Hi,
Kindly remove the code provided above.
This is the one causing the issue.
/*navbar bgd gradien*/
.x-navbar {
height: 80px;
background: /* Permalink - use to edit and share this gradient: http://colorzilla.com/gradient-editor/#395c7f+0,5498bc+100 */
background: #395c7f; /* Old browsers */
background: -moz-linear-gradient(top, #395c7f 0%, #5498bc 100%); /* FF3.6-15 */
background: -webkit-linear-gradient(top, #395c7f 0%,#5498bc 100%); /* Chrome10-25,Safari5.1-6 */
background: linear-gradient(to bottom, #395c7f 0%,#5498bc 100%); /* W3C, IE10+, FF16+, Chrome26+, Opera12+, Safari7+ */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#395c7f', endColorstr='#5498bc',GradientType=0 ); /* IE6-9 */
}
Change height: 80px; to height: auto;
Hope that helps.
