Deprecated Attributes for Hypertext Links
Earlier versions of HTML did not support CSS and the
link
,
visited
,
hover
, and
active
pseudo-classes. If a Web page author wanted to change the color of a hypertext
link, he or she would have to add the attributes
<body link=”
color
” vlink=”
color
” alink=”
color
”>
to the
<body>
tag, where the
link
attribute specifies the color of unvisited links, the
vlink
attribute specifies the color of visited links, and the
alink
attribute specifies the
color of active links. Colors had to be entered either as a supported color name or as a
hexadecimal color value. The
link
,
vlink
, and
alink
attributes have been deprecated
and their use is discouraged, but you still might see them in the code of older Web pages.
