Scrolling a flexbox with overflowing content

强颜欢笑 提交于 2019-11-26 21:08:45

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 1</div>
        <div class="column">Column 1</div>
    </div>
</div>

CSS:

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

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

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.

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.

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.

Good Luck...

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).
