How to reset div to be in center after changing its position

I am working on the below code. Why am I not able to reset the .container to be center on

$("#back").on("click", function(){
      $(".container").animate({
              'margin-left': 'auto',
              'margin-right': 'auto',
              'margin':'0 auto'
        }, 550);
});


$("#move").on("click", function() {
  $(".container").animate({
    'margin-left': '2.1%'
  }, 550);
});

$("#back").on("click", function() {
  $(".container").animate({
    'margin-left': 'auto',
    'margin-right': 'auto',
    'margin': '0 auto'
  }, 550);
});
.container {
  height: 100px;
  background: khaki;
}

You can make the JavaScript remember the margin-left value, when the document gets ready to be spawned!

var margin;

$(document).ready(function() {
  $('.container').css('margin-left', 'auto'); // first, align it in the center
  margin = $('.container').css('margin-left'); // and then, store the value
  // console.log(margin);
});

$("#move").on("click", function() {
  $(".container").animate({
    'margin-left': '2.1%'
  }, 550);
});

$("#back").on("click", function() {
  $(".container").animate({
    'margin-left': margin, // use it anywhere ;)
    'margin-right': 'auto',
    'margin': '0 auto'
  }, 550);
});
.container {
  height: 100px;
  background: khaki;
}
