Definition and usage

The box-sizing attribute allows you to define specific elements that match a region in a specific way.

For example, if you want to place two boxes with borders side by side, you can set box-sizing to "border-box ". This allows the browser to display a box with a specified width and height, and put the border and padding into the box.
