[csswg-drafts] CSS Regex Selector

programmer5000-com has just created a new issue for 
https://github.com/w3c/csswg-drafts:

== CSS Regex Selector ==
This would resolve #1008.
It would be very nice to have the ability to do a regex selector on a 
tag, like this:
```CSS
/**Match all h1-h6 tags**/
/^h\d$/i{
     font-family: "Roboto", sans-serif;
}
/**Match all ruby elements**/
/^r[a-z]+/i{
     font-weight: bold;
}
```
and so on. Better yet, allow regex to be used in classes, etc.
```CSS
/**Match sections with ids of card-1, card-2, etc.**/
section#/card-\d+/i{
     padding: 10px;
     border-radius: 10px;
     background: white;
}
```
This would be an extremely helpful feature of CSS that would help 
developers write lean, beautiful code and I would love to see it added
 to the spec!
