问题 On my website, i got the background image to stay always centered and the navigation to always stay on the same spot horizontally, so it does not matter the HORIZONTAL size, it's always on the same spot i did that by using: #nav { list-style: none; position:fixed; right:50%; margin-right:155px; margin-top:220px; } My issue is with the VERTICAL part.

问题 I have a mat-tab-nav-bar navigation bar for my website, but the mat-tab-link blue underlining bar won't chase the active button. It just stays at the first button, and doesn't move. The buttons do turn into active state though in the sense that the background color changes, and they route well to their corresponding pages.
