As the screenshot I have added point out, the whole of the content uses a declarative and instructive verbiage while explaining concepts whereas a few of the headings in the Coding Style sections deviate from the rest in a way that they are more suggestive or in some cases not instructive but informative.

My suggestion would be to make it a little bit consistent with the rest of the headings while still keeping it's original suggestive meaning.
also I would love to work on the same as it seems like an easy fix.
