我的代码中已经有粘性 header 。我正在尝试在左侧添加一个粘性 div。最初它看起来很好。当我尝试滚动内容时，布局正在改变。同样在最小尺寸(移动尺寸)下，左侧 div 未正确对齐。请提出建议。
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;

当您的左侧边栏获得 position: fixed 时，它会脱离页面流，这意味着主要内容会移到它的位置。
解决这个问题的方法是在滚动时为主要内容添加边距。边距应等于侧边栏占用的空间量 (33.333%)。
您尚未使用 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");
}
});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;
}
#content.fix {
margin-left: 33.333333%;
