</html>I'm currently working on my first website but having trouble with persistent white space surrounding the header image.
Despite trying different strategies like adjusting margins and utilizing padding:0;display: block along with width:100%, I am still unable to remove the unwanted whitespace.
If someone could review the code and provide insights on what might be causing this issue, it would be greatly appreciated.
