EdgeHTMLs

EdgeHTML was the proprietary HTML rendering engine developed by Microsoft for its Edge browser. It was introduced with the first version of Microsoft Edge in 2015, replacing the aging Trident engine used in Internet Explorer. EdgeHTML was designed to be more modern, performant, and standards-compliant than its predecessor. It aimed to improve page load times, reduce memory usage, and offer better support for emerging web technologies.

Key features of EdgeHTML included improved JavaScript performance through its Chakra engine, enhanced support for CSS3 and HTML5 features, and a focus on web standards. Microsoft actively worked to align EdgeHTML with web standards to ensure better compatibility with websites across different browsers. However, despite its advancements, EdgeHTML faced criticism for its slower adoption of new web standards compared to engines like Blink (used in Chrome) and Gecko (used in Firefox).

In 2018, Microsoft announced a significant shift for its Edge browser. They decided to re-engineer Edge using the Chromium open-source project, which also powers Google Chrome and many other browsers. This transition meant replacing EdgeHTML with the Blink rendering engine. The new Chromium-based Edge browser was released in January 2020, marking the end of EdgeHTML's development and usage. While EdgeHTML is no longer actively developed or used in Microsoft's primary browser, it represented a chapter in Microsoft's web browser evolution.
