css - Div spacing problem -


i trying space out divs. have 5 divs 30px wide , want put these div 150px wide. sounds simple find 5 divs don't fit.

5*30 = 150 (but requires 166px outer div them fit inline)

i have fiddle

<div class="a">     <div class="b" >a</div>     <div class="b" >b</div>     <div class="b" >c</div>     <div class="b" >d</div>             <div class="b" >e</div>     <div class="b" >f</div> </div>  div.a { background-color: red; width: 150px;} div.b { display: inline-block; height: 20px; width: 30px;}

is there missing? can't understand why browsers space way do.

as turning divs inline elements, other inline content come play, i.e. white space between elements. space between each div, takes few pixels more.

if remove white space between divs, there no spaces between them, , 5 elements fit in 150 pixels:

sql - text truncated using perl DBI insert -

the problem dbi 's insert leaves long string truncated when inserting ms sql server. here codes: my $insert = $dbh->prepare("insert my_table (field_1, field_2) values (?, ?)"); $insert->execute($value_1, $value_2); where field_2 has data type of varchar(100) , $value_2 text string of 90 characters spaces no other special characters. after statement executed, no error raised, checked database , apparently actual inserted $value_2 truncated @ 80th character, in middle of regular english word (i.e. not special character). i've tried alter data type of field_2 varchar(150) , text . i've used $dbh->quote($value_2) in place of $value_2 . didn't help. why happening? should do? thx!! if using freetds bug identified in freetds mailing list. see freetds silently truncating text/varchar/etc fields 80 characters , http://lists.ibiblio.org/pipermail/freetds/2011q2/026943.html , http://lists.ibiblio.org/pipermail/freetds/2011q2/026...
