It should be content: attr(title);, not content: attr(data-title); - you don't have a data attribute.

它应该是内容：attr（标题）;而不是内容：attr（数据标题）; - 您没有数据属性。

Also, it seems ::before and ::after pseudo-elements are not defined for img - you may have to use something else:
CSS Content attribute for IMG tag

此外，似乎::之前和::之后的伪元素没有为img定义 - 您可能必须使用其他东西：IMG标签的CSS内容属性
