In Chrome, after a selection is performed by the user there is no extra visual sign that a selection is made. I mean after the selection is done, bg color-font color-size-family doesn't change for example.
If there are lots of select elements then it's useful to show the user that a selection is made. (my case)
I tried option:selected however this doesn't affect the outlook of select after it's selected and closed again.
I also tried select:after with content="✔" (tried to print a check mark) This effort did nothing.
How is this aim can be achieved by pure CSS?
