無論如何，我的側邊欄都是固定的。如何使用側邊欄滾動？

Question

我的側邊欄有點動態：我發表的文章越多，獲得的內容就越大。 但是，側邊欄也已固定，這使得有時無法看到其底部（當我減小瀏覽器窗口或有很多文章時）。 如何使通過側欄滾動成為可能？ 這是我的CSS文件，側邊欄主要由div代表，類為“ container2”

@import "bootstrap-sprockets";
@import "bootstrap";
/* mixins, variables */
 /* universal */
 html {
 overflow-y: scroll;
 }
 body {
 padding-top: 60px;
 position: relative;
 }
 section {
 overflow: auto;
 }
textarea {
resize: vertical;
}
.center {
text-align: center;
h1 {
margin-bottom: 10px;
}
}
/* typography */
h1, h2, h3, h4, h5, h6 {
line-height: 1;
}
h1 {
font-size: 3em;
letter-spacing: -2px;
margin-bottom: 30px;
text-align: center;
}
h2 {
font-size: 1.2em;
letter-spacing: -1px;
margin-bottom: 30px;
text-align: center;
font-weight: normal;
color: #3BB9FF;
}
p {
font-size: 1.1em;
line-height: 1.7em;
}
/* 
footer{
background-color: #222;
div ul li{
display:block;
vertical-align: top;
width: 50%;
float: left;
}
}
*/
@mixin box_sizing {
-moz-box-sizing:    border-box;
-webkit-box-sizing: border-box;
box-sizing:         border-box;
}
/* miscellaneous */
.debug_dump {
clear: both;
float: left;
width: 100%;
margin-top: 45px;
@include box_sizing;
}
/* forms */
input, textarea, select, .uneditable-input {
border: 1px solid #bbb;
width: 100%;
margin-bottom: 15px;
@include box_sizing;
}
input {
height: auto !important;
}
#error_explanation {
color: red;
ul {
color: red;
margin: 0 0 30px 0;
}
}
.field_with_errors {
@extend .has-error;
.form-control {
color: $state-danger-text;
}
}
/* articles */
.container1 {
opacity: 0.75;
border: 1px solid #000000;
border-radius: 10px;
padding: 30px 75px 75px 100px;
overflow: scroll ;
}
.container1 p img {
float: left;
margin-top: 9px;
margin-right: 15px;
margin-bottom: 15px;
}
.container2 {
position: fixed;
padding: 0px 75px 20px 100px;
clear: both;
background-color: #FFFFFF; /*#F8F8F8;*/
border-radius: 5px;
overflow: scroll;
}
footer{
clear: both ;
padding: 30px 75px 75px 100px;
}
/*Search*/
.search { 
padding:6px 15px 6px 30px;
margin:3px; 
}
.lighter, .light, .dark {
width:95%;
height:50px;
}
.rounded { 
border-radius:15px; 
-moz-border-radius:15px; 
-webkit-border-radius:15px; 
}

我的側邊欄是，這是我的app / views / layouts / application.html.erb，側邊欄由div內的內容表示：

<div class="col-md-2" id ="sidebar">
<div class="container2">

最后：app / views / layouts / application.html.erb：

<!DOCTYPE html>
<html>
<head>
<title><%= full_title(yield(:title)) %></title>

<%= csrf_meta_tags %>
<%= render 'layouts/shim' %>
</head>
<body>
<%= render 'layouts/header' %>
<div class="container">
<div class="row">
 <div class="col-md-9">
<% flash.each do |message_type, message| %>
    <div class="alert alert-<%= message_type %>"><%= message %></div>
  <% end %>
  <%= yield %>
    </div>
    <div class="col-md-2" id ="sidebar">
    <div class="container2">

         <%= form_tag articles_path, :method => :get do   %>

<% end %>   
         <!-- <form>

           </form>
           -->

如何使用側邊欄進行滾動，以便查看其所有內容？

Answer 1

您必須在邊欄上設置一個高度，然后告訴溢出的內容滾動。 這樣的事情應該起作用：

#sidebar {
    height: 600px; /* or whatever height you want */
    overflow: scroll;
}

無論如何，我的側邊欄都是固定的。如何使用側邊欄滾動？
