Question

我有三个div。我需要修复标题和left_side divs以及滚动内容div。我一直在寻找解决方案，并找到了溢出和位置的东西。但我无法核心使用它。我怎样才能做到这一点？我会感谢各种答案。

  HTML

<div id="header">

</div>

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

<div id="content">
</div


CSS

body {   
    width: 100%;
    height: auto;
    padding: 0;
    margin: 0px auto;
    font-family: Calibri, Georgia, Ubuntu-C;

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

#content{
     height: auto;
     padding: 20px;
     margin-left: 230px;

    padding-bottom: 30px
 }

Answer 1

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
 }

Answer 2

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

你的代码中的错误::你想要一个div的滚动条，但你声明div高度为auto

当高度为自动时你不能要求滚动条，要有滚动条你需要为该div设置一个固定的高度，当内容高度大于div高度时它会自动引入滚动条

注意：所以css中的更改将是

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

Answer 3

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

Answer 4

你可以使用固定的位置。 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;
}

Answer 5

#left_side{
    ...
    overflow:auto;  

}

还设置padding-right以在div的内容和滚动条之间创建空格

Answer 6

作为一项学习练习，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：如果你想让一个特定元素有滚动条，你需要将它的高度（和/或宽度）设置为固定大小并溢出到自动。

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

Answer 7

position: sticky上的元素（在滚动时应保持原状）在类似情况下对我有用。 https://www.w3schools.com/css/tryit.asp?filename=trycss_position_sticky

position: sticky;
top: 0px;

仅滚动内容div，其他应该是固定的
