Padding va borderning CSS-da elementlarni kengaytirishga ta'siri

Agar blokda padding va border bo'lsa, ular birgalikda blokni kengaytiradi:

<div id="elem"></div>

#elem1 {
	width: 100px;
	height: 100px;
	background: #f1f1f1;
	margin-bottom: 20px;
}

#elem2 {
	width: 100px;
	height: 100px;
	background: #f1f1f1;
	padding: 25px; /* padding beramiz */
	border: 10px solid green;  /* border beramiz */
}
