What exactly need for a full scren height slider section?

height: 100vh;
width: 100%;
background-image url(’’);
need position?

Still any idea?

Not understanding what you are needing help with. Is this a personal project or an FCC challenge? In either case, can you provide a link to the entire project if it is a project, or provide all the code you have tried and the challenge name if it is an FCC challenge?
