      <div class="well sidebar-nav left">         <ul class="nav nav-list">          <li class="divider"></li>  // <-- how stretch 100% outer container margins             <li class="nav-header">sidebar</li>           <li class="active"><a href="#">link</a></li>           <li><a href="#">link</a></li>           <li><a href="#">link</a></li>           <li><a href="#">link</a></li>         </ul>       </div><!--/.well -->              </div><!--/span-->   </div><!--/row-->                 

body { padding-top: 60px; padding-bottom: 40px; } .sidebar-nav {     padding: 9px 0; } .row-fluid > .sidebar-nav {     width: 220px; } .left {     float:left; } .divider {   border-top: 1px solid #000 !important;   border-bottom: 1px solid #000 !important;      } 

the padding comes ul list may try using div before list. stretch 100%.

html

<div class="well sidebar-nav left">     <div class="divider"></div>     <ul class="nav nav-list">         <li class="nav-header">sidebar</li>         <li class="active"><a href="#">link</a></li>         <li><a href="#">link</a></li>         <li><a href="#">link</a></li>         <li><a href="#">link</a></li>     </ul> </div> 

css

.divider {     border-top: 1px solid #000 !important;     border-bottom: 1px solid #000 !important;     height: 1px; } 

example fiddle

update

i think found better solution not need change in markup, can have li,divider anywhere in list. add css:

.nav-list {     padding: 0; } .nav-list > li > a, .nav-list .nav-header {     margin: 0; }
