Flexbox browser compatiability
Browser support for flexbox is excellent, and the majority of browsers do not need a prefix at this point. Safari was the last of the major browsers to remove prefixes, with the release of Safari 9 in 2015. The two browsers you should still keep in mind for cross-browser compatibility are:
- Internet Explorer 10, which implemented the display: flexbox version of the specification with the -ms- prefix.
- UC Browser, which still supports the 2009 display: box version only with the -webkit- prefix.
Note also that Internet Explorer 11 supports the modern display: flex specification however it has a number of bugs in the implementation.
