Editing WorldWideWeb (section)

==Features==
Since WorldWideWeb was developed on and for the [[NeXTSTEP]] platform, the program uses many of NeXTSTEP's components – WorldWideWeb's [[Browser engine|layout engine]] was built around NeXTSTEP's Text [[class (computer science)|class]].<ref name="faq-www"/>

WorldWideWeb is capable of displaying basic [[style sheet (web development)|style sheets]],<ref name="faq"/> downloading and opening any file type with a MIME type that is also supported by the NeXT system ([[PostScript]],<ref name="IEEE">{{cite web|url=http://www.computer.org/portal/web/computingnow/ic-cailliau|title=Interview Robert Cailliau on the WWW Proposal: "How It Really Happened."|last1=Petrie|first1=Charles|last2=Cailliau|first2=Robert|author-link2=Robert Cailliau|date=November 1997|publisher=[[Institute of Electrical and Electronics Engineers]]|url-status=live|archive-url=https://web.archive.org/web/20110106041256/http://www.computer.org/portal/web/computingnow/ic-cailliau|archive-date=6 January 2011|access-date=18 August 2010}}</ref><ref name="faq"/> movies, and sounds<ref name="faq"/>), browsing [[newsgroup]]s, and [[spell checker|spellchecking]]. In earlier versions, images are displayed in separate windows, until NeXTSTEP's Text class gained support for Image objects.<ref name="faq"/> WorldWideWeb is able to use different protocols: [[File Transfer Protocol|FTP]], [[Hypertext Transfer Protocol|HTTP]], [[Network News Transfer Protocol|NNTP]], and [[file URI scheme|local files]]. Later versions are able to display inline images.<ref name="faq-www"/>

The browser is also a [[WYSIWYG]] editor.<ref name="faq-www"/><ref name="IEEE"/> It allows the simultaneous editing and linking of many pages in different windows. The functions "Mark Selection", which creates an anchor, and "Link to Marked", which makes the selected text an anchor linking to the last marked anchor, allow the creation of links. Editing pages remotely is not possible, as the [[Hypertext Transfer Protocol#Request methods|HTTP PUT]] [[method (computer science)|method]] had not yet been implemented during the period of the application's active development.<ref name="faq-www"/> Files can be edited in a local file system which is in turn served onto the Web by an HTTP server.{{cn|date=December 2020}}

WorldWideWeb's navigation panel contains Next and Previous buttons that automatically navigate to the next or previous link on the last page visited, similar to [[Opera (web browser)|Opera]]'s Rewind and Fast Forward buttons, or [[HyperCard]]; i.e., if one navigated to a page from a table of links, the Previous button would cause the browser to load the previous page linked in the table.<ref name="faq-www"/> This is useful for web pages which contain lists of links. Many still do, but the user interface link-chaining was not adopted by other contemporary browser writers, and it only gained popularity later. An equivalent functionality is nowadays provided by connecting web pages with explicit navigation buttons repeated on each webpage among those links, or with [[typed link]]s in the headers of the page. This places more of a burden on web site designers and developers, but allows them to control the presentation of the navigation links.{{cn|date=December 2020}}

WorldWideWeb does not have [[Bookmark (World Wide Web)|bookmarks]] as they exist in later browsers, but a similar feature was provided: to save a link for later use, users could link to it from their own home page (start page). Users could create multiple home pages, similar to folders in modern web browsers' bookmarks.<ref name="IEEE"/>
