+### Deep components
+
 With BEM, you're allowed to have deep components where the DOM subtree can go down many levels deep. While this is true in RSCSS as well, the dependence on the child selector (`>`) makes this impractical.
 
 I view this more as a feature than a defect: it forces you to create new components for deep hierarchies, making this more manageable. RSCSS's use of `>` also makes it easy to visualize a DOM structure based on CSS styles, leading to self-documenting code.
