Probably a stupid question, but I've seen on myspace layouts things like table table {declarations} table table table {dec's} table table table table {dec's} table, tr, td {dec's} I assume the 4 table declarations are for tables nested 4 deep? I've lightly googled this, but haven't seen an explanation. Is this correct formatting? Why do some lines have commas and others not? Are they classes? If so, why don't they start with a period? Just curious.
table, tr, td {dec's} means that all tables, tr's and td's will have those styles applied... it's just shortform instead of writing table { dec's } tr { dec's } td { dec's } where they all have the same dec's.. and i believe you're right.. when there are no commas the styles apply to the nested element.. i.e. table table { dec's } apply to a second level table but not the first check out http://www.cssbasics.com/
