There is something that puzzles me when writing CSS: combinators do not count when calculating the specificity.
Let's see the following code as an example:
At first glance,
section > div looks more specific than
section div as it targets a more precise set of elements (the
divs that are direct children of
section). So "Text 1" should be red, while "Text 2" should be blue.
...But when you run the code above, you see that that's not the case. All the text is blue. Even when
section > div is intuitively more specific than
section div, it is not more specific in CSS.
section > div and
section div then have the same specificity (0-0-2), and the last one in the code takes precedence.
While that decision makes sense from a practical point of view: if combinators were given a specificity weight –even something lower than a tag–, that change could unexpectedly affect the styling of millions of websites.
We could argue that it was not the right time to make such a change, but we could also argue that it won't be the right time ever. Even when, in my opinion, it is a change that should be done.
Because it makes sense from a semantic point of view: combinators add meaning and precision (therefore specificity) to a selector. From the example above,
section > div will always be a subset of
section div. It is more specific.
...Just not for CSS.
