CSS Question

Family Tree CSS

Is there a way to get a child element to follow its parent?

The problem is that if there is only one child and the parent has a huge text to it, the position of the connector becomes really bad.
How can I fix it?

Fiddle demo



* {margin: 0; padding: 0;}

.tree ul {
padding-top: 20px; position: relative;
transition: all 0.5s;
-webkit-transition: all 0.5s;
-moz-transition: all 0.5s;
}

.tree li {
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 #ccc;
width: 50%; height: 20px;
}
.tree li::after{
right: auto; left: 50%;
border-left: 1px solid #ccc;
}

/*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 #ccc;
border-radius: 0 5px 0 0;
-webkit-border-radius: 0 5px 0 0;
-moz-border-radius: 0 5px 0 0;

border-radius: 5px 0 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 #ccc;
width: 0; height: 20px;
}

.tree li a{

-moz-border-radius: 5px;
transition: all 0.5s;

-moz-transition: all 0.5s;
}

/*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: #c8e4f8; color: #000; border: 1px solid #94a0b4;

/*Connector styles on hover*/

Answer

Change from float:left to display: inline-block in your .tree li rule

/*Now the CSS*/
* {margin: 0; padding: 0;}

.tree ul {
	padding-top: 20px; position: relative;
	transition: all 0.5s;
	-webkit-transition: all 0.5s;
	-moz-transition: all 0.5s;
}

.tree li {
  display: inline-block;
	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 #ccc;
	width: 50%; height: 20px;
}
.tree li::after{
	right: auto; left: 50%;
	border-left: 1px solid #ccc;
}

/*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 #ccc;
	border-radius: 0 5px 0 0;
	-webkit-border-radius: 0 5px 0 0;
	-moz-border-radius: 0 5px 0 0;
}
.tree li:first-child::after{
	border-radius: 5px 0 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 #ccc;
	width: 0; height: 20px;
}

.tree li a{
	border: 1px solid #ccc;
	padding: 5px 10px;
	text-decoration: none;
	color: #666;
	font-family: arial, verdana, tahoma;
	font-size: 11px;
	display: inline-block;
	
	border-radius: 5px;
	-webkit-border-radius: 5px;
	-moz-border-radius: 5px;
	
	transition: all 0.5s;
	-webkit-transition: all 0.5s;
	-moz-transition: all 0.5s;
}

/*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: #c8e4f8; color: #000; border: 1px solid #94a0b4;
}
/*Connector styles on hover*/
.tree li a:hover+ul li::after, 
.tree li a:hover+ul li::before, 
.tree li a:hover+ul::before, 
.tree li a:hover+ul ul::before{
	border-color:  #94a0b4;
}
