HTML Hints and Tips

Favourite Icon

Add the following to your HTML document <head> section:

<link rel="icon" href="favicon.ico" type="image/x-icon">
<link rel="shortcut icon" href="favicon.ico" type="image/x-icon">

Add favicon.ico to your server's root directory too. See How To Create And Install A favicon.ico which also describes using png2ico to convert a 16x16 pixel png image to ico format. Another option is to use The Gimp.
