css - CSS3 box-shadow property doesn't validate? -

when run css through w3c's validator, time utilize box-shadow property, error this:

0 not box-shadow value : 0 0 10px #000

it appears stop @ whatever first value is, since changing order of values alter error match:

#000 not box-shadow value : #000 0 0 10px

i'm validating profile set css3, it's not case of me forgetting alter default profile setting css2 (where box-shadow property doesn't exist).

why doesn't think of values i'm using correct? shadow render fine in firefox , other browser supports non-prefixed box-shadow property.

it's a known validator bug. apparently forgot unitless values permitted (especially unitless 0 values). there's nil wrong css; values you're using correct.

if you're picky , can't set bug tarnishing otherwise would-have-been successful validation, can add together units 0 values:

box-shadow: 0px 0px 10px #000;

but whenever run situations this, don't bother, knowing it's harmless validator bug , not wrong css.

note of update bug has been fixed since august 30, 2012.

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
