jQuery UI Dialog width Option

Last Updated : 18 Jan, 2021

Dialog width option is used to set the width of the dialog box in pixels. By default, the value is 300.

Syntax:

$( ".selector" ).dialog({
  width : 120
});

Approach: First, add jQuery UI scripts needed for your project.

<link href=”https://code.jquery.com/ui/1.10.4/themes/ui-lightness/jquery-ui.css”>
<script src=”https://code.jquery.com/jquery-1.10.2.js”></script>
<script src=”https://code.jquery.com/ui/1.10.4/jquery-ui.js”></script>

Example 1:

HTML

<!doctype html> 
<html> 
<head> 
  <link href= 
"https://code.jquery.com/ui/1.10.4/themes/ui-lightness/jquery-ui.css" 
        rel="stylesheet"> 
  <script src= 
"https://code.jquery.com/jquery-1.10.2.js"> 
  </script> 
  <script src= 
"https://code.jquery.com/ui/1.10.4/jquery-ui.js"> 
  </script> 
  <script> 
    $(function () { 
      $("#gfg").dialog({ 
        autoOpen: false, 
        width: 100 
      }); 
      $("#geeks").click(function () { 
        $("#gfg").dialog("open"); 
      }); 
    }); 
  </script> 
</head> 
<body> 
  <div id="gfg"> 
    Jquery UI| width dialog option 
  </div> 
  <button id="geeks">Open Dialog</button> 
</body> 
</html>
