I'm working with the new Rolltemplate feature on Dev and I need some CSS assistance. I am trying via CSS to add a '+' symbol in front of any inline roll result that is not a negative number. I can do this to add the '+' symbol before any inline roll result:  .sheet-rolltemplate-test .inlinerollresult::before {    content:"+";  }  Is there an attribute I can use the  [ attribute = value ]  selector on to test for either the '-' sign or a positive number?
