Question

我的侧边栏有点动态：我发布的文章越多，它就越大。但是，侧边栏也是固定的，这使得有时无法看到它的底部（当我减少浏览器窗口或有很多文章时）。如何通过侧边栏滚动？这是我的CSS文件，侧边栏主要由div表示，其中class =＆＃34; container2＆＃34;

@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;

line-height: 1.7em;
}
/*

@mixin box_sizing {
-moz-box-sizing:    border-box;
-webkit-box-sizing: border-box;
box-sizing:         border-box;
}
/* miscellaneous */
.debug_dump {

@include box_sizing;

input, textarea, select, .uneditable-input {

}
#error_explanation {

}
}
.field_with_errors {

.form-control {

}
}
/* 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; 
}

我的侧边栏是，这里是我的app / views / layouts / application.html.erb，我的侧边栏由div内的内容表示：

<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>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>

<%= 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   %>

如何使用侧边栏滚动以便我可以看到它的所有内容？

Answer 1

您必须在侧边栏上设置高度，然后告诉溢出的内容滚动。这样的事情应该有效：

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

我的侧边栏无论如何都是固定的。如何使用侧边栏进行滚动？
