The following tables compare XHTML compatibility and support for a number of layout engines. Please see the individual products' articles for further information. This article is not all-inclusive or necessarily up-to-date. Unless otherwise specified in footnotes, comparisons are based on the stable versions without any add-ons, extensions or external programs.
Only XHTML 1.1 is considered. XHTML 1.1 is necessarily XHTML 1.0 Strict with more elements and attributes deprecated. XHTML 2.0 was a working draft with no layout engine support, but work on it was abandoned[1] in 2009 in favor of work on HTML5 and XHTML5. XHTML 1.0 and HTML 4 (both served with text/html) are covered in comparison of layout engines (HTML). The comparison of XML capabilities are covered in comparison of layout engines (XML).
Version number, if possible, is provided for feature that is fully supported. Proprietary extensions are not included.

Values
Values indicate the level of support in the most recent version of the layout engine, or (if a version number is given) in the specified version. Version numbers without any other value indicate the version at which the layout engine first fully supported the feature.
| Value | Meaning |
|---|
| Yes | Indicates that the layout engine fully supports this property/element when valid values are used. |
| No | Indicates that the property/element is completely ignored. |
| Partial | Indicates that the property/element is understood, but that not all values are supported. Supported values are implemented correctly. |
| Incorrect | Indicates that the property/element is understood, but that it is not implemented correctly in all cases. |
| Experimental | Indicates that the property/element is understood, but supported under an alternate name. May be incomplete or buggy. |
| Dropped | Indicates that the property/element is no longer supported. |
| Nightly build | Indicates that the property/element is supported to some extent in an experimental/nightly build. Future support is expected. |
| Depends | Indicates that the property/element is supported only on certain platforms, or if certain settings are configured. |
Media types
The responses when a well-formatted XHTML document is served with different media types. Note that only application/xhtml+xml is the recommended media type.
KHTML media type notes
- application/xhtml+xml — KHTML supports this media type, but processes the document as HTML.
- application/xml, text/xml — HTML entities and custom entities defined by custom DTD are not recognized.
Combined profiles
Extending XHTML by combining with other applications of XML (not referring using img/object element).
