+    How many levels of nesting do you have in your code? It's something I try to keep to a minimum.
+---
+One of my goals when coding is to reduce the amount of nesting in the code I write.
+
+I mean both in my PHP code where if conditions and foreach loops can be nested within each other, and CSS and Sass files, which support nesting CSS rules.
+
+My aim is to have a maximum of two or three levels of indentation, though sometimes this isn't possible.
+
+Doing so where I can, though, makes my code easier to read and understand and encourages other clean code approaches, such as having small and well-named functions.
+
+In CSS or Sass, avoiding nesting makes it easier to find a rule I'm looking for instead of having to find how rules have been nested or names have been concatenated - making it hard to search or grep for a string.
+
+This approach is part of "object callisthenics", which was introduced by Jeff Bay and includes other approaches that I like to follow, such as not using the `else` keyword and other good practices that I like to try and implement when possible.--
