KHTML is faster than the Gecko layout engine, its main open source rival and core of the Mozilla and Mozilla Firefox browsers, among others. However, being a less widely known browser, many websites fail to support it or claim no support even if the site does work.

KHTML and Apple

The engine was adopted by Apple in 2002 for its Safari web browser. Apple publishes the source code for up to date and all previous versions of their version of the KHTML engine, called WebCore and WebKit, as required by the LGPL. The exchange of code patches between the two branches of KHTML has diverged because the projects have increasingly different approaches. [1] Apple Computer, Inc. ... For album titles with the same name, see 2002 (album). ... Safari is a web browser developed by Apple Computer, Inc. ... WebCore is a framework developed by Apple, and licensed under the LGPL, to provide an HTML layout engine for Mac OS X. It is one of the two primary components of the WebKit framework (the other being JavaScriptCore). ... WebKit is an application framework included with Mac OS X v10. ... GNU logo The GNU Lesser General Public License (formerly the GNU Library General Public License) is a free software license published by the Free Software Foundation. ...

Contributing to the seperation, Apple had not complied with parts of the Open Source philosophy. Examples include Apple working on their version of KHTML for a year before making their fork public, and Apple sometimes submitting their changes in large patches that incorporate a great number of changes, in some cases leaving code to do with future feature additions undocumented. The former example made it difficult for the KDE developers to incorporate the changes. Regardless, the KDE project has managed to incorporate a number of changes by Apple that have added features and improved KHTML's rendering speed, an example being the addition of Acid2 compliance. Open source refers to projects that are open to the public and which draw on other projects that are freely available to the general public. ... The optimal result for Acid2. ...

Apple cites that some changes involved Mac OS X-specific features (e.g. Objective-C, KWQ, OS X calls) which are absent in KHTML/Linux, which called for different development tactics. [2] Mac OS X (official IPA pronunciation: ) is a line of proprietary, graphical operating systems developed, marketed, and sold by Apple Computer, the latest of which is pre-loaded on all currently shipping Macintosh computers. ... Objective-C, often referred to as ObjC or more seldomly as Objective C or Obj-C, is an object oriented programming language implemented as an extension to C. It is used primarily on Mac OS X and GNUstep, two environments based on the OpenStep standard, and is the primary language... KWQ is Apples port of Qt that allows its version of the KHTML rendering engine to function in Mac OS X. KWQ and KHTML together make up the OS X WebCore framework. ... Linux (also known as GNU/Linux) is a Unix-like computer operating system. ...

Apple has since released changes of the sourcecode of its KHTML fork in a CVS repository. [3] CVS can refer to: Antisubmarine aircraft carriers (CVS), United States Navys hull classification symbol. ...
