...and if not, why not? :)
PHP and JS have this simple, intuitive, useful feature: You can place two slashes (//) to comment out everything from the slashes to the end of the line, without having to actually go to the line's end and place something that terminates the comment.
CSS hasn't had anything like this in my experience, but I'm wondering if maybe there's been some development there yet. And if not, does anyone know of a hack, a workaround, or a practice of some sort, that might mimic such a feature?
