                Use comments to create a table of contents and headers in your source code.
                This is useful for big files that need to be split up into sections.
                If the file is too big, however, it may be scoped too broadly, and should be
                broken down into multiple smaller files (#[i partials]).
                It&rsquo;s good practice to include the filenames at the top of each partial so that
                they outline the files when concatenated.

                Within partials or sub-files, keep sections and subsections only two levels deep.
                Keep in mind the #[i Inception rule]&mdash;#[strong three levels is too much].
                If you need that kind of
                complexity, it&rsquo;s better to split up the stylesheet into smaller files.
