css3 box-sizing property syntax
Function: Allows you to define specific content adapted to a certain area in an exact way.
Note: Internet Explorer, Chrome, Safari and Opera support the box-sizing attribute. Firefox requires the prefix -moz-.
The box-sizing attribute in css3 allows you to define specific elements that match a certain area in a specific way. It has two values: content-box, which means that the actual width is the sum of width, border, and padding; border -box means that the actual width is equal to the width value
