Checkpoint 1.4 - Core

Deprecated elements are not used

WCAG 1.0 Priority 2

WCAG Guideline 11. Use W3C technologies and guidelines.

Avoid deprecated features of W3C technologies. A deprecated element or attribute is one that has been outdated by newer constructs. Deprecated elements may become obsolete in future versions of HTML.

Requirement

Do not use any deprecated HTML 4.01 elements or attributes. These should be replaced by some other mechanism such as stylesheets or other HTML element and attributes.

Recommendation

Refer to the listing of deprecated elements and attributes. Each deprecated element or attribute has suggested techniques to help in avoiding their use.

Note: the deprecated tag of <u> should never be used in a web page as it makes users think the underlined wording is a hyperlink.

Checking Tool

  • Internet Explorer - AIS toolbar: Source > Deprecated HTML > Deprecated Elements and Attributes
  • Firefox - Web Developer's Toolbar: Outline > Outline Deprecated Elements
