I submitted all my projects and they are all working perfectly …
In the technical documentation project I have used ( overflow : scroll ) for my navbar-container when it hits 800px…the scroll is working well but I cant see any scroll bar to control it , I can only use the scroll button on my mouse and slide in mobile layout …I want to see my scrollbar
I have reviewed the whole curriculum and there was no lesson on this topic
I didnt go for google search yet , I thought the community is much better for providing sufficient details
I have never tried making a custom scroll bar but you could look into css tricks. They have really good resources and might be able to provide you with the information you need.
