Explanation of the tables

Engine nomenclature

Rather than the names of web browsers, the names of the underlying engines are used. The browsers that use the various engines are listed below.

Layout engine Release version Preview version Used by

Amaya 11.3.1 11.3-pre Amaya

Gecko 6.0.2 8.0a2 All Mozilla software, including Firefox; SeaMonkey and Galeon; Camino; K-Meleon; Flock (up to 2.x); Epiphany-gecko; Debian IceWeasel; GNU IceCat (formerly GNU IceWeasel); Icedove, Iceape and Iceowl; Fennec

KHTML N/A Konqueror

Presto 2.9.168 2.9.168 Opera; Opera Mobile, Nintendo DS & DSi Browser‎; Internet Channel

Prince 7.1 N/A Prince XML

Tasman (IE 5.2.3 for Mac) none (aborted in 2003) Internet Explorer 5+ for Mac OS X

Trident 5.0 (IE 9) 6.0 (IE 10) Internet Explorer and other Internet Explorer shells like Maxthon (Microsoft Windows operating systems only), Windows Phone 7

WebKit 534.20 r83424 Safari (both desktop and mobile), Google Chrome, Maxthon 3, Shiira, iCab 4, OmniWeb 5.5+, Epiphany, Adobe AIR, Midori, Adobe Dreamweaver CS4 and CS5, Android browser, Palm webOS browser, Symbian S60 browser, OWB, Steam, Rekonq, Arora, Flock (version 3+), RockMelt

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.

Notes

^ Presto 2.0 had partial support for this property.

^ ^a ^b ^c Opera 9.5(Presto 2.1) support table claims support for this, but support tables for Presto 2.1.1 up to 2.5 indicate that this property is not supported.

^ Prior to version 2.4, Presto only had partial support for this property.

^ Incorrect in Gecko 1.8

^ Gecko had experimental support in version 1.9, with different names.^{[g 7]}
