I have a question about selecting or defining a CSS selector for the horizontal line in an Elementor divider widget. First of all, is this possible? I have tried standard selectors (div, hr, etc.) in addition to defining specific class and ID names (eg., my-class, my-id, etc.) and then using these definitions as selectors in CSS, but none of this works. What I would like to do is to have a divider line color change during scroll for use with a CSS sticky header. Does anyone have any ideas of how I might do this? Thank you!
