Scrolling a flexbox with overflowing content

CssLayoutMultiple ColumnsFlexbox

Css Problem Overview

enter image description here

Here's the code I'm using to achieve the above layout:

.header {
  height: 50px;
}

.body {
  position: absolute;
  top: 50px;
  right: 0;
  bottom: 0;
  left: 0;
  display: flex;
}

.sidebar {
  width: 140px;
}

.main {
  flex: 1;
  display: flex;
  flex-direction: column;
}

.content {
  flex: 1;
  display: flex;
}

.column {
  padding: 20px;
  border-right: 1px solid #999;
}


<div class="header">Main header</div>
<div class="body">
  <div class="sidebar">Sidebar</div>

  <div class="main">
    <div class="page-header">Page Header. Content columns are below.</div>
    <div class="content">
      <div class="column">Column 1</div>
      <div class="column">Column 1</div>
      <div class="column">Column 1</div>
    </div>
  </div>
</div>

I omitted the code used for styling. You can see all of it in the pen.

The above works, but when the content area's content overflows, it makes the whole page scroll. I only want the content area itself to scroll, so I added overflow: auto to the content div.

The problem with this now is that the columns themselves don't extend beyond their parents height, so the borders are cut off there too.

Here's the pen showing the scrolling issue.

How can I set the content area to scroll independently, while still having its children extend beyond the content box's height?

Css Solutions

Solution 1 - Css

I've spoken to Tab Atkins (author of the flexbox spec) about this, and this is what we came up with:

HTML:

<div class="content">
	<div class="box">
		<div class="column">Column 1</div>
		<div class="column">Column 2</div>
		<div class="column">Column 3</div>
	</div>
</div>

CSS:

.content {
    flex: 1;
    display: flex;
    overflow: auto;
}

.box {
    display: flex;
    min-height: min-content; /* needs vendor prefixes */
}

Here are the pens:

  1. Short columns being stretched.
  2. Longer columns overflowing and scrolling.

The reason this works is because align-items: stretch doesn't shrink its items if they have an intrinsic height, which is accomplished here by min-content.

Solution 2 - Css

I just solved this problem very elegantly after a lot of trial and error.

Check out my blog post: http://geon.github.io/programming/2016/02/24/flexbox-full-page-web-app-layout

Basically, to make a flexbox cell scrollable, you have to make all its parents overflow: hidden;, or it will just ignore your overflow settings and make the parent larger instead.

Solution 3 - Css

Working with position:absolute; along with flex:

Position the flex item with position: relative. Then inside of it, add another <div> element with:

position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;

This extends the element to the boundaries of its relative-positioned parent, but does not allow to extend it. Inside, overflow: auto; will then work as expected.

.all-0 {
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
}
p {
  text-align: justify;
}
.bottom-0 {
  bottom: 0;
}
.overflow-auto {
  overflow: auto;
}

Solution 4 - Css

A little late but this could help: http://webdesign.tutsplus.com/tutorials/how-to-make-responsive-scrollable-panels-with-flexbox--cms-23269

Basically you need to put html,body to height: 100%; and wrap all your content into a <div class="wrap"> <!-- content --> </div>

CSS:

html, body {
  height: 100%;
}
 
.wrap {
  height: 100vh;
  display: flex;
}

Solution 5 - Css

Add this:

align-items: flex-start;

to the rule for .content {}. That fixes it in your pen for me, at least (in both Firefox & Chrome).

By default, .content has align-items: stretch, which makes it size all of its auto-height children to match its own height, per http://dev.w3.org/csswg/css-flexbox/#algo-stretch. In contrast, the value flex-start lets the children compute their own heights, and align themselves at its starting edge (and overflow, and trigger a scrollbar).

Solution 6 - Css

The following CSS changes in bold (plus a bunch of content in the columns to test scrolling) will work. Well, it makes each content column individually scrollable, which may be more (better?) than originally requested. Anyway, see the result in this Pen.

