如何为网站添加浏览器选项卡图标（favicon）？ [英] How to add a browser tab icon (favicon) for a website?
问题描述
我如何在HTML中执行此操作，并在何处执行此操作在代码中我需要放置它（例如标题）？我有一个 .png 徽标文件，我想将它转换为图标。
相关：浏览器标签上的HTML设置图片。
< / p> link rel =icon>
只需将以下代码添加到< head> 元素：
< link rel =iconhref =http ：//example.com/favicon.png>
PNG图标受大多数浏览器支持，但IE <= 10 除外。为了向后兼容，您可以使用ICO图标。
请注意，您不必先于图标在 rel 属性中使用快捷键 。从 MDN链接类型：
在
图标之前经常出现快捷键链接类型，但这种链接类型是不符合的，被忽略，并且网络作者不能再使用它了。
favicon.ico 在根目录中
所有现代浏览器（经过Chrome 4，Firefox 3.5，IE8，Opera 10和Safari 4测试）都会请求
favicon.ico，除非您通过< link>指定了快捷图标。
$ b $所以你所要做的就是让你的网站的 /favicon.ico 请求返回你的图标。不幸的是，这个选项不允许你使用PNG图标。
另见 favicon.png vs favicon.ico - 为什么我应该使用PNG而不是ICO？
I've been working on a website and I'd like to add a small icon to the browser tab.
How can I do this in HTML and where in the code would I need to place it (e.g. header)? I have a .png logo file that I'd like to convert to an icon.

There are actually two ways to add a favicon to a website.
<link rel="icon">
Simply add the following code to the <head> element:
<link rel="icon" href="http://example.com/favicon.png">
PNG favicons are supported by most browsers, except IE <= 10. For backwards compatibility, you can use ICO favicons.
Note that you don't have to precede icon in rel attribute with shortcut anymore. From MDN Link types:
The
shortcutlink type is often seen beforeicon, but this link type is non-conforming, ignored and web authors must not use it anymore.
favicon.ico in the root directory
From another SO answer (by @mercator):
All modern browsers (tested with Chrome 4, Firefox 3.5, IE8, Opera 10 and Safari 4) will always request a
favicon.icounless you've specified a shortcut icon via<link>.
So all you have to do is to make the /favicon.ico request to your website return your favicon. This option unfortunately doesn't allow you to use a PNG icon.
