sections/article.html
Hi there!
You seem to be trying to write a Sphinx theme! Nice!
What you're seeing is the initial scaffolding provided by sphinx-basic-ng
which should serve as a decent base for most 3-column layouts.
If this is the first time you're seeing this, you probably want to be looking at the
Getting Started
page in the documentation.
Every "section" of this page is populated using a template. The name of the template
is visible in the sections. To override it, create your own template in the same
path in your templates directory. For example, creating a template named
sections/article.html
will override this section.
