The flex-wrap property is a sub-property of the Flexible Box Layout module.

It defines whether the flex items are forced in a single line or can be flowed into multiple lines. If set to multiple lines, it also defines the cross-axis which determines the direction new lines are stacked in.

Reminder: the cross axis is the axis perpendicular to the main axis. Its direction depends on the main axis direction.

The flex-wrap property accepts 3 different values:

  • nowrap (default): single-line which may cause the container to overflow
  • wrap: multi-lines, direction is defined by flex-direction
  • wrap-reverse: multi-lines, opposite to direction defined by flex-direction


flex-wrap: nowrap | wrap | wrap-reverse

.flex-container {
  flex-wrap: wrap;


In the following demo:

  • The red list is set to nowrap
  • The yellow list is set to wrap
  • The blue list is set to wrap-reverse

Note: the flex-direction is set to the default value: row.

    Thank you!

    In the example, could you give each .flex-container a border so it’s readily apparent to newbs like me? Just by looking I thought the iframe is the container.

    I’ve been experimenting with flex-wrap recently, and found that Safari doesn’t support it (on desktop or mobile), although it claims to, ie. Modernizr.flexwrap is true. I’ve filed a bug report with Modernizr for this. Wanted to spread the word, since there seems to be some confusion around this property flying around in the wake of Firefox previously not having supported it.

    I left the same comment here by the way.

      It’s Safari 6 (on iOS for sure, maybe Desktop too?) where it starts supporting flex-wrap. Which is tough, because Safari 5 did support flex in general. I recently had to support to a UA sniff and float things instead if it detected Safari 5.

    Hi there,
    Been playing with flexbox a little lately.
    Still not seeing the same level of support of the flex-wrap property on mobile as there is on desktop.

    Modern Desktop browsers nicely wrap flexed width/height items using min width and height. However, modern mobile browsers appear to require more explicit dimensions in order to get the wrapping working.

    Would really appreciate some more info on this.
    I can’t seem to find any working ipad examples, or much info that explains this difference.

    Ok, my bad. Using the shorthand to specify the min-width seems to resolve my mobile wrapping woes.

    So instead of..

    flex: 1;
    min-width: 250px;

    You should use
    flex: 1 0 250px;

    Feeling better now :)
