How to program the invalidity of the password input field when the length is less than X in the CSS framework "Materialize CSS"?

Question

css

I can’t figure out how to make it so that, for example, if the password is less than 8 characters long, the line should light up in red. I didn't find any JQuery event to change the validity/invalidity of the text field.

Answer 1

By default, it can only keep track of the maximum length specified in the length attribute.
