The Book of CSS3 - A Developer\'s Guide to the Future of Web Design (2nd edition)

258 Appendix A

Chrome and Firefox are evergreen browsers: they update automati-

cally and version numbers are only used for internal reference. Internet

Explorer and Safari continue to release versions at regular intervals; as I

write this, IE11 and Safari 8 are the most recent versions.

In the support tables below, where a Yes is used it means that the fea-

ture is supported either in an evergreen browser or in at least the last three

versions of Safari (6–8) or IE (9–11). Otherwise, a version number will be

shown. With regards to IE, it’s safe to presume that, with a very few excep-

tions, almost nothing in this book is implemented in IE8 or below.

I keep updated versions of these tables on the website that accompanies

this book (http://www.thebookofcss3.com/), so check there regularly for the

most up-to-date implementation status.
