avf_logo_subtext missing styles, JavaScript

Dear Kriesi.at!

Congratulations for this very easy-to-use and awesome theme. Especially the plentiful examples are useful.

I would like to use the avf_logo_subtext filter, and realized that the related css styles and the hide effect JS code are missing. I have already hunted for styles around your site, and included the following items into the custom.css, but could you please help me with a proper solution? Thank you.

.logo, .logo a {
    overflow: visible;
}

#top .logo img {
    float: left;
}

#top .subtext {
    float: left;
    position: relative;
}

#top .logo-title {
    color: #444444;
    font-size: 12px;
    left: 7px;
    opacity: 1;
    position: absolute;
    top: -7px;
    transition: opacity 0.4s ease-out 0s;
    white-space: nowrap;
}

#top .logo-subtitle {
    color: #AAAAAA;
    top: 7px;
}

.responsive #top .logo-title {
    opacity: 0;
}
