问题
I was trying to add a favicon to a website earlier and looked for a better way to implement this than to dump a favicon.ico file in the root of the website.
I found this nice little guide: How to Add a Favicon. However, the preferred method did not work in IE (7) and the second method is the old fashioned way (which I resigned myself to use).
Is there a third method that works across all the most popular browsers?
回答1:
This is what I always use:
<link rel="icon" href="favicon.ico" type="image/x-icon" />
<link rel="shortcut icon" href="favicon.ico" type="image/x-icon" />
The second one is for IE. The first one is for other browsers.
回答2:
You can use HTML to specify the favicon, but that will only work on pages that have this HTML. A better way to do this is by adding the following to your httpd.conf (Apache):
AddType image/x-icon .ico
回答3:
I think the most reliable method is the simply added the favicon.ico file to the root of your website.
I don't think there is any need for a meta tag unless you want to manually override the default favicon, but I was unable to find any research to support my argument.

This is how they're doing it right here on Stack Overflow:
<link rel="shortcut icon" href="/favicon.ico" />

Well, the file is in the root so it does not show whether the tag works or if the browser just got the icon from the usual location (the root).
Edit: I'll try it and see if it works.
Edit 2: Using both tags make it work even for any file name as long as the file is an icon for IE7: I tried using .png files and it only worked with Firefox.

There are a million different ways these icons are used (different browsers, different platforms, mobile site-pinning, smart TVs, etc, etc), so there's really no longer a simple answer. For a great explanation see this S.O. answer, but the short answer is:
Use this site which lets you upload a png/jpg and then does all the hard work for you: https://realfavicongenerator.net/
