Is fontawesome totly work without data connection or data required???

Answer 1

All I know is you need to download the fonts,so they'll work offline...otherwise Nope!

Answer 2

It depends.

If you are using Font Awesome locally and download the necessary files to use the icons, you do not need an internet connection.

If you are using a Plaground or an online development environment, you do need the data connection. You also need data connection if you are only including the file from a CDN.

PS: If you include the file from a CDN, the browser may save it in the chache.
