Colour coding CSS

In general, everything before the colon is green; after the colon I get either green or orange. Does the different color suggest an error?

Another thread: Probably better! But in a nutshell: So far you are lucky! There exist at least another color: Indigo for Errors and Warnings (from my examples).

Error: position is a (correct) property, but the value ? doesn't exist.

Warning: -epub-ruby-position: over: -epub-ruby-position is an unknown property name (as the warning says).
over is a non-existent value. This is not explicitly named as a unknown property can have no value of course, either existing or not.

Demonstration!
Warning: -epub-ruby-position: left: left is an existing value, but the warning is the same than with non-existent value over.

The person who asked that question received a satisfactory answer (the colors indicate different types, as in any other editor possessed of syntax highlighting) over two months ago.

@eschwartz
My post can be understood as a complementary approach and practice-based. The period gone is irrelevant as long as the post as such is okay.

Your link points more toward the general use of colors for 'Syntax highlighting' rather than the specific one in calibre.

[eschwartz]

By design -- you seem to be implying the colors have nothing to do with syntax and indicate errors instead, which is flat out wrong.
Either way, the time lapse is indeed relevant, since necroposting is an official no-no.

@eschwartz As far as I have understood now: Defined/undefined HTML elements, attributes, properties or values (or whatsoever) gets syntax highlightning in calibre. But a undefined ''xyz'' must not be wrong automatically and therefore to be removed.

Anyway, we shouldn't deepen this issue further. Currently I understand these matters very little. By the time I'm going to gain more insight so tolerance of the opponent is welcome.
