Editing KHTML (section)

===Re-write and improvement===
The real work on KHTML actually started between May and October 1999, with the realization that the choice facing the project was "either do a significant effort to move KHTML forward or to use [[Mozilla]]"<ref name="auto"/> and with adding support for [[JavaScript]] as the highest priority. So in May 1999, Lars Knoll<ref>{{cite web |url=https://behindkde.org/node/145/ |title=Lars Knoll &#124; Behind KDE |website=Behindkde.org |access-date=1 September 2019}}</ref> began doing research with an eye toward implementing the [[Document Object Model|DOM]] specification, finally announcing<ref>{{cite web |url=https://marc.info/?l=kfm-devel&m=93489518402924 |title='changes in KHTML' - MARC |website=Marc.info |access-date=1 September 2019}}</ref> on August 16, 1999 that he had checked in<ref>{{cite web |url=https://marc.info/?l=kde-commits&m=93476738632582 |title='khtml_to_dom: kdelibs/khtml' - MARC |website=Marc.info |access-date=1 September 2019}}</ref> what amounted to a complete rewrite of the KHTML library—changing KHTML to use the standard [[Document Object Model|DOM]] as its internal document representation. That in turn allowed the beginnings of [[JavaScript]] support to be added in October 1999,<ref name="auto"/> followed shortly afterwards with the integration of [[KJS (JavaScript engine)|KJS]] by [[Harri Porten]].

In the closing months of 1999 and first few months of 2000, Knoll did further work with Antti Koivisto and Dirk Mueller<ref name="auto"/><ref>{{cite web |url=http://trac.webkit.org/projects/webkit/wiki/WebKit%20Team#AnttiKoivistoanttikreview |title=WebKit Team – WebKit |website=Trac.webkit.org |access-date=1 September 2019}}</ref><ref>{{cite web |url=https://behindkde.org/node/211/ |title=Dirk Mueller &#124; Behind KDE |website=Behindkde.org |access-date=1 September 2019}}</ref> to add CSS support and to refine and stabilize the KHTML architecture,<ref name="auto"/> with most of that work being completed by March 2000. Among other things, those changes enabled KHTML to become the second browser after [[Internet Explorer]] to correctly support [[Hebrew]] and [[Arabic]] and languages written [[Bi-directional text|right-to-left]]<ref name="auto"/>—before [[Mozilla]] had such support.

[[KDE 2.0]] was the first KDE release (on October 23, 2000) to include KHTML<ref>{{cite web |url=https://www.youtube.com/watch?v=Tldf1rT0Rn0 |title=Lars Knoll and George Staikos: From KDE to WebKit |date=26 August 2011 |publisher=[[YouTube]] |access-date=1 September 2019}}</ref> (as the rendering engine of the new [[Konqueror]] [[file manager|file]] and [[web browser]], which replaced the monolithic KDE File Manager).
