HTML 11 extension provides a tool window in Visual Studio 2017/2019 showing preview of an HTML document you are currently editing:
The preview is updated as you type. When you change a .css or a .js file referenced in the HTML document, the preview is updated after you save the referenced file.
To initially open the HTML 11 tool window, select View - Other Windows - HTML 11:
You can position the opened tool window alongside the HTML editor or outside the main Visual Studio window, e.g. on a second monitor.
HTML is rendered using Chromium Embedded Framework v75. You can open the Developer tools window with the HTML11.ShowDevTools command.
