Can somebody please explain me the function of favicon.ico - what it does and why do we need it. If these theme has been handled before all my apologies didnt see it anywhere.

The function is identification. Not only does it show up well beside your website in a list of bookmarks, but it also helps the vistor identify it in the nav bar as well.

favicon.ico is the little icon of the website you are visiting that appears next to their URL in the address bar of web browser.  For instance, this website display a small icon symbol of a letter C with some blue light rays radiating from the letter next to the URL.

If you are using a modern-day web browser (such as Firefox, Opera, Safari, etc), you will see it.  Older browser, such as Internet Explorer, does not use or show that small icon next to the URL.

If you are creating your own website, all you need is to put the “favicon.ico” image file in the home directory, and the browser will automatically locate it and display it.  If the “favicon.ico” file is not found, the browser will display a generic icon instead.

With reference to certain versions of Internet Explorer, the Favicon should display IF the user bookmarks the page. In other words, the “fav” in its name refers to the fact that it is displayed when the page is added to “favorites”.

Hey thanks guys - it was a great echo
