HTML5 Deprecated Tags and Attributes


HTML5 is deprecating the following HTML4 elements (tags) and attributes. When HTML5 is released as a working standard you should stop using them altogether. Where possible we will list alternatives and W3 recommended suggestions for replacing these elements with something better.

Deprecated Tags:

<frame> - use <iframe> with CSS, or server side includes instead
<frameset> - use <iframe> with CSS, or server side includes instead
<noframes> -
<basefont> -
<big> -
<center> -
<font> -
<strike> -
<tt> -
<acronym> - use <abbr> instead
<applet> - use <embed> or <object> instead
<isindex>
<dir> - use <ul> instead
Deprecated Attributes:
rev and charset attributes on <link>, <a>
shape and coords attributes on <a>
longdesc attribute on <img>, <iframe>
target attribute on <link>
nohref attribute on <area>
profile attribute on <head>
version attribute on <html>
name attribute on <img> (use id instead)
scheme attribute on <meta>
archive, classid, codebase, codetype, declare and standby attributes on <object>
valuetype and type attributes on <param>
axis and abbr attributes on <td>, <th>
scope attribute on <td>
summary attribute on <table>
