问题
I have a few static pages that are just pure HTML, that we display when the server goes down. How can I put a favicon that I made (it\'s 16x16px and it\'s sitting in the same directory as the HTML file; it\'s called favicon.ico) as the \"tab\" icon as it were? I have read up on Wikipedia and looked at a few tutorials and have implemented the following:
<link rel=\"icon\" href=\"favicon.ico\" type=\"image/x-icon\"/>
<link rel=\"shortcut icon\" href=\"favicon.ico\" type=\"image/x-icon\"/>
But it still doesn\'t want to work. I am using Chrome to test the sites. According to Wikipedia .ico is the best picture format that runs on all browser types.
Update
I could not get this to work locally although the code checks out it will only really work properly once the server started serving the site. Just try pushing it up to the server and refresh your cache and it should work fine.
回答1:
You can make a 16x16 .png and then use one of the following snippets between the <head> tags of your static HTML documents:
<link rel="shortcut icon" type="image/png" href="/favicon.png"/>
<link rel="shortcut icon" type="image/png" href="http://example.com/favicon.png"/>
回答2:
Most browsers will pick up favicon.ico from the root directory of the site without needing to be told; but they don't always update it with a new one right away.
However, I usually go for the second of your examples:
<link rel='shortcut icon' type='image/x-icon' href='/favicon.ico' />
回答3:
Actually, to make your favicon work in all browsers, you must have more than 10 images in the correct sizes and formats.
I created an App (faviconit.com) so people don´t have to create all these images and the correct tags by hand.
Hope you like it.
回答4:
The following works for me...
<link rel="shortcut icon" type="image/x-icon" href="favicon.ico" />
回答5:
Convert your image file to Base64 string with a tool like this and then replace the YourBase64StringHere placeholder in the below snippet with your string and put the line in your HTML head section:
<link href="data:image/x-icon;base64,YourBase64StringHere" rel="icon" type="image/x-icon" />
This will work 100% in browsers.

Usage Syntax: .ico, .gif, .png, .svg
This table shows how to use the favicon in major browsers. The standard implementation uses a link element with a rel attribute in the section of the document to specify the file format and file name and location.
Note that most browsers will give precedence to a favicon.ico file located in the website's root (therefore ignoring any icon link tags).

Icon files can be 16×16, 32×32, 48×48, or 64×64 pixels in size, and 8-bit, 24-bit, or 32-bit in color depth.
While the information above is generally correct, there are some variations/exceptions in certain situations.

If the favicon is a png type image, it'll not work in older versions of Chrome. However it'll work just fine in FireFox. Also, don't forget to clear your browser cache while working on such things. Many a times, code is just fine, but cache is the real culprit.
回答8:
As recommended by W3.org, you can use the rel attribute to achieve this.
Example:
<head>
<link rel="icon"
type="image/png"
href="http://example.com/myicon.png">

<link rel="shortcut icon" type="image/png" href="/favicon.png"/>
<link rel="shortcut icon" type="image/png" href="http://example.com/favicon.png"/>
回答10:
<link rel="shortcut icon" type="image/png" href="/favicon.png"/>

I know its older post but still posting for someone like me. This worked for me
<link rel='shortcut icon' type='image/x-icon' href='favicon.ico' />

回答12:
as an additional note that may help someone some day.
You can not echo anything to the page before:

<link rel="shortcut icon" type="image/ico" href="/webico.ico"/>

<link rel="shortcut icon" type="image/ico" href="/webico.ico"/>
<link rel="shortcut icon" type="image/ico" href="/webico.ico"/>
Hello

I used convert -resize 16x16 img.png favicon.ico (on linux konsole) to convert my image, and
add <link rel="icon" href="images/favicon.ico" type="image/png" sizes="16x16"> to my header and everything work perfect.
回答14:
Notice that if your site is running as a subfolder ie:
http://localhost/MySite/
You will need to take that into account. If you are doing so from an ASP.NETapp all you need to do is add a ~ to the front of the URL:
<link rel="shortcut icon" type="image/x-icon" href="~/favicon.ico" />
回答15:
If you add the favicon into the root/images folder with the name favicon.ico browser will automatically understand and get it as favicon.I tested and worked. your link must be www.website.com/images/favicon.ico

Do you have to include <link rel="icon" href="favicon.ico" type="image/x-icon" />?
回答16:
Note that FF fails to load an icon with a redundant // in URL like /img//favicon.png. Tested on FF 53. Chrome is OK.
回答17:
Try to use the <link rel="icon" type="image/ico" href="images/favi.ico"/>
