fixed header displayed over content, but there is a gap at the top,
问题 so I have fixed and centered the header, and the z-index achieves it being over the top of content that scrolls, however there is a small gap at the top. I tried using overflow:auto but it did not work as I had hoped. <body> <div class="wrapper"> <header class="site-header delay fadeInDown animated"> <a class="header-link fadeInDown animated" href="/"> <h1>BryanBell</h1> </a> </header> CSS h1 { font-family:"CubanoRegular"; font-size:72px; letter-spacing:12pt; line-height:120%; text-align
