Wikipedia:WikiProject Usability/HTML

This Wikipedia page may require cleanup to meet Wikipedia's quality standards. No cleanup reason has been specified. Please help improve this Wikipedia page if you can; the talk page may contain suggestions.

Wiki supports a subset of XHTML, e.g. <br /> instead of <br>.

Wikipedia allows the use of HTML directly, and the use of CSS through the style="[…]" and class="[…]" attributes.

We believe that:

• The use of HTML instead of Wiki markup is discouraged
• If HTML and CSS must be used, editors should know how to use them properly, with regard to:
  • W3C standards
  • Cross-browser compatibility
