How can I ensure that the div remains fixed on scroll and appears directly below the navigation bar, rather than at the top of the page?

There is a div (#callback) that loads asynchronously via ajax upon submit, for updating or deleting an item. It appears as the green message box at the top of the page. Click here to see image and this is how it looks when "scrolling": Check out the scrolling image here

I currently have it set to stay within the visible range of the screen with a "fix on scroll" effect. However, I don't want it to be fixed at the very top of the document unless the scroll offset reaches it. At that point, I want it to stay fixed while scrolling.

My goal is to position it just below the nav-bar instead of on top of it if the scroll offset hasn't reached it yet.

Below is the JavaScript code:

// Notification-Message Position
$(window).scroll(function(e){ 
    var el = $('#callback'); 
    if ($(this).scrollTop() > 200 && $el.css('position') != 'fixed'){ 
        $('#callback').css({'position': 'fixed', 'top': '0px'}); 
    }
    if ($(this).scrollTop() < 200 && $el.css('position') == 'fixed'){
        $('#callback').css({'position': 'static', 'top': '0px'}); 
    } 
}); //END Notification-Message Position

And here's the CSS code:

/*FIXED ON SCROLL*/
#callback{

    position: fixed;
    top: 0;
    width: 100%;
    z-index: 100;

}

Apologies for the basic question, as I'm still learning.

Answer №1

Here is a helpful code snippet to use:

$(window).scroll(function(e){ 
                var el = $('#callback'); 
                if ($(this).scrollTop() > 200 && $el.css('position') != 'fixed'){ 
                    $('#callback').css({'position': 'absolute', 'top': '0px'}); 
                }
                if ($(this).scrollTop() < 200 && $el.css('position') == 'fixed'){
                    $('#callback').css({'position': 'static', 'top': '0px'}); 
                } 
            }); //EN

Also, don't forget to add this CSS styling:

   /*FIXED ON SCROLL*/
#callback{
    position:absolute;
    top:0;
    width:100%;
    z-index:100;
}

Answer №2

Here's a suggestion: purely using CSS:

 #callback {
  height: 30px;
  position: fixed;
  right: 0;
  top: 0;
  width: calc(100% - 250px);
  z-index: 100;
   background:red;
}
<div style="height:560px" >
  <div style="float:left;margin:10px 10px 10px 0">
    <input type="submit" name="send_new" value="Send" class="send_button" />
  </div>
  <div id="callback">
    message
  </div>
  <div id="save_status" style="float:left;padding: 15px 0px;">sdd</div>
</div>

Consider updating your JavaScript code with the following modifications:

JavaScript:

$(window).scroll(function(e){ 
    var element = $('#callback'); 
    if ($(this).scrollTop() > 200){ 
        $('#callback').css({'top': '75px'}); /* Assuming 75 is the height of your navbar. */
    }
    if ($(this).scrollTop() < 200){
        $('#callback').css({'top': '0px'}); 
    }
});
