Tab Section Format Problem

I added a Tab Section to the page listed in Private Content and it is totally unformatted. I am wondering if there is a quick css that could be effecting it. below is what I have in my quick css.

.slide-meta { display: none; }

.fake-thumbnail .slide-image{
display: none;
}

.news-thumb {
display: none;
}

span.news-time {
display: none;
}

.main_color table caption, .main_color tr:nth-child(even), .main_color .pricing-table>li:nth-child(even) {
color: inherit!important;
}

.main_menu ul:first-child > li > a { padding: 0 20px!important; }

.content {
border: none;
}

.content, .sidebar { padding-top: 50px; padding-bottom: 10px; }

.avia-post-nav {
display: none !important;
}

td { border-style: none; }
tr:first-child td { border-top-style: none; }
tr td:first-child { border-left-style: none; }
.alternate_color tr:nth-child(odd) { background: #111111; }

.content, .sidebar { padding-top:40px; padding-bottom: 10px; }

@media only screen and (max-width: 767px) {
.responsive #top #wrap_all .container {
width: 95%;
max-width: 95%;
}
}

div#header_main_alternate {
min-height: 38px;
}

#main>.fullsize>.container>.content {
padding-top: 0;
}

.av-masonry-entry .av-masonry-entry-title {
margin: 0;
font-size: 12px;
color: ;
}
