Yep everything in css starts from top and goes clockwise. Check this examples:

div{
border: 1px 2px 3px 4px /* (1px top,   2px right,   3px bottom ,   4px left) */
}

div{
border:1px 2px /*(1px top and bottom,   2px left and right)*/
}

div{
border:1px 2px 3px /*(1px top,  2px right and left,  3px bottom)*/
}

div{
border:1px /*(all borders 1px)*/
}
