It appears your css is missing some code. If you add this it will automatically work –
.quote {
background: #fff;
border: 1px solid #ddd;
color: #888;
padding: 20px;
}
.quote-arrow {
background-image: url(images/quote-arrow.png);
background-position: center bottom;
background-repeat: no-repeat;
bottom: 1px;
display: block;
margin: 0 0 10px;
padding: 14px 0 0;
position: relative;
}
.quote-gray {
background: #eee;
border: 1px solid #ccc;
color: #333;
padding: 20px;
}
.quote-arrow-gray {
background-image: url(images/quote-arrow-gray.png);
background-position: center bottom;
background-repeat: no-repeat;
bottom: 1px;
display: block;
margin: 0 0 10px;
padding: 14px 0 0;
position: relative;
}
.quote-black {
background: #121212;
border: 1px solid #353535;
color: #fff;
padding: 20px;
}
.quote-arrow-black {
background-image: url(images/quote-arrow-black.png);
background-position: center bottom;
background-repeat: no-repeat;
bottom: 1px;
display: block;
margin: 0 0 10px;
padding: 14px 0 0;
position: relative;
}
.quote-black a {
