css:

body {     width: 960px;     margin: 0 auto; } header {     margin: 60px 0 40px; } .logo {     height: 162px;     width: 162px;     background-color: #9bd1af;     position: absolute;     top: 5px;     left: 50%;     margin-left: -81px;     z-index: 1;     -webkit-border-radius: 80px;     -moz-border-radius: 80px;     border-radius: 80px; } .line {     width: 100%;     height: 10px;     top: 6px;     position: relative;     background-color: #7e5a3a; } nav {     width: 100%;     text-transform: uppercase; } nav ul {     margin: 0;     padding: 0;     list-style-type: none;     text-align: center; } nav ul li {     display: inline;     background: #2d4c4e;     padding: 10px 20px; } nav ul li.empty {     padding: 10px 59px; } nav ul li {     padding: 3px 10px;     color: #f9eec6;     background: #2d4c4e;     -webkit-border-radius: 10px;     -moz-border-radius: 10px;     border-radius: 10px;     text-decoration: none; } nav ul li a:hover {     background-color: #7e5a3a;     color: #fff; }

i found new problem again when post code @ http://jsfiddle.net/g8ssp/ logo not in place want when size of browser narrowed

.logo { height: 162px; width: 162px; background-color: #9bd1af; position: absolute; top: 5px; left: 50%; margin-left: -81px; z-index: 1; -webkit-border-radius: 80px; -moz-border-radius: 80px; border-radius: 80px; }

change this: 

.logo { height: 162px; width: 162px; background-color: #9bd1af; position: relative; top:68px; left: 48%; margin-left: -81px; z-index: 1; -webkit-border-radius: 80px; -moz-border-radius: 80px; border-radius: 80px; }

the above logo being in place time! , space between list items disappear:

nav ul li { display: inline; background: #2d4c4e; padding: 10px 20px; margin-right:-7px;  }

putting negative margin-right soves problem.
