My user CSS wrote on top the "broken" sprucey theme.
You probably need only the first two blocks.
Maybe the others if you like what they does.
Need auto-hide header mod off as is not covered here.
/* Fix sprucey header/menu */
#vivaldi-header {background: #2e3539;}
#vivaldi-header a, #vivaldi-header a:visited {color: #fff;}
#vivaldimenu a.current {color: #ff0e00;}
/* Fix poor contrast areas */
.topic .posts>li .post-footer a,
.topic .posts>li .post-header a,
.breadcrumb a {color: #24948c;}
.topic .posts>li .post-footer a:hover,
.topic .posts>li .post-header a:hover,
.breadcrumb a:hover,
.chat-modal .chat-content li.chat-message
.message-body-wrapper:hover .message-body,
div[widget-area=header] a {color: #30c3b9;}
.navbar-default .navbar-toggle:hover,
.navbar-default .navbar-toggle:focus {background-color: #211;}
/* Compact threads */
li[component="post"] {
border-bottom: 1px solid !important;
border-radius: 0px !important;
margin-bottom: 1px !important;
}
.container {width: 99% !important;} /*more space*/
/* Hide best posts */
.col-lg-6 {width: 100% !important;}
.col-lg-6:first-of-type {display: none;}
/* Hide deleted posts */
/*li.deleted[component="post"]{display: none;}*/
/* I like necro-ing (a bit) */
.necro-post {display: none;}
