It is a different style of programming. It is mentioned every once in
a while, but there isn't anything concrete being designed. (And I
don't think there should be, either.)

To avoid repeating rules, CSS provides grouping of selectors and
@import. Both of them, I think, are more direct than defining
templates. Indirection is often powerful, but still I'd like to avoid
it as long as possible.

I would use grouping instead:

    /* Set the common style */
    table, p.special, div.other, blockquote.foo {
        border: 2px solid red;
        height: 100%
    }
    ...

    /* Override the common style for individual elements */
    table {
        border-color: blue
    }
