我认为它是CSS中的编码图像,但为什么会这样做呢?节省空间是否可以阻止人们窃取图像?

它被称为data url,并且在此示例中包含GIF格式的图像。它为您节省了额外的HTTP请求,但只能用于较小的文件,因为某些浏览器限制了数据URL的大小。但它有缺点:缓存对这些图像不起作用。此外,目前浏览器支持不是很好(IE7缺乏支持,IE8将大小限制为32KB)。

这是减少HTTP请求。就个人而言,我不喜欢这种技术,因为维护和更新会更麻烦,而且图像无法同时下载。
答案 2 :(得分:1)
这是base64格式的gif的全部内容。将图像保存为浏览器中的文件同样容易,因此安全性不是原因,而是像其他人所说的那样保存额外的HTTP请求。
答案 3 :(得分:0)
它基本上是该图像的base64输出,它用于保存http请求并加快速度 我想如果你读到这个,你将获得所有需要的信息
