[jogibear9988]

Expected Behaviour

template areas should be stringified like this:

grid-template-areas: "menu head head head"
                     "menu main main main"
                     "menu main main main"
                     "menu footer footer footer";

Actual Behaviour

grid-template-areas: "menu head head head"
"menu main main main"
"menu main main main"
"menu footer footer footer";
