html - How come padding is not calculated into the width for submit buttons? -

first of all, think absolutely ridiculous padding considered part of width of dom element.

however, gritted teeth , accepted fact... find out submit buttons paddings not calculated part of width.

http://jsfiddle.net/cpryb/2/

how go fixing this?

i'm not sure if misspoke, padding not considered part of width default. say, if element has width of 100px, padding of 10px, , border of 5px, rendered on 100+(10*2)+(5*2)=130px. however, element contain 100px of space, amount set in width.

that beingness said, can alter default behavior box-sizing property. set border-box subtract padding (and border) box's width, or content-box render padding outside of specified width. here's a demo.

for increased compatibility should include vendor prefixes. so,

input[type=button] { -webkit-box-sizing:content-box; -moz-box-sizing:content-box; box-sizing:content-box; }

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...
