A couple years late to the party, but I seem to have stumbled on a way that seems to allow a kind of nested comment...although, as an admitted NON expert, there may be issues.

It appears, if you just place an extra, undecorated set of braces around some css, the css inside, and even any uncommented text, is not recognized, at least by Chrome 58.0.3029.110 (64-bit):

Original (from an unrelated question and answer):

html, body, .container {
    height: 100%;
}
.container {
    display: -webkit-flexbox;
    display: -ms-flexbox;
    display: -webkit-flex;
    display: flex;
    -webkit-flex-align: center;
    -ms-flex-align: center;
    -webkit-align-items: center;
    align-items: center;
    justify-content: center;
}

Fiddle

With the brackets:

html, body, .container {
    height: 100%;
}

.container {
    display: -webkit-flexbox;
    display: -ms-flexbox;
    display: -webkit-flex;
    display: flex;
    -webkit-flex-align: center;
    -ms-flex-align: center;
    -webkit-align-items: center;
    align-items: center;
    justify-content: center;
}
/* ...act as comment? */ }

Kind of handy for dev work. The way I'm using this right now:
