Your user or web application may require that all animations are disabled, but the effect of revealing information or scrolling (or whichever animation type) may still be required. jQuery has a way to disable all animations from one access point but still supports the animate method and its final value.

$.fx.off = true; 
$(document).ready(function () { 
   $('#animate').click(function () { 
     $('.box').animate({ width: '+=100', height: '+=100' }); 
     }); 
   }); 

By setting fx to off using the following line, all animation calls have the same effect as calling css() directly:

$.fx.off = true; 

This can be set at any point and it will disable the animations, which means it can be offered as a user preference. To enable animations again

$.fx.off = false;
