CSS Properties

This appendix provides a laundry list of sorts of
CSS properties with which you may need to be familiar at
some point.
Browser Support
Historically, CSS support in browsers has been erratic. To help
developers and browser implementors navigate these
troubled waters, the W3C has issued a CSS 2.1 specification
that reflects a survey of modern browsers; this appendix is
drawn from that specification.
For additional information about property support, go to
www.blooberry.com; it’s a valuable resource. Brian
Wilson has posted the results of his extensive testing of some
of the major browsers (Internet Explorer, Netscape, and
Opera).
For many properties, it is sufficient to determine whether they
are supported by your target browsers, but, particularly for
the positioning properties, testing on as many browsers as
reasonable is highly recommended. You have at least four
modern rendering engines to consider:
✦ Internet Explorer for Windows
✦ Gecko (as seen in Mozilla, Netscape 6/7, and several
other browsers)
✦ Konqueror (the browser re-used by Apple as Safari)
✦ Opera
Note Internet Explorer 5.2 for the Macintosh is apparently different
(and significantly more standards-compliant) from
the then-current Windows versions, but has been abandoned
by Microsoft and supplanted by Safari.
