Padding count in "regular" Box Model differs from Webflow – or am I wrong?

Well.
I feel kinda stupid. But in the Box Model the padding of a box also counts in the total dimension of an element. But not when i’m doing it in Webflow. (Which is easier to calculate - thanks by the way). But what is the reason and how/where it works?

My Codepen Test
My Webflow Project

My CSS of the Child Items

.box {
  display: block;
  width: 17%;
  margin: 2%;
  background:#9afaa3;
  color: #225489;
  padding: 2%;
}

.box-2 {
  display: block;
  width: 20%;
  margin: 2.5%;
  background:#9afaa3;
  color: #225489;
  padding: 4%;
}

25

If creating a div block with a width of 20%, then adding padding 4%. Then the box will not be 24% in width. Padding pushes the elements inside the box.

This goes for Webflow as well. :slight_smile:

Also, values in % on padding top or bottom are relative to the computed width of the parent element (ie. containing block).

Thanks for your fast reply. I need to study your answer while having lunch. :slight_smile:

I do understand the dependency of the padding value to its parent.

But still, why does it differ from my Codepen Test?
