My Web-related notes

    - Browser allowance for cross-origin inclusion of style sheet.
        : see https://en.wikipedia.org/wiki/Cross-origin_resource_sharing : ‘A web page may freely embed
          cross-origin images, stylesheets, scripts, iframes, and videos.’
        - A style sheet is considered an *embedded resource*.
            : re `embedded resource` see @ non-fractal

    - Hypertext Transfer Protocol (HTTP) status codes.

        - The markdown form of project files `README.html`.
        - There the HTML is Markdown compatible only for sake of the Git Hub adaptor link (`README.md`)
          which is a sibling and effective alias of each `README.html`.
