I have a PSD file where I have the following line:
width: 4px
However, when I add a border like this:
border: 4px solid #000
my browser shows it with an 8px width.
Does my border have it's own paddings?
This is because it adds a border around the div. So there's 4px on top, and 4px on bottom. If you change it to border-top, or border-bottom, it will just be 4px.
