Hi - I am following The Ultimate HTML5 & CSS3 Series: Part 2, **Chapter 3**. When I inspect the box I see the border value of **9.6** even though I set the border to the following value. Why would the browser not use the whole width? Attaching the image for reference.

@shukku11  
I would say it’s because of the padding. Try using the following in your .box class: box-sizing: border-box;

That wasn’t it ☹ I see that my code has `box-sizing` applied to all the elements, yet to no avail.
