What is the name of this theme you use at this Mybb forum?

I believe either @sphinxc0re or @Mathias added the theme.

I noticed a css file called 'responsive.css' which might do the trick:

@media (max-width: 500px) {
     .author_statistics {
         width: 98%;
         padding-left: 0!important;
         padding-right: 0!important;
    }
}
 @media (max-width: 800px) {
     #logo {
         text-align: center;
    }
     #logo img {
         width: 70%;
         margin-bottom: 25px;
    }
     .wrapper {
         width: 100%;
         overflow-x: scroll;
    }
     .menu {
         text-align: center!important;
    }
     .menu a {
         padding-bottom: 5px;
    }
     tbody{
         min-width: 600px;
    }
     .widthstyle {
         width: 50%;
    }
     #morelinks {
         padding-top: 8px;
    }
     #panel .wrapper {
         margin-left: 5px;
    }
     .threadcount, .postcount, .viewcount, .forumviewers {
         display: none;
    }
     .showonmobile {
         display: block!important;
         font-style: italic;
         padding-top: 5px;
    }
     .showonmobilethreads {
         display: block!important;
         font-style: italic;
         padding-top: 2px;
         padding-bottom: 3px;
    }
}
 #container {
     min-width: 0px;
     width: 100%;
}
 .wrapper {
     min-width: 0px;
}
 .showonmobile {
     display: none;
}
