Synopsis
<a> . . . </a>
Defines an
anchor
that can be used as a hypertext link or a named fragment within the doc-
ument. When the
href
attribute is set to a valid URI, the anchor is a hypertext link to a web
page, page fragment, or another resource. The
id
attribute labels an anchor and allows it to
serve as the destination point of a link. An
a
element may have both
href
and
id
attributes.
The
href
attribute may be omitted to use an
a
element as a “placeholder link.”
HTML5 permits flow content (block elements) within
a
elements. There must be no inter-
active content (
