use call triggers, variants?

[crcn]

public variant mobile trigger {
  "@media screen and (max-width: 100px)"
}

public component Test {
  render div {
    style trigger mobile {
    
    }
  }
}

Alternatively:

public variant mobile when "@media screen and (max-width: 100px)"

public component Test {
  render div {
    style when mobile {
    
    }
  }
}

Need to consider +
