Scrolling a flexbox with overflowing content


Question

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?

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.

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.

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;
}

Worked for me. Hope it helps

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).

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="base-container">
    <div class="title">
        Title
    </div>
    <div class="container">
        <div class="header">

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.
