Combining Selectors
Selectors can be combined into comma-separated groups so that a single declaration can be applied to multiple selectors.
Is this:
h1, h2, h3, h4, h5, h6 { color: maroon;}
Better than this?:
h1 { color: maroon; }
h2 { color: maroon; }
h3 { color: maroon; }
h4 { color: maroon; }
h5 { color: maroon; }
h6 { color: maroon; }
