Question

想听大家的说法，不要copy了。

Answer 1

Only the flex syntax specification has been updated in several versions:

• The former display:box is the 2009 syntax version. You need to add the browser prefix when using it, but it is now outdated.

• The latter display:flex is the latest revised grammar version in 2012, which has better browser support and will become the standard grammar in the future.

• In 2011, a strange syntax version display:flexbox was also proposed. It was unofficial and was mainly used by IE browser at that time.

display:boxBrowser support:

IE	Firefox	Chrome	Safari	Opera
不支持	2.0-40.0 （-moz-）	4.0-45.0 （-webkit-）	6.0-8.0 （-webkit-）	15.0-29.0 （-webkit-）

display:flexBrowser support:

IE	Firefox	Chrome	Safari	Opera
11.0+	22.0+	21.0+（-webkit-） 29.0+	6.1+（-webkit-） 9.0+	15.0+（-webkit-） 17.0+

The more complete compatibility code is as follows:

.box {
    display: -webkit-box; /* Chrome 4+, Safari 3.1, iOS Safari 3.2+ */
    display: -moz-box; /* Firefox 17- */
    display: -webkit-flex; /* Chrome 21+, Safari 6.1+, iOS Safari 7+, Opera 15/16 */
    display: -moz-flex; /* Firefox 18+ */
    display: -ms-flexbox; /* IE 10 */
    display: flex; /* Chrome 29+, Firefox 22+, IE 11+, Opera 12.1/17/18, Android 4.4+ */
}
