Trident[1][2][3] (also known as MSHTML[1][2][5]) is a proprietary browser engine for the Microsoft Windows version of Internet Explorer, developed by Microsoft.

MSHTML debuted with the release of Internet Explorer 4 in 1997. For versions 7 and 8 of Internet Explorer, Microsoft made significant changes to MSHTML's layout capabilities to improve compliance with Web standards and add support for new technologies.[6][7][8]

MSHTML will continue to receive security updates[9] for the IE mode of Microsoft Edge until at least 2029. However, support for new Web standards will not be added.
