Theming - Help - I have a superposition of the eye (to see password clearly) and the arrow

Hello everybody,
Can you help me ?

I have a problem with my theme (theming) migrate owncloud 7.X toward owncloud 9.1.4.

My css does a bad thing, it put over the top the eye below arrow and we can clic to validate.

Could you help me to debug my CSS please ?

This is trace between example styles.css and my css :

Thank you
