Seemingly erroneous highlighting in Firefox

Our program outputs the image to the standard output stream (std::cout), so leave that alone and instead write to the error output stream (std::cerr):

Hang on. In Firefox, I get stb_image.h highlighted. But std::cerr and vec3 sometimes highlighted.

In the text, std:cerr is correctly styled with `` but isn't highlighted.

We have a CSS rule for .md code and another for .md p code. It looks like text inside a div.together may not be enclosed in a <p> element, so the styling rules are firing differently. One of the above specifies background, another does not.

Just need a general review of the CSS code styling and fix.
