// Links
//
// Hyperlinks are used to allow the user to navigate to other resources or to
// download a resource.
//
// The order of link states are based on Eric Meyer's article:
// http://meyerweb.com/eric/thoughts/2007/06/11/who-ordered-the-link-states
//
// :visited - A link that has already been visited.
// :hover   - A link that is being hovered over.
// :focus   - A link that has been given keyboard focus.
// :active  - A link that is being actively clicked.

// Any element can receive focus, but only links can be visited, so we can
// safely lower this selector's specificity. This also ensures visited links
// with additional styles won't have their styles overridden.
