Dynamic Tab In Salesforce ( CSS and apex:dynamicComponent )


Some time we need to create dynamic tab. This we can achieve with below way :-
1) By CSS
2) By <apex:dynamicComponent


DEMO 1:- By CSS 

Page :-

<apex:page controller="DynamicTabController" sidebar="false"  standardStylesheets="false" showHeader="false">
<head>
 <style type="text/css">

 .black_overlay{
       display: none;
       position: absolute;
       top: 0%;
       left: 0%;
       width: 100%;
       height: 100%;
       background-color:#F8F8F8  ;
       z-index:1001;
       -moz-opacity: 0.8;
       opacity:.80;
       filter: alpha(opacity=80);
  }
  .white_content {
      display: none;
      position: relative;
      z-index:1002;
      overflow: auto;
  }

    #layer1 
                {
                position: absolute;
                visibility: hidden;
                width: 800px;
                height: 450px;
                left: 50%;
                top: 20%;
                background-color: #ccc;
                border: 1px solid #000;
                padding: 10px;
                overflow:scroll;
               }
            
            #close 
            {
                float: right;
            } 

 
.tabs {
  position: relative;   
  min-height: 550px; /* This part sucks */
  clear: both;
  margin: 25px 0;
}
.tab {
  float: left;
}

  background: #eee; 
  padding: 10px; 
  border: 1px solid #ccc;

  border-bottom: 1px solid white;
  z-index: 2;
