Scrollbar without fixed height/Dynamic height with scrollbar

问题

I have this HTML structure:

<div id="body">
    <div id="head">
        <p>Dynamic height without scrollbar</p>
    </div>
    <div id="content">
        <p>Dynamic height with scrollbar</p>
    </div>
    <div id="foot">
        <p>Fixed height without scrollbar</p>
    </div>  
</div>

I want to have the three parts inside the main part (#body) without overflow. So I need a scroll bar in the middle part.

I tried this CSS:

#content{
    border: red solid 1px;
    overflow-y: auto;
}

And this:

#content{
    border: red solid 1px;
    overflow-y: auto;
    height: 100%;
}

But neither of them work.

I made an example at JSFiddle.

Can I do this with only CSS and HTML? I'd prefer to avoid Javascript.

回答1:

Flexbox is a modern alternative that lets you do this without fixed heights or JavaScript.

Setting display: flex; flex-direction: column; on the container and flex-shrink: 0; on the header and footer divs does the trick:

HTML:

<div id="body">
    <div id="head">
        <p>Dynamic size without scrollbar</p>
        <p>Dynamic size without scrollbar</p>
        <p>Dynamic size without scrollbar</p>  
    </div>
    <div id="content">
        <p>Dynamic size with scrollbar</p>
        <p>Dynamic size with scrollbar</p>
        <p>Dynamic size with scrollbar</p>
        <p>Dynamic size with scrollbar</p>
        <p>Dynamic size with scrollbar</p>
        <p>Dynamic size with scrollbar</p>
        <p>Dynamic size with scrollbar</p>
        <p>Dynamic size with scrollbar</p>
        <p>Dynamic size with scrollbar</p>
        <p>Dynamic size with scrollbar</p>
        <p>Dynamic size with scrollbar</p>
        <p>Dynamic size with scrollbar</p>
        <p>Dynamic size with scrollbar</p>
        <p>Dynamic size with scrollbar</p>
        <p>Dynamic size with scrollbar</p>
        <p>Dynamic size with scrollbar</p>
        <p>Dynamic size with scrollbar</p>
        <p>Dynamic size with scrollbar</p>
        <p>Dynamic size with scrollbar</p>
        <p>Dynamic size with scrollbar</p>
        <p>Dynamic size with scrollbar</p>
        <p>Dynamic size with scrollbar</p>
        <p>Dynamic size with scrollbar</p>
    </div>
    <div id="foot">
        <p>Fixed size without scrollbar</p>
        <p>Fixed size without scrollbar</p>

CSS:

#body {
    position: absolute;
    top; 150px;
    left: 150px;
    height: 300px;
    width: 500px;
    border: black dashed 2px;
    display: flex;
    flex-direction: column;
}

#head {
    border: green solid 1px;
    flex-shrink: 0;
}

#content{
    border: red solid 1px;
    overflow-y: auto;
    /*height: 100%;*/
}

#foot {
    border: blue solid 1px;
    height: 50px;
    flex-shrink: 0;
}
    </div>  
</div>

回答2:

Use this:

style="max-height: 300px; overflow: auto;"

Tto avoid a fixed heigh

回答3:

You will have to specify a fixed height, you cannot use 100% because there is nothing for this to be compared to, as in height=100% of what?

回答4:

 <div id="scroll">
    <p>Try to add more text</p>
 </div>

here's the css code

#scroll {
   overflow-y:auto;
   height:auto;
   max-height:200px;
   border:1px solid black;
   width:300px;
 }

here's the demo JSFIDDLE

The JS answer to this question is:

or something similar

回答7:

A quick, clean approach using very little JS and CSS padding: http://jsfiddle.net/benjamincharity/ZcTsT/14/

var headerHeight = $('#header').height(),
    footerHeight = $('#footer').height();

$('#content').css({
  'padding-top': headerHeight,
  'padding-bottom': footerHeight
});

回答8:

Use this:

#head {
    border: green solid 1px;
    height:auto;
}    
#content{
            border: red solid 1px;
            overflow-y: scroll;
            height:150px;       
        }

回答9:

With display grid you can dynamically adjust height of each section.

#body{
  display:grid;
  grid-template-rows:1fr 1fr 1fr;
}

Add the above code and you will get desired results.

Sometimes when many levels of grids are involved css wont restrict your #content to 1fr. In such scenarios use:

#content{
  max-height:100%;
}

回答10:

I don't know if I got it right, but does this solve your problem?

I just changed the overflow-y: scroll;

#content{
    border: red solid 1px;
    overflow-y: scroll;
    height: 100px;
}

Edited

Then try to use percentage values like this: http://jsfiddle.net/6WAnd/19/

CSS markup:

#body {
    position: absolute;
    top; 150px;
    left: 150px;
    height: 98%;
    width: 500px;
    border: black dashed 2px;
}    
#head {
    border: green solid 1px;
    height: 15%;
}
#content{
    border: red solid 1px;
    overflow-y: scroll;
    height: 70%;
}
#foot {
    border: blue solid 1px;
    height: 15%;
}
