Simple CSS tabs - need to break border on active tab

Changing your existing code as little as possible - try display: inline-block for the li tags, with the border on a .menu container div:

.menu {
    border-bottom: 1px solid #666;
}
ul.tabHolder {
    overflow: hidden;
    margin: 1em 0 -2px;
    padding: 0;
}
ul.tabHolder li {
    list-style: none;
    display: inline-block;
    margin: 0 3px;
    padding: 3px 8px 0;
    background-color: #444;
    border: 1px solid #666;
    font-size: 15px;
}
ul.tabHolder li.active {
    background-color: #944;
    border-bottom-color: #944;
}

HTML used to illustrate (added div at bottom to show blending of active tab into div colour):

<div class="menu">
    <ul class="tabHolder">
        <li>Menu 1</li>
        <li class="active">Menu 2</li>
        <li>Menu 3</li>
    </ul>
</div>
<div style="background-color: #944; height: 1em">

ABOUT THE CODE Some lists within the Listamatic site had to be modified so that they could work on Listamatic's simple list model. When in doubt, use the external resource first, or at least compare both models to see which one suits your needs.


.tab {
  display: inline-block;
  background-color: #aaa;
  padding: 4px;
  border: 1px solid #888;
  border-bottom: none;
  
  position: relative;
  bottom:-1px;
  z-index: -1;
}

.tab-body {
  position: relative;
  height: 100px;
  width: 200px;
  padding: 4px;
  background-color: #ccc;
  border: 1px solid #888;
  z-index: 1;
}

.tab.active {
  background-color: #ccc;
  z-index: 2;
}
<div class="tab tab1">Tab 1</div>
<div class="tab tab2 active">Tab 2</div>
<div class="tab tab3">Tab 3</div>

<div class="tab-body">Tab Body</div>
