How can I change font - mailing list?

Hi,

How can I change the font size of selected boxes here and the submit button to 12px? Currently they are slightly bigger than the rest.

Also, how can I change the colour of the button to black (currently it's dark grey)?

.caption input {
   font-size: 12px !important;
}
input[type="submit"] {
   font-size: 12px !important;
   background: #333 !important;
}

Great, it worked, thanks!
