What do you want to achieve? This line is a little bit strange for me, because either you want a background color of not.
background: none repeat scroll 0 0 #388694;
Here some examples for several background properties.
No background:
background: transparent;
One color background:
background: #000000;
CSS gradient background:
background: #45484d; /* Old browsers */
background: -moz-linear-gradient(top, #45484d 0%, #000000 100%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#45484d), color-stop(100%,#000000)); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(top, #45484d 0%,#000000 100%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(top, #45484d 0%,#000000 100%); /* Opera 11.10+ */
background: -ms-linear-gradient(top, #45484d 0%,#000000 100%); /* IE10+ */
background: linear-gradient(to bottom, #45484d 0%,#000000 100%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#45484d', endColorstr='#000000',GradientType=0 ); /* IE6-9 */
