A dark userstyle for https://lobste.rs that aims to be simple and robust.

lobsters-dark.css

body, textarea, input, button {
    font-size: 11px;
}

a {
    color: green;
}

p>a {
    color: green !important;
}


body {
    background-color: #202020;
    color: grey;
}

button, input, textarea {
    background-color: #303030 !important;
    color: lightgrey !important;
}

.comments, .story_text {
    color: lightgrey !important;
}

span.headerlinks > a,
span#headertitle > a,
span.comments_label > a,
div.details > div.byline > a,
div.details > div.byline > a.comment_editor, 
div.details > div.byline > a.comment_deletor,

.cur_url {

}
