Hi,

i have this liltte function :

function Button3_onclick() 

{ 

 if (j > 5)  { 

 changebackground();   j = 1; 

 } 

 else {

 j += 1;  movebackgAround();

 }  

}

movebackground affect the background-position property and changebackground do other animations stuff .

now how to execute this code forever but without blocking the browser, i have tried with a callback but it block and freeze

thanks and good day .
