我的代码中已经有粘性标头。我正在尝试在左侧添加一个粘性 div。最初看起来不错。当我尝试滚动内容时，布局正在改变。此外，在最小尺寸（移动尺寸）时，左侧 div 未正确对齐。请建议。
var onResize = function() {
$("body").css("padding-top", $(".navbar-fixed-top").height());
};
$(window).resize(onResize);
$(function() {
onResize();
});
$(document).ready(function () {
$('body').scrollspy({
target: '#mainNavbar',
offset: 10
});
});
html, body {
height: 100%;
}
body {
padding-top: 50px;
}
.navbar-nav {
float: left;
margin: 0;
}
.navbar-nav>li {
float: left;
}
.navbar-nav>li>a {
padding-top: 15px;
padding-bottom: 15px;
}
.navbar-offset {
top: 0px;
}
.container {
background: #ccc;
}
.affix {
top: 20;
}

当你的左侧边栏出现时position: fixed它被从页面的流程中取出，这意味着主要内容移至其位置。
解决此问题的一种方法是在滚动时向主要内容添加边距。边距应等于侧边栏占用的空间量 (33.333%)。
您还没有用 jQuery 标记您的问题，但如果您对此持开放态度，这里是一种可能的方法。您可能需要使用媒体查询来调整数字。
var onResize = function() {
$("body").css("padding-top", $(".navbar-fixed-top").height());
};
$(window).resize(onResize);
$(function() {
onResize();
});
$(document).ready(function() {
$('body').scrollspy({
target: '#mainNavbar',
offset: 10
});
});
$(window).scroll(function() {
var scroll = $(window).scrollTop();
if (scroll > 0) {
$("#content").addClass("fix");
} else {
$("#content").removeClass("fix");
}
});
