When creating a web app manifest for Chrome, you can specify display as fullscreen , standalone , minimal-ui or browser
display
fullscreen
standalone
minimal-ui
browser
What is the difference between fullscreen and standalone and when should I use this? They seem very similar to me.
When you use standalone , it looks like a native application. When you use fullscreen , there is no status bar, etc. Perhaps you want to use standalone , because fullscreen has a very specific use case (like games).
Acceptable display options: fullscreen , standalone , minimal-ui and browser in accordance with https://developer.mozilla.org/en-US/docs/Web/Manifest/display .
To display the Add to Home Screen command , you must set one of the following values: fullscreen , standalone or minimal-ui , see https://developers.google.com/web/fundamentals/app-install-banners/
The browser display browser is similar to leaving the field blank.
