Can't set string value for quotes property in skins
Description
Steps to reproduce
Log in
Hi, username! > My Dashboard > Skins > Create Site Skin (or a work skin, but the site skin option is right there, so let’s go with that)
Enter a title
Enter some CSS that uses the quotes property, e.g. q { quotes: '\00AB' '\00BB' }
Press Submit
What happens
You get the following error:
Sorry! We couldn't save this skin because:
The quotes property in q cannot have the value '\00AB' '\00BB', sorry!
There don't seem to be any rules for q
What should happen
You should be able to use the property as god and the W3C intended.
