Hi, the box-sizing property alters the way the browser calculates the total width and height of an element. By default, when you set any padding/border values on an element after defining a specific width, the total width of that element would expand, making it bigger than what you may prefer.

So the value border-box alters that, and any borders/padding values get added up inside of the element's width instead of expanding it.

It's usually good practice to add box-sizing: border-box to the universal selector (*) when starting your CSS file so its out of the way and all elements get that.

The value inherit what you see here basically tells the element to inherit the value for the border-box property (border-box) from the above parent.

You will come across sites that will use the html tag in css and apply the border-box property within that selector, then use the universal selector to inherit that value.
