将动画块滑动到另一个动画块，并在结尾处反弹

Question

我正在尝试重现这种效果：Design URL

我制作了CSS和少量的JavaScript，但是我不知道如何使白色块向左/向右滑动并在末尾进行一些棘手的跳转，然后以很少的淡入显示文本（这部分，我想我很容易找到它。）

到目前为止，这是我的CSS和JS：

// Login button comportment -> to Register
  $('.login-box-texts .btn').on('click', function (e) {
    e.preventDefault();
    $('.login-box').addClass('is-hidden');
    $('.login-box-texts').addClass('is-hidden');
    $('.register-box').removeClass('is-hidden');
    $('.register-box-texts').removeClass('is-hidden');
  });

  // Register button comportment -> to Login
  $('.register-box-texts .btn').on('click', function (e) {
    e.preventDefault();
    $('.register-box').addClass('is-hidden');
    $('.register-box-texts').addClass('is-hidden');
    $('.login-box').removeClass('is-hidden');
    $('.login-box-texts').removeClass('is-hidden');
  });

.btn {
  position: relative;
  display: inline-block;
  padding: 18px 30px;
  border-top-left-radius: 50px;
  border-top-right-radius: 50px;

}

.btn::before {
  content: '';
  position: absolute;
  top: -3px;

我看到当与三次贝塞尔曲线之类的div相同的div时如何使它“跳动”，但是在这里我不知道，也许我必须适应我的HTML结构吗？我不知道。

感谢您的帮助。

编辑：我找到了一种使其滑动并变得出色的方法。但是我找不到一种像我给您的URL那样平滑的方法，如果您可以帮助我，那真的很棒^^

这是代码：

// Login button comportment -> to Register
$('.login-box-texts .btn').on('click', function(e) {
  e.preventDefault();

  $('.register-box').removeAttr('style');
  $('.login-register-box-container').css({
    'margin-left': 20,
    'margin-right': 45
  });

  $('.login-box').css('left', 'inherit');
  $('.login-box-texts').addClass('is-hidden');
  $('.login-box').animate({
    'right': 0
  }, {
    complete: function() {
      $('.login-box').addClass('is-hidden');
      $('.register-box').removeClass('is-hidden');
      $('.register-box-texts').removeClass('is-hidden');
    }
  });
});

// Register button comportment -> to Login
$('.register-box-texts .btn').on('click', function(e) {
  e.preventDefault();

  $('.login-box').removeAttr('style');
  $('.login-register-box-container').css({

  });

  }, {

如您所见，我找到了一种制作滑块的方法。现在，我认为这只是动画，但我真的看不到如何避免显示与URL中显示的内容类似的东西：/

谢谢
