Button Colors

[liunx]

Hi all,
OK having experimented with changing the colors of buttons, how do i change the colors of all the borders and so on associated with them?
Can I change the border type, like a table?button{
background-color: #fff;
color: #000;
}
button.solid_black{
border: #000 1px solid;
}
button.dotted_green{
border: #0f0 1px dotted;
}
button.dashed_grey{
border: #777 1px dashed;
}
