Guideline 11. Use W3C technologies and guidelines.
Checkpoint 11.2 - Avoid deprecated features of W3C technologies
How do I do it?
The following tags have been removed from HTML 4.0 and therefore should not be used: <applet>, <basefont>, <center>, <dir>, <font>, <isindex>, <menu>, <s>, <strike> & <u> (http://www.codehelp.co.uk/html/deprecated.html).
Several attributes have also been deprecated including
- align (deprecated if used in <caption>, <iframe>, <img>, <input>, <object>, <legend>, <table>, <hr>, <div>, <h1..6>, <p>),
- alink (deprecated if used in <body>)
- background (deprecated if used in <body>)
- bgcolor (deprecated if used in <table>, <tr>, <td>, <th>,<body>)
- border (deprecated if used in <img>, <object>)
- clear (deprecated if used in <br>)
- compact (deprecated if used in <dl>, <ol>, <ul>)
- height (deprecated if used in <td>, <th>)
- hspace (deprecated if used in <img>,<object>)
- language (deprecated if used in <script>)
- link (deprecated if used in <body>)
- noshade (deprecated if used in <hr>)
- nowrap (deprecated if used in <td>, <th>)
- size (deprecated if used in <hr>)
- start (deprecated if used in <ol>)
- text (deprecated if used in <body>)
- type (deprecated if used in <li>, <ol>, <ul>
- value (deprecated if used in <li>)
- version (deprecated if used in <html>)
- vlink (deprecated if used in <body>)
- vspace (deprecated if used in <img>,<object>)
- width (deprecated if used in <hr>, <td>, <th>, <pre>)
How do I check that it meets the WCAG criteria?
Each page can be initially tested for <font> and <center> using the Edit > Find tool in Dreamweaver as these are the most common. If a page does not have either of these tags the other tags will be checked. The presence of any deprecated language features will result in the page failing the check.
