这是正确的想法。增加了与大多数浏览器兼容的解决方案：https://stackoverflow.com/a/44710590/1667977 – sm4

创建一个脚本将其插入到图像中。我故意把脚本代码内联，因为你要发送一个HTML文件：

<img alt="pdf"/>

    var images = document.getElementsByTagName('img');

应用程序是困难。我可以在JQuery中完成，但我不想要任何库或单独的文件。 –

更新了我的回答@ Devil'sAdvocate。只是另一种方法。 – Brett84c

这是我期待的，谢谢你的更新。但我更喜欢CSS解决方案。 –

对方回答使用CSS提供了正确的想法，但它与所有浏览器不兼容。 CSS的content属性只允许在伪元素::before和::after中。带有content属性的类的img标记为空。浏览器没有义务显示它。 Chrome仍然显示它（不正确）。

为了使这项工作对于所有浏览器，在一个空的跨度使用例如::before：

span.word-icon::before {
