LESS.css Nested Rules - is this valid LESS?
===

I wanted to make it easier to manage my font rules in LESS, so i created the following rule based on the Nested Rules section in the official LESS guide.

However, they only provide example for nested rules that contain additional classes, so i wanted to know if writing it this way is valid or not, and if not, is there a way i can make my code succinct and take advantage of nested rules?

I'd like to be able to use the nested rule feature to specify parameters for h1 and h3 for the .logo class.

    .logo {
    h1 {.font-setup ("Euphemia UCAS", 200px, normal, #222);}
    h3 {.font-setup ("Euphemia UCAS", 40px, normal, #222);}
			
            text-shadow: 0px 2px 3px #555;
			}
