searchbar not clickable

I edited/created css to overlap the sitemap logo:

#main {
padding: 10px 0 10px;
}
#site-logo {
float: left;
margin-top: -60px;
margin-bottom: 15px;
background: url(http://www.visionbuilders.com.ph/malltestWP/wp-content/uploads/2013/09/vcentral-malls-v2-04-lores2.png) center no-repeat;
background-size: contain;
width:100%;
max-width: 100%;
height: 100px;
padding-top: 10px;
padding-bottom: 10px;
}

.hgroup-wrap {
padding-top: 0px;
padding-bottom: 0px;
margin-top: 100px;

}

h1 a {
display: block;
text-indent: -9999px;
float: left;
}

#site-description {
font: 20px ‘PT Sans’, sans-serif;
line-height: 20px;
color: #777;
