The simple answer is that you cannot (change the user flashing carriage) with javascript, html or css as it is created and managed by chrome (browser outside of the DOM).

The code examples shown are pretty old, but the idea remains the same - make a flashing box and make it enter an input ...
With all that said, I highly recommend not using it for anything other than the smallest niche, βfor fun,β since I have a javascript function and you change the DOM on every keyDown that borders on user imho abuse.
