HTML Reference (Webmaster in a Nutshell, 3rd Edition)

3.1. Core Attributes

Prior to HTML Version 4, there were few attributes that could be used consistently for all HTML tags. HTML 4 changes this, defining a set of 16 core attributes that can be applied to almost all the tags in the language. For brevity, we list these core attributes in this section and spare you the redundancies in the table that follows:

class=name

A small handful of tags do not accept all of these attributes. They are:

<applet>      <embed>      <html>      <marquee>      <script>
<base>        <font>       <iframe>     <meta>        <server>
<basefont>    <frame>      <ilayer>     <multicol>    <spacer>
<bdo>         <frameset>   <isindex>    <nobr>        <style>
<br>          <head>       <keygen>     <noembed>     <title>   
<comment>     <hr>         <layer>      <param>       <wbr>

In the reference section, we list all the attributes supported by these special tags, including the common ones. For all other tags, assume the common attributes in the preceding list apply.
