Flex container width when flex is installed on the column wrap

I have a container with a fixed height and display: flex. I want the children to fit in the column first by setting -webkit-flex-flow: column wrap;.

http://jsfiddle.net/wNtqF/1/

  • Can someone explain to me how chrome calculates the resulting width of a div container (div with a green border) and why it leaves so much free space to the right of each red element. I want the container to have a width to fit all children, with no extra empty space.

  • If this is not possible with pure css, can you provide me an alternative for this?

I am using chrome v 29.0.1547.76

Code to play:

<!DOCTYPE html>
<html>
<head>
    <style>
    .flex-container {
        position: fixed;
        height: 90%;

        padding: 0;
        margin: 0;
        list-style: none;
        border: 6px solid green;

        display: -webkit-box;
        display: -moz-box;
        display: -ms-flexbox;
        display: -webkit-flex;
        display: flex;

        -webkit-flex-flow: column wrap;
        justify-content: flex-start
        align-content: flex-start;
        align-items: flex-start
    }


    /** Just to show the elements */
    body {
        margin: 0;
        padding: 0;

    .flex-item {
        background: tomato;
        padding: 5px;
        width: 100px;
        height: 100px;
        margin-top: 10px;

        line-height: 150px;
        color: white;
        font-weight: bold;
        font-size: 3em;
        text-align: center;
