Over the next few blog posts we will be looking at how we can restyle an entire document without changing its contents. This is one of the key strengths of LaTeX: separating content from style. There are, of course, several aspects of a document that can be interesting to restyle, but we will focus on some of the primary elements: the table of contents, chapter headings, part, section, subsection, etc. headings, and finally the page headers and footers. As usual, we will do this by investigating the memoir document class.
