How do I set the icon like this (in the title) that appears on the iPhone, Andriod, Windows etc. for the web sites I create
EDIT: I know it is an favicon but i Wanna know how to add it and how to use it in my website.
EDIT2: I did not try anything before because I am a starting developer
You most certainly did not try to search anywhere, within 10 seconds on google, I found an answer:
<link rel="icon" type="image/png" href="http://example.com/myicon.png">
