Perfect start, as description says

Obviously you made this floating contact button for one of your own projects. You were nice enough to just publish it in case others needed it as-is. It’s painfully simple and easy to customize for people even vaguely familiar with web coding.

At the time of this review it doesn’t have any bells or whistles for customization, but the description says it plainly. You saved me a little bit of my own time by sharing what you made. All I adjusted for myself was my icon, position, and size. Thanks!
