解答：

alt 是图片加载失败时，显示在网页上的替代的文字；
title 是鼠标放上面时显示的文字。
这些都是表面上的区别，alt是img必要的属性，而title不是。

还可以从seo的角度上做区别

Answer:

Alt is the alternate text that appears on the page when the image fails to load.
Title is the text displayed when the mouse is over it.
These are all superficial differences, Alt is a necessary attribute of img, and title is not.
