左侧div在引导程序中未正确对齐

标签： html css twitter-bootstrap

我的代码中已经有了粘贴标题。我试图在左侧增加一个粘性div。最初看起来很好。当我尝试滚动内容时，布局正在发生变化。此外，在最小尺寸（移动尺寸）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
  });
});
＆＃13; 
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，它将从页面流中取出，这意味着主要内容会移动以取代它。

解决此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％）。

你没有用jQuery标记你的问题，但是如果你对它开放，这是一种可能的方法。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%;
}
