Can't enable Dark Mode for the forum

It doesn’t wheter I click Dark Mode or Light Mode, it remains with Whie and Green design :frowning:

That’s weird. Seems the “dark theme” is the same as the light theme.

You can try changing the styles with a stylesheet editor extension, such as Stylebot for Chrome. Then, set the site CSS to this:

body, .menu-panel, .notifications *, .user-stream * {
    background: #222;
    color: #aaa;
}

a {
    color: #eee;
}

.btn {
    background: black;
    color: #aaa;
}

.btn:hover {
    color: #fff;
}

.main-nav a:hover, #navigation-bar a:hover, .d-header-icons a:hover {
    color: #000;
}

.primary-textual, .topic-map {
    background: #444;
}

#reply-control, #reply-control textarea, #reply-control input, .d-editor-button-bar {
    background: black;
    color: #aaa;
}

You can change the individual styles to get them how you like.
