Very absurde css costumization

hi,
using firebug i go to change something in the css style
in this case i wanted change the .item-bobody margin from 72px 0 10px in 2px 0 10 px (riga2167)
Using filezilla i take the css style in www.mysite.it/templates/gk_technews/css/template.css
i change the value and then i upload the css style on the server but nothing changes, the value is the same 72xp

Why ? that's very strange

1. Please do not edit template core files (it's gonna hit you back during template update)
2. Please verify if less compillation is disabled in template settings.
3. Instead of template core css files, please use override.css (enable it first in template settings).

ok in this case what i should write in as costum css code?

by firebug i see that:

}
tbody tr td {
border-bottom: 1px solid #eee;
padding: 14px;
}

i need to write padding 2px

tnx for your answer

Tnx so much.. it was very easy
it was anough to put the code with the different value

Tnx so much!!!!!
