The menu icon on the rig

Answer 1

The solution used by Twitter Bootstrap is using spans to construct the Hamburger:

The corresponding CSS is:

.navbar-toggle {
   position: relative;
   float: right;
   padding: 9px 10px;
   margin-top: 8px;
   margin-right: 15px;
   margin-bottom: 8px;
   background-color: #cccccc;
   border: 1px solid transparent;
   border-radius: 4px;
}

.navbar-toggle .icon-bar {
   display: block;
   width: 22px;
   height: 2px;
   background-color:#000000;
   border-radius: 1px;
}

.navbar-toggle .icon-bar+.icon-bar {
   margin-top: 4px;
}
