Do you have any good reason why authors waive this convenience? Don't
just consider plain text style sheets, consider CSS DOM manipulations.
You would have to hardcode what elements and properties should be
changed if you want to change some color and thus the script would get
large and it won't be easy to port the script to other documents, unless
you give all those elements some ID. Consider SVG documents that want to
animate some colors automatically or on user action, maybe to make some
graphic more accessible for color blind people with just one click. SVG
come with mechanims to reuse shapes, paths, gradients and so on, why
shouldn't CSS have some mechanism to reuse colors?
