My client wants a custom header transition on his website like this one: https://www.laureloakwealth.com/
Currently I have white text and the header doesn’t have background color and on scroll the background changes to a white color, but the white text gets lost. I want it so that when you scroll, the text in header would change to a darker color, like a dark blue, to have better contrast. Is there specific code that can help with this effect?
