(complicated and should probably be separated on a couple of pages, so take it with a grain of salt!)
bold
italic
span.x
following: div>p>b, div>p>i, div>p>.x
spaces between simple selectors separated with comment or the universal * between two simple selectors
works in all browsers as expected (text is green)
div/**/ b space after comment!
div * i spaces around *
div * .x spaces around *, *.x would mean somthing different anyway
No spaces if selectors separated by comment or universal * preceding/following
Works (FALSELY!) in IE (at least until 7) and Safari( tested in v3.04) only (text is RED!), Firefox and Opera parse this according to the spec which says the space MUST be present!
div/**/b div and b only separated by comment but IE treats it as SPACE
div*i no spaces around * but IE treats "*" as SPACE
div* .x no space before *
Spec compliant browsers see the following:
div .a)
