【问题标题】：Create a sticky header and sticky sidebar? [closed]创建一个粘性标题和粘性侧边栏？ [关闭]
【发布时间】：2018-03-23 02:54:01
【问题描述】：
我想要一个粘性标题和菜单#fixedheader 和一个粘性侧边栏#stickySocialIcons。我已经尝试过position:fixed，但问题是整个网站都受到影响...
关于粘性侧边栏，我的问题是，如果我使用position:fixed，侧边栏不会在带有背景的页脚处停止，并且当屏幕接触侧边栏时它不会开始粘在屏幕上。它总是在同一个位置...
有没有人有想法，我该如何解决？

希望您至少尝试自己编写代码。 Stack Overflow 不是代码编写服务。我建议你做一些additional research，无论是通过谷歌还是通过搜索，尝试一下。如果您仍然遇到问题，请返回您的代码并解释您尝试过的操作。

【解决方案2】：
试试这个 css 和 JQuery 以获得粘性标题
#fixedheader {
position: fixed;
width: 100%;
z-index: 9999;
background: #fff;
}
jQuery
$(document).ready(function () {
var sticky = $('#fixedheader');
var height = sticky.height();
$(document.body).css('margin-top', height + "px");
});
