Code Challenge: width height and property

Hi,

So I am kind of stuck at step 3, and here is the question:

Currently, the width of the div with the class 'main' is set to 400px, but the padding applied is adding an extra 40 pixels to its total width. Add a property that forces the padding into the width of the div.

I use div as my selector and I typed padding as 40px. I apply this code as the following: box-sizing: border-box;

Then It tells me that my box-sizing property is wrong? Did I reverse something?

Lawrence, I know you ended up figuring it out, but could you post the answer anyways? I am currently having difficulties with this one as well and others may have the same problem in the future.

Thanks!

Here is the answer, in case anyone else is having difficulties:

div {
  width: 400px;
  box-sizing: border-box; 
}

Thank you Guil!

By the way, I do have bit of problem with understanding relative and absolute positioning. I know absolute positioning is assign on first position of the ancestor element. Than relative element sets to its normal position. But I do not quite understand how these boxes are stacking on top of each other in a certain arrangement with combination of relative and absolute positioning pseduo element. Could you explain more?

Thanks!
