Copied your code and inserted into workspaces and it worked. Not sure why it's not showing on your end.

Try cutting it and pasting it. Sometimes workspaces can act a little funny.

When running a simple http server, sometimes the previous code gets cached, so you don't see your latest changes. Try a hard reload (shift command r on mac) or two finger click (mac) (right click? on PC?) on the refresh button on the browser (choose 'hard reload')

You would need to make sure the browser isn't loading cached files.

To this using http-server, you would need to set it to a port you haven't used before and use the -c-1 command

Example:

http-server -c-1 -p 4000
