1,436 PointsIn the box model png you are meant to replicate, the L-R margins are at 416.5px, which makes the assignment unclear.
I assumed I needed to replicate that box model exactly, AND center the .box at the same time. This gave me a problem that I was trying hard to solve unnecessarily. I feel that it would be helpful for people in the future- if you address the goal more specifically regarding the margin in the png.

Any element in css is a inline or block element. Here div with the class of .box is a block level element which by default takes the full width & height of its parent element if we would not define the width and height ourselves. if you remove the max-width property and give it a width:100% and than it will take whole space. Now it has the max-width property, so the space left after giving that will be the margin on right side. After defining the property as margin:auto the browser will calculate the margin from all the sides of the .box and make it center.
NOTE: pls try to inspect the element in the browser and experiment the adding and removing the properties of the element.
you can read explanation on the MDN website. https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Box_Model/Introduction_to_the_CSS_box_model
Hope this will help you
thanks
