Center JQuery within the current screen

Question

Center JQuery within the current screen

My implementation of Jquery dialog is as follows:

<body>
  <div id="comments_dialog">
   Insert a comment
   <form>
     <input type="text" id="search" name="q">
   </form>
  </div>
....
</body>

dialog = $( "#comment_dialog" ).dialog({
      autoOpen: false,
      height: 400,
      width: 350,
      dialogClass: "flora",
      modal: true,
      buttons: {
        "New Comment": addComment,
        Cancel: function() {
          dialog.dialog( "close" );
        }
      },
      close: function() {
        form[ 0 ].reset();
      }
    });

My webpage contains a lot of scrollable data.

The current issue I am facing is that the dialog box appears in the middle of the page, and I want it to be positioned in the center of the CURRENT screen, eliminating the need for scrolling.

Is there a way to achieve this?

UPDATE

After trying out various suggestions, I have set the CSS position to fixed like so:

.flora.ui-front {
    z-index: 1000 !important;
     position:fixed !important;
}
.flora.ui-dialog {
    z-index: 1001 !important;
     position:fixed !important;
}

However, I have learned that using a fixed position may cause conflicts with zIndex. What alternatives do I have if I still want the dialog box to appear on top and centered on the current screen?

Consider revising your CSS code by replacing position:absolute; with position:fixed;

#comment_dialog{
position:fixed;
}

My preferred method for creating modals and dialogs:

#dialog_box{
    position: fixed;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
}

If your div has a size (it doesn't have to be fixed), it will appear in the center of the window both horizontally and vertically.

To apply these styles dynamically with jQuery, use this code:

$("#dialog_box").css({
    "position" : "fixed",
    "top": "0",
    "left": "0",
    "right": "0",
    "bottom": "0"
});

To achieve a fixed position, you can utilize the calc function for defining the top and left properties.

#comment_dialog {
  position:fixed;
  left: calc(50% - 200px) !important;
  top: calc(50% - 175px) !important;
}

Hopefully, this solution proves to be beneficial for your requirements.

Check out this CSS snippet to center a dialog:

To visualize the effect, run the example in "Full Screen" mode and resize your browser window.

Here's how it works:

Apply position:fixed to the dialog element to position it relative to the browser window.
Use calc to calculate the top and left positions, ensuring the dialog is always centered on the viewport.
The top value is calculated as 50% of the viewport height minus half the dialog height.
The left value is calculated as 50% of the viewport width minus half the dialog width.
As a result, the dialog is consistently positioned at the center of the viewport.

#comments_dialog {
  position:fixed;
  top: calc(50vh - 250px/2);
  left: calc(50vw - 350px/2);
  height: 250px;
  width: 350px;
  background-color:yellow;
  z-index: 1000;
}

<div id="comments_dialog">
  Your content here.
</div>

Alternatively, achieve the same result with jQuery by adding inline styles:

$("#comments_dialog").css({
  "position": "fixed",
  "top": "calc(50vh - 250px/2)",
  "left": "calc(50vw - 350px/2)",
  "width": "350px",
  "height": "250px",
  "background-color": "yellow",
  "z-index": "1000";
});
