    $('#start').click(function()  {         $('html,body').animate({             scrolltop : $('.scroll').offset().top         },1500);//end animate     });//end click

i used change #start , .scroll everytime. tips?

wrap in function.

function foo(startelem, scrollelem) {     $(startelem).click(function()  {         $('html,body').animate({             scrolltop : $(scrollelem).offset().top         },1500);//end animate     }); }
