السلام عليكم ..
أواجه مشكلة في تطبيق style css على بيانات مستدعاة من قاعدة بيانات لتشكل شجرة عائلة متتالية (الجد ثم الأبناء ثم الأحفاد ...إلخ)
يوجد خطأ فيما يبدو عند الابتداء بحلقة التكرار .. هذا مثال عن الشكل الصحيح والخاطئ عند تطبيق css
وهذا مثال عن الكود :
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="x-ua-compatible" content="ie=edge">
<title>شجرة عائلة</title>
<meta name="description" content="">
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
* {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*/

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;

}
/*Time to add downward connectors from parents*/

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 {
