Question

在右下角，我有1个按钮可以打开聊天，然后是一个div，它显示当前的在线用户，然后是另一个按钮，可以到达页面顶部。

我在按钮上使用<button>标签，但按钮和div的填充不同。如果我使用相同的填充，div会更大，但不会太多，但它会让我烦恼。

有没有简单的方法来解决这个问题？它们都是position:fixed;

这是我的代码：

＆＃13;

jQuery(document).ready(function($) {
  $(window).scroll(function() {
    if ($(this).scrollTop() > 50) {
      $('#backToTop').fadeIn('slow');
    } else {
      $('#backToTop').fadeOut('slow');
    }
  });
  $('#backToTop').click(function() {
    $("html, body").animate({
      scrollTop: 0
    }, 500);
    //$("html, body").scrollTop(0); //For without animation
    return false;
  });
});
