## Contextual Selectors

Tip: Often I see classes being used when a contextual selector would do!

`selector1 selector2 { ...rules... }`

Often you'll see this as ways to apply different rules in `header`, `main`, and `footer`

    main p {
    /* rules for p inside of main */
    }
    footer p {
    /* rules for p inside of main */
    }
    h2 {
    /* rules for h2 everywhere*/
    }
    section h2 {
    /* rules for h2 inside of section */
    }
    nav a:link,
    nav a:visited,
    nav a:hover,
    nav a:active {
      /* rules for nav links */
    }
    footer a:link,
    footer a:visited,
    footer a:hover,
    footer a:active {
      /* rules for nav links */
    }
