display : flex, box, flexbox?
Many of us are aware today that the older values of the display property like inline and block are outdated after the new flexible box model has been introduced in CSS3. But, we might find different information on the web in the same flexible box model.
We might find mainly 3 different values of the display property namely flex , box and flexbox . What is the difference between these three flexible box models and which one to use?
You use whichever ones you need for the browsers you need to support.
display: box
As far as I can tell, wrapping via box-lines: multiple is not implemented in any browser.
display: flexbox
display: flex - the current standard
http://caniuse.com/#feat=flexbox (Note that IE10 is the only browser marked as having partial support that supports wrapping)
The specs for flexbox and flex are similar enough there's no reason not to include both, especially since IE10 only supports the flexbox spec. The spec for box is very different and might not be worth including depending on the effect you're after, even though nearly all properties have an analog to the ones found in the flexbox / flex specs.
You may find that there are some browsers that support multiple specs. There will likely come a time where they will drop support for the older spec, so always make sure you include the flex properties.
As far as I know, the above three different versions of the flexible box model can be classified by their ages.
display: box - This was the first flexible box model that was accepted as the newest model around the year 2009. Don't use it.
display: flexbox - This flexible box model came in the year 2011 which was still in its development. Don't use it.
display: flex - This is the newest flexible box model that currently finds its place as the latest box standard. This might further undergo some changes but this is preferred to the other two standards.
