title: How to extend a CSS family tree horizontally?
body: <p>I have created a family tree using CSS.</p>
  
  <p><a href="https://i.stack.imgur.com/HRieg.png" rel="noreferrer"><img src="https://i.stack.imgur.com/HRieg.png" alt="enter image description here"></a></p>
  
  <p>The family tree works properly but the problem is that if there are too many lists in a row, it breaks the row at the right end of the line, and displays it on a new line.</p>
  
  <p>How do I make this family tree extend horizontally without breaking the child elements? Even if I do not have a horizonal scroll at the bottom of the page, I just want to display this tree as is - without moving elements into a new line.</p>
  
  <p>This is the code:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.tree ul {
    overflow-x: auto;
    padding-top: 20px; position: relative;
    
    transition: all 0.5s;
    -webkit-transition: all 0.5s;
    -moz-transition: all 0.5s;
  }
  
  .tree li {
    overflow-x: auto;
    float: left; text-align: center;
    list-style-type: none;
    position: relative;
    padding: 20px 5px 0 5px;
    
    transition: all 0.5s;
    -webkit-transition: all 0.5s;
    -moz-transition: all 0.5s;
  }
  
  /*We will use ::before and ::after to draw the connectors*/
  
  .tree li::before, .tree li::after{
    content: '';
    position: absolute; top: 0; right: 50%;
    border-top: 1px solid #F39331;
    width: 50%; height: 20px;
  }
  .tree li::after{
    right: auto; left: 50%;
    border-left: 1px solid #F39331;
  }
  
  /*We need to remove left-right connectors from elements without 
  any siblings*/
  .tree li:only-child::after, .tree li:only-child::before {
    display: none;
  }
  
  /*Remove space from the top of single children*/
  .tree li:only-child{ padding-top: 0;}
  
  /*Remove left connector from first child and 
  right connector from last child*/
  .tree li:first-child::before, .tree li:last-child::after{
    border: 0 none;
  }
  /*Adding back the vertical connector to the last nodes*/
  .tree li:last-child::before{
    border-right: 1px solid #F39331;
    border-radius: 0 5px 0 0;
    -webkit-border-radius: 0 5px 0 0;
    -moz-border-radius: 0 5px 0 0;
  }

    -webkit-border-radius: 5px 0 0 0;
    -moz-border-radius: 5px 0 0 0;
  }
  
  /*Time to add downward connectors from parents*/
  .tree ul ul::before{
    content: '';
    position: absolute; top: 0; left: 50%;
    border-left: 1px solid #F39331;
    width: 0; height: 20px;
  }
  
  .tree li a{
    border: 1px solid #0F60AF;
    background-color: #0F60AF;
    padding: 5px 10px;
    text-decoration: none;
    color: #fff;
    font-family: arial, verdana, tahoma;

    -moz-transition: all 0.5s;
  }
  
  bg_orange {
    border: 1px solid #F39331;
    background-color: #F39331;
  }
  
  /*Time for some hover effects*/
  /*We will apply the hover effect the the lineage of the element also*/
  .tree li a:hover, .tree li a:hover+ul li a {
    background: #F39331; color: #fff; border: 1px solid #F39331;
