what you see in your browser. they're not just code, they're design tools. when you design with them, you're not on a flat canvas, you're crafting within the web's natural structure. think of the web as boxes inside boxes. this lets you freely move and compose content. with rnbw, you're designing inside the web's framework. working within these limits, you're embracing the essence of web design. rnbw is simple enough for anyone, flexible enough for anything, and open enough to use anyhow. it differs from traditional software by focusing on atomic concepts. while features are great "one-size-fits-all" solutions, atomic concepts multiply their meaning when combined. by breaking down complex ideas into atomic concepts, rnbw allows users to build their solutions in the best way possible that works for them, not others. we believe this design principle is the key to more powerful software.
