Header background image just stopped working
Your tag is using 2 identifiers instead of one id=”masthead masthead_custom” class=”masthead_custom” id=”masthead” will correct your problem. #masthead.masthead_custom { background-image: url(“./bg.jpg”); background-color: #444; height: 100vh; background-position: center; background-repeat: no-repeat; background-size: cover; opacity: 0.6; position: relative;; z-index: 999999; } Tell me if it works.
