Multiple classes

Are multiple classes supported? e.g.

```
/* input.css */
.class, 
[type="text"], 
[class*="lorem-1 lorem-2"],
[id^="myID"] { 
    color: red; 
}

```

```
/* Output example */
.class, 
[type="text"], 
[class*="test-lorem-1, test-lorem-2"],
[id^="test-myID"] { 
    color: red; 
}
```
