Question

I’m using CSS style display:block and none for hiding a div based on a condition:
If facebook has been blocked display fb_Blockedwizard else display fb_wizard.

When I am loading or refreshing the page the div fb_Blockedwizard is displayed for a few second then the div gets hidden.

I need to hide the div during the load or refresh of the page

Below is the code which I’m using:

<script>
  $(document).ready(function() {
    hideFbBlockedwizard();
    hidefbwizard();
    var callbackOnSuccess = function(src) {
      hideFbBlockedwizard();
      showwizard();
      return false;
    };
    var callbackOnFailure = function(src) {
      hidefbwizard();
      showFbBlockedwizard();
    };
    checkAvailability("http://www.facebook.com/favicon.ico", 
      callbackOnSuccess,callbackOnFailure);
  });

  function  showFbBlockedwizard() {
    document.getElementById('fb_Blockedwizard').style.display='block';
    document.getElementById('fade').style.display='block';
  }   

  function hideFbBlockedwizard() {  
    document.getElementById('fb_Blockedwizard').style.display='none';
    document.getElementById('fade').style.display='none';
  }

  function checkAvailability(src, callbackSuccess, callbackFailure) {
    $("<img/>").attr("src", src).load(function() {
      callbackSuccess(src);     
  }).error(function() {
    callbackFailure(src);
  });
}

function showwizard() {
  document.getElementById('fb_Blockedwizard').style.display='none';
  document.getElementById('fb_wizard').style.display='block';
  document.getElementById('fade').style.display='block';    
}

Here my CSS:

.white_content {
        /*display: none;*/
        display:none;
        position: absolute;
        top: 25%;
        left: 25%;
        width: 46%;
        height: 37%;
        padding: 16px;
        border: 16px solid #999;
        background-color: white;
        z-index:1002;
        overflow: auto;
}
.white_content1 {
        display:none;
        position: absolute;
        top: 13%;
        left: 18%;
        width: 60%;
        height: 63%;
        padding: 16px;
        border: 16px solid #999;
        background-color: white;
        z-index:1002;
        overflow: auto;
}

Here my PHP:

  <div id="fb_wizard" class="white_content">
  <?php include  'fb_blocked.php'; ?>
  </div>
  <div id="fb_Blockedwizard" class="white_content1">
         <?php include  'fb_blocked_email.php'; ?> </div>

Is fb_Blockedwizard part of your layout? If so then give it directly the style display:none within HTML/CSS. Set it to display:block per javascript.
