Question

我想要一个粘性页脚。我能做到这一点。但是我的菜单不再正常工作了。当我删除身体css中的position: relative时。我得到了粘性页脚。但是菜单上的身体没有向右移动。当我保留身体的position: relative时，它会随菜单向右移动。但它并没有坚持到底。

var main = function() {
  /* Push the body and the nav over by 285px over */
  $('.icon-menu').click(function() {
    $('.menu').animate({
      left: "0px"
    }, 200);

    $('body').animate({
      left: "285px"
    }, 200);
  });

  /* Then push them back */
  $('.icon-close').click(function() {
    $('.menu').animate({
      left: "-285px"
    }, 200);

    $('body').animate({
      left: "0px"
    }, 200);
  });
};


$(document).ready(main);

/* Initial body */
body {
  left: 0;
  margin: 0;
  overflow: hidden;
  position: relative;
}

/* Initial menu */
.menu {
  background: #202024 url('http://s3.amazonaws.com/codecademy-content/courses/ltp2/img/uber/black-thread.png') repeat left top;

Answer 1

.body {
position: absolute;
bottom: 0;
}

当您移除相对位置时，它会获得静态定位，静态元素不具有左侧，顶部，右侧，底部属性。

另一种方法是删除相对位置，并替换

$('body').animate({
  left: "285px"
}, 200);

要

$('body').animate({
  marginLeft: "285px"
}, 200);
