The local-linkpseudo-class for CSS allows authors to style hyperlinks based on the users current location within a site.
It represents an element that is the source anchor of a hyperlink whose target's absolute URL matches the element's own document URL. If the hyperlink's target includes a fragment URL, then the fragment URL of the current URL must also match; if it does not, then the fragment URL portion of the current URL is not taken into account in the comparison.
