The existing Netscape rendering engine, originally written for <a href="/wiki/Netscape_Navigator" title="Netscape Navigator">Netscape Navigator</a> 1.0 and upgraded through the years, was slow, did not comply well with W3C standards, had limited support for <a href="/wiki/Dynamic_HTML" title="Dynamic HTML">dynamic HTML</a> and lacked features such as incremental reflow (when the layout engine rearranges elements on the screen as new data is downloaded and added to the page). The new layout engine was developed in parallel with the old, with the intention being to integrate it into Netscape Communicator when it was mature and stable. At least one more major revision of Netscape was expected to be released with the old layout engine before the switch. </p><p>After the launch of the Mozilla project in early 1998, the new layout engine code was released under an open-source license. Originally unveiled as <i>Raptor</i>, the name had to be changed to <i>NGLayout</i> (next generation layout) due to <a href="/wiki/Trademark" title="Trademark">trademark</a> problems. Netscape later rebranded NGLayout as <i>Gecko</i>. While <a href="/wiki/Mozilla_Organization" class="mw-redirect" title="Mozilla Organization">Mozilla Organization</a> (the forerunner of the <a href="/wiki/Mozilla_Foundation" title="Mozilla Foundation">Mozilla Foundation</a>) initially continued to use the NGLayout name (Gecko was a Netscape trademark),<sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup> eventually the Gecko branding won out.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

While this decision was popular with web standards advocates, it was largely unpopular with Netscape developers, who were unhappy with the six months given for the rewrite.<sup id="cite_ref-Collins_interview_11-0" class="reference"><a href="#cite_note-Collins_interview-11"><span class="cite-bracket">[</span>11<span class="cite-bracket">]</span></a></sup> It also meant that most of the work done for <a href="/wiki/Netscape_5" class="mw-redirect" title="Netscape 5">Netscape Communicator 5.0</a> (including development on the <a href="/wiki/Mariner_(layout_engine)" class="mw-redirect" title="Mariner (layout engine)">Mariner</a> improvements to the old layout engine) had to be abandoned.