> .content { flex: 1; display: flex; height: 1px; } > > .column { padding: 20px; border-right: 1px solid #999; overflow: > auto; }

The trick here seems to be that a scrollable panel needs to have a height literally set somewhere (in this case, via its parent), not just determined by flexbox. So even height: 1px works. The flex-grow:1 will still size the panel to fit properly.

Solution 7 - Css

One issue that I've come across is that to have a scrollbar a n element needs a height to be specified (and not as a %).

The trick is to nest another set of divs within each column, and set the column parent's display to flex with flex-direction: column.

<style>
    html, body {
        height: 100%;
        margin: 0;
        padding: 0;
    }

    body {
        overflow-y: hidden;
        overflow-x: hidden;
        color: white;
    }

    .base-container {
        display: flex;
        flex: 1;
        flex-direction: column;
        width: 100%;
        height: 100%;
        overflow-y: hidden;
        align-items: stretch;
    }

    .title {
        flex: 0 0 50px;
        color: black;
    }

    .container {
        flex: 1 1 auto;
        display: flex;
        flex-direction: column;
    }

        .container .header {
            flex: 0 0 50px;
            background-color: red;
        }

        .container .body {
            flex: 1 1 auto;
            display: flex;
            flex-direction: row;
        }

            .container .body .left {
                display: flex;
                flex-direction: column;
                flex: 0 0 80px;
                background-color: blue;
            }
                .container .body .left .content,
                .container .body .main .content,
                .container .body .right .content {
                    flex: 1 1 auto;
                    overflow-y: auto;
                    height: 100px;
                }
                .container .body .main .content.noscrollbar {
                    overflow-y: hidden;
                }

            .container .body .main {
                display: flex;
                flex-direction: column;
                flex: 1 1 auto;
                background-color: green;
            }

            .container .body .right {
                display: flex;
                flex-direction: column;
                flex: 0 0 300px;
                background-color: yellow;
                color: black;
            }

    .test {
        margin: 5px 5px;
        border: 1px solid white;
        height: calc(100% - 10px);
    }
</style>

And here's the html:

    <div class="title">

Solution 8 - Css

The solution for this problem is just to add overflow: auto; to the .content for making the content wrapper scrollable.

Furthermore, there are circumstances occurring along with Flexbox wrapper and overflowed scrollable content like this codepen.

The solution is to add overflow: hidden (or auto); to the parent of the wrapper (set with overflow: auto;) around large contents.

Solution 9 - Css

I didn't see this answer anywhere. But the trick I needed was to make sure the items had a flex-shrink: 0; else they'll get squeezed.

.container {
  display: flex;
  overflow: auto
}

.container > * {
  flex-shrink: 0;
  width: 10em;
  height: 10em;
  background: linear-gradient(to bottom right, #F0F, #0FF);
}


<div class="container">
  <div></div>
  <div></div>
  <div></div>
  <div></div>
  <div></div>
  <div></div>
  <div></div>
  <div></div>
  <div></div>
  <div></div>
</div>

Solution 10 - Css

.list-wrap {
  width: 355px;
  height: 100%;
  position: relative;

  .list {
    position: absolute;
    top: 0;
    bottom: 0;
    overflow-y: auto;
    width: 100%;
  }
}

Solution 11 - Css

I tried a lot of the answers above without much joy. I suspect that a lot of these answers are out of date or just didn't fit my requirements. The answer to my problem came from a related question:

> The Automatic Minimum Size of Flex Items > ---------------------------------------- > > You're encountering a flexbox default setting. > > A flex item cannot be smaller than the size of its content along the > main axis.

So the thing that was preventing my flex box item from scrolling was that the size of the element would automatically adjust to auto based on the content and then resize, not scroll. Here's a fully working modern example (using tailwind):

<!DOCTYPE html>
<html class="h-full">
    <head>
        <script src="https://cdn.tailwindcss.com"></script>
    </head>
    <body class="h-full">
        <div class="h-full flex flex-col items-stretch">
            <div class="bg-white border-b border-gray-400">
              <h1>
