html - 仅滚动内容 div，其他应固定

Question

我有三个div。我需要修复 header 和 left_side div 并滚动内容 div。我一直在寻找解决方案，发现有溢出和位置的东西。但我不能正确使用它。我怎样才能做到这一点？我会感谢各种答案。

body {   
    width: 100%;
    height: auto;
    padding: 0;
    margin: 0px auto;
    font-family: Calibri, Georgia, Ubuntu-C;  
    font-size: 16px;
    margin-bottom: 20PX
}

#header{
    width: 100%;
    height: 139px;
    background-image: url('images/Header_grey.gif');   
}


#left_side {
    width: 210px;
    height: 700px;
    background-image: url('images/Left_side.gif');
    background-repeat:repeat-y;
    overflow:hidden; 
    position:absolute;
    font-size: 16px;
}

#content {
     height: auto;
     padding: 20px;
     margin-left: 230px;
     margin-right: 20px;
    padding-bottom: 30px
}

<div id="header">
</div>

<div id="left_side">    
</div>

<div id="content">
</div>

overflow: auto;在需要时添加滚动

#header{
    width: 100%;
    height: 139px;
    background-image: url('images/Header_grey.gif');   
    overflow: hidden;  /* code added to prevent scroll */
}
    
    
#left_side{
    width: 210px;
    height: 700px;
    background-image: url('images/Left_side.gif');
    background-repeat:repeat-y;
    overflow:hidden;  /* code added to prevent scroll */
    position:absolute;
    font-size: 16px;
}
#content{
    height: auto;
    padding: 20px;
    margin-left: 230px;
    margin-right: 20px;
    padding-bottom: 30px;
    overflow: auto;  /* code added */
}

首先，您需要为内容区域设置一个固定的高度。
然后在overflow:auto那里

您的代码中的错误:: 您想要一个 div 的滚动条，但您将 div 高度声明为auto

当高度为自动时，您不能要求滚动条，要拥有滚动条，您需要为该 div 设置固定高度，并且当内容高度大于 div 高度时，它将自动引入滚动条

注意：因此您的 css 中的更改将是

#content{
    height: 300px;/*..very important if you want scroll bar...*/
    overflow: auto; /*..will introduce scroll bar when needed..*/
    padding: 20px;
    margin-left: 230px;
    margin-right: 20px;
    padding-bottom: 30px
}

您可以只使用固定位置。http://jsfiddle.net/Nrs2u/1/

#header {
    position: fixed;
    z-index: 2;
    left: 0%;
    top: 0%;
    width: 100%;
    height: 10%;
    background-color: purple;
}
#side {
    position: fixed;
    z-index: 2;
    left: 0%;
    top: 10%;
    width: 10%;
    height: 90%;
    background-color: red;
}
#body {
    position: absolute;
    left: 10%;
    top: 10%;
    width: 90%;
    height: 300%;
    background-color: orange;
}

如果您希望标题和左侧在滚动时保持在其位置，则必须使用position:fixed

position: sticky在元素上，滚动时应该保持原位，在类似的情况下对我有用。 https://www.w3schools.com/css/tryit.asp?filename=trycss_position_sticky

position: sticky;
top: 0px;

#left_side{
    ...
    overflow:auto;  

}

还设置 apadding-right以在 div 的内部内容和滚动条之间创建一个空间

作为学习练习，我决定使用 CSS3 Flexbox 更新答案。我还尝试更紧密地匹配 jstorm31 试图创建的布局。

Ritabrata 的回答是正确的：如果您希望特定元素具有滚动条，则需要将其高度（和/或宽度）设置为固定大小并将溢出设置为自动。

代码也可以在这里找到：Plunker

样式.css

#header{
    overflow: hidden; 
    background-color: #880016; 
    height: 50px;
    border-bottom: 4px solid black;
    padding: 10px;
    font-size: 20px;
}
#side_and_content {
    display: flex;
}
#left_side{
    flex: 1;
    overflow:hidden; 
    background-color: #ED1B24;  
    height: 200px;
    border-right: 2px solid black;
    padding: 10px;
}
#content{
    flex: 5;
    overflow: auto;
    background-color: #FF7F26;   
    height: 200px;
    border-left: 2px solid black;
    padding: 10px;
}

<div id="header">
    header header header header header header
</div>
<div id="side_and_content">
    <div id="left_side">  
        left side left side left side left side left side
    </div>

    <div id="content">
CSS3 Flexbox Concepts: 
Flexbox consists of flex containers and flex items.
A flex container is declared by setting the display property of an element to either flex
 (rendered as a block) or inline-flex (rendered as inline).
Inside a flex container there is one or more flex items.
Note: Everything outside a flex container and inside a flex item is rendered as usual.
Flexbox defines how flex items are laid out inside a flex container.
Flex items are positioned inside a flex container along a flex line.
 By default there is only one flex line per flex container.<br>
 It is also possible to change the direction of the flex line.
If we set the direction property to rtl (right-to-left), the text is drawn right to left, and also the flex line changes direction, which will change the page layout
