HTML 11 shows a preview of static and dynamic web pages you are currently editing in Visual Studio, on desktop and mobile devices. The preview for static .html pages is updated as you type. The preview for dynamic .cshtml, .vbhtml, .aspx and .razor pages is updated when you save a document. You can position preview tool windows alongside the HTML editor or outside the main Visual Studio window, e.g. on a second monitor. HTML is rendered using Chromium Embedded Framework v92. The mobile device preview is simulated with Chromium DevTools Device Mode and you can open a page on a running Android emulator.
