Does "width" overwrite "padding"?

Let's say the width of the containing box is 5cm, padding(all sides) is 2cm.

if I set the width of the content to be 50%. Now the absolute value of the width would be 2.5 cm. But if the padding effect is still there, then the box now would be 2+2.5+2 = 6.5cm. But the content would no longer be 50% of width now(2.5/6.5 != 50%).

I'm kinda confused,any help? Thanks!

The size of the container change it's width if you add padding or borders. For Example: If you have a container with 150 px and you add 1px border and 15px padding the width will be 182 (150+1+1+15+15). If you don't want it to change the size use:

box-sizing: border-box;

Don't forget to use the prefix to support different browsers
