html5 – 最小可行Favicon代码

我对在大多数手机和浏览器上使用favicons最简单的方式感到困惑.

1)Some sites建议使用足够的：

<link rel="apple-touch-icon-precomposed" href="apple-touch-icon-180x180.png">

这将适用于iOS 8,应由Android,BlackBerry,Windows等提取.

2)Other sites坚持要明确规定每一个可能的图标：

<link rel="apple-touch-icon" sizes="57x57" href="/apple-touch-icon-57x57.png">
<link rel="apple-touch-icon" sizes="114x114" href="/apple-touch-icon-114x114.png">
<link rel="apple-touch-icon" sizes="72x72" href="/apple-touch-icon-72x72.png">
<link rel="apple-touch-icon" sizes="144x144" href="/apple-touch-icon-144x144.png">
<link rel="apple-touch-icon" sizes="60x60" href="/apple-touch-icon-60x60.png">
<link rel="apple-touch-icon" sizes="120x120" href="/apple-touch-icon-120x120.png">
<link rel="apple-touch-icon" sizes="76x76" href="/apple-touch-icon-76x76.png">
<link rel="apple-touch-icon" sizes="152x152" href="/apple-touch-icon-152x152.png">
<link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon-180x180.png">
<link rel="icon" type="image/png" href="/favicon-192x192.png" sizes="192x192">
<link rel="icon" type="image/png" href="/favicon-160x160.png" sizes="160x160">
<link rel="icon" type="image/png" href="/favicon-96x96.png" sizes="96x96">
<link rel="icon" type="image/png" href="/favicon-16x16.png" sizes="16x16">
<link rel="icon" type="image/png" href="/favicon-32x32.png" sizes="32x32">
<Meta name="msapplication-TileColor" content="#000000">
<Meta name="msapplication-TileImage" content="/mstile-144x144.png">

3)This answer说你只需要：

<!-- For IE 9 and below. ICO should be 32x32 pixels in size -->
<!--[if IE]><link rel="shortcut icon" href="path/to/favicon.ico"><![endif]-->

<!-- Touch Icons - iOS and Android 2.1+ 180x180 pixels in size. --> 
<link rel="apple-touch-icon-precomposed" href="apple-touch-icon-precomposed.png">

<!-- Firefox,Chrome,Safari,IE 11+ and Opera. 196x196 pixels in size. -->
<link rel="icon" href="path/to/favicon.png">

以上哪一项将以最少的努力来覆盖最多的浏览器/手机？

解决方法

解决方案3中的代码正确但过时. Precomposed Touch icons were deprecated in iOS 7和 Android Chrome does not support 196×196 icons anymore,but 192×192( it really won’t use anything above 192×192;全面披露：我是本文的作者).

所以：

<!-- For IE 9 and below. ICO should be 32x32 pixels in size -->
<!--[if IE]><link rel="shortcut icon" href="/path/to/favicon.ico"><![endif]-->

<!-- Touch Icons - iOS and Android 2.1+ 180x180 pixels in size. --> 
<link rel="apple-touch-icon" href="/path/to/apple-touch-icon.png">

<!-- Firefox,IE 11+ and Opera. 192x192 pixels in size. -->
<link rel="icon" href="/path/to/favicon.png">

如果您可以将favicon.ico放在网站的根目录下,您甚至可以跳过其声明,因为IE按惯例查找/favicon.ico.
