box-sizing: border-box;

In traditional box model, the width and height of an element specifies the width that is inclusive of the border of the element. It includes the content, padding and border as shown below.
  • container has width = 250 (200 + 10 x 2 + 15 x 2) px and height = 150 (100 + 10 x 2 + 15 x 2) px;
  • content has width = 150 px and height = 50 px;
Notice, that when you use border-box in the example below, it's visually smaller than the example above. [codepen_embed height="268" theme_id="0" slug_hash="obBWeL" default_tab="result" user="kavitshah8"]See the Pen box-sizing-2 by Kavit Shah (@kavitshah8) on CodePen.[/codepen_embed]
