CSS Lint should do validation

[thierryk]

was: wrong shorthand font syntax should return an error

Rules like these:

.selector {
    font: 2em;
}
.selector {
    font: bold 2em;
}

Should return an error as the shorthand syntax requires at least to declare a font-size and a font-family.
The above may work in IE6 quirks, but should fail in modern browsers.

I think this falls under a more general category of "CSS Lint should do CSS validation." Definitely on the roadmap.

First bits of this are done. Need to move onto the new, more complicated properties.

I somewhat question the necessity of this given the existence of https://github.com/twolfson/css-validator
