Organization chart using html and css - css

Question

In this organization chart, the spacing between the list elements become too large(ex. between name3 and name5, between name5 and name12, between name6 and name11). How can we reduce the spaces between them, so that it can be view in one page without horizontal scrolling. Please help with this
I have attached the code which I tried
* {
margin: 0;
padding: 0;
}
.img-quadrata {
border-radius: 50%;
width: 100px;
height: 100px;
}
.text-center {
margin-top: 10px;
font-size: 1.2em;
}
small {
text-align: center;
font-size: 0.8em;
text-decoration: none;
color: gray;
}
.tree {
text-align: center;
padding-left: 10px;
}
.tree ul {
display: block;
white-space: nowrap;
padding-top: 15px;
position: relative;
transition: all 0.5s;
-webkit-transition: all 0.5s;
-moz-transition: all 0.5s;
}
.tree li {
vertical-align: top;
display: inline-block;
white-space: normal;
text-align: center;
list-style-type: none;
position: relative;
padding: 20px 0px 0px 60px;
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: 60%;
height: 15px;
}
.tree li::after {
right: auto;
left: 50%;
border-left: 1px solid #ccc;
}
/*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*/
ul.first li.first::before,
ul.first li.first::after {
border: 0 none;
}
.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: 15px;
}
