If you mean changing background color of element in which you add border, just change the background of that element
div {
boder : 3px solid brown;
background: grey ;
}

/* CSS */
element{
border-color:red;
border-width:2px;
border-style:solid;
}

OR

border:2px solid red;
}

Both will give the same result

element{
background-color:red;
}

where element is an HTML element
