Unable to get resizeable to work using body tag with id

Unable to get resizeable to work using body tag with id

Hello,

Im trying to prevent a user from shrinking a screen past a certain point.

Im using the resizeable with a body selector. Ive assigned an id="body" to the body tag. But I cant get it to work. 

$(document).ready(function() { 
  $( "#body" ).resizable({            
      minWidth:  1000,
      minHeight: 600                   
    });                                
...
