Unable to preview HTML in VSCode Live html preview

If you are using an extension called Live HTML Previewer, there is a bug that says that as of June 2020, this extension cannot be previewed.This is because The features that Live HTML Previewer used with the VSCode upgrade are no longer available.

Instead, search for other extensions and try using them.For example, there is an extension called HTML Preview.

As stated here, the preview function is not included.There are extensions available in VS Code Marketplace.Open the Extensions view (⇧ XX) and search in Live Preview or html Preview to see a list of available HTML preview extensions.
Instead of adding extensions, you can tap the html file you are creating and check it with chromium.

If it's angular, this is helpful!
Sorry for the English.br/> https://medium.com/ @MarkPieszak/debugging-angular-cli-inside-vscode-with-browser/brew/brew/8> Basically, installing browser preview and debugger for chrome is enough, but if it's angular, json file settings are required.
