html - 在图像元素中显示 .ico

Question

我正在尝试在图像元素中显示 .ico，<img>但在 Internet Explorer 中它不起作用/显示。这是我的代码：

<img src="images.ico" >

有人如何让它出现在所有浏览器中？

Answer 1

在 img 标签中显示 ico 文件并不能保证在所有浏览器中都有效（我不推荐它）。如果要在 Web 上显示 ico 文件，请将其转换为另一种格式。

Answer 2

You can always put the base64 representation of an icon in the src attribute. It will look like this:

<img src="data:image/x-icon;base64,...">

where ... will be the base64 representation.

If you need a tool for conversion from icon to base64, you can use Base64.Guru encoder for example.

Here is the snippet with Google favicon encoded in the base64 representation:
