Why does:visited not work in css?

1. The order may be different

css definition of the four states of hyperlinks is also in order

a:link {} /* 未访问的链接 */
a:visited {} /* 已访问的链接 */
a:hover {} /* 当有鼠标悬停在链接上 */
a:active {} /* 被选择的链接 */

There is a little need for the settings of these four pseudo-classes Pay special attention to their order, and make them follow a sequence principle, that is, link ~ visited ~ hover ~ active. If you get the order wrong, unexpected errors will occur. If you are a beginner, you can practice it in private.

2. It is possible that the link in a href is invalid.

The invalid link will invalidate the visited setting of a. This is because there is no history of web page visits after clicking the link, so the link is invalid after clicking.

  a:visited   {color: #FFFF00;  text-decoration:none;}
