Content Choreography

This is a slimed down example of the great work done by Jordan Moore. The basic proof of concept is, how can we manage content placement depending on user experience?

See example http://box-ordinal.herokuapp.com/

What does it do?

What was pretty awesome about Jordan's example was how the elements reordered depending on the user's device experience. Nice. Reading up on the techniques used in W3Schools I recreated the example in a much simpler light.

Progressive enhancement meets adaptive design

The key feature that makes this work is a combination of flexbox and box-ordinal-group. Where we get progressive, all browsers that support these featured also support @media queries.

For basic layout I am using standard block elements and floats. To add this spice of awesome, using the @media query we are then removing the float, adding the flex and assigning layout order.

Example code

// all browsers understand these base styles
section {
  max-width: 60em;
  margin: 0 auto;

//browsers that support @media get this dash of awesome
@media screen and (max-width: 1024px) {

  // assign the flexbox attributes to the parent container
  section {

  // set the placement of the content box
  article {
    box-ordinal-group: 2;
    -moz-box-ordinal-group: 2;
    -webkit-box-ordinal-group: 2;

    // remove float and set width
    float: none;
    width: auto;

Key points to consider

  • All block elements that float only float above the @media breakpoint
  • It is only below the @media breakpoint that all floats are set to none, widths set to auto and the parent block is instructed to use flexbox.
