Change Css on action

[Sahar-magh]

Is it possible to change css of the fa-icon after clicking on it ? I would love to mark a main selected item through an action on Fa icon.
This doesn't work
.action:visited { color: blue; } thank you :

visited might not work if it's not an a element. You might wanna try :active. Based on your use case, this may give you some pointers https://codepen.io/andreinacio/pen/doKGjP
