I got a broken box error with CSS lint?

I have a class with padding and height in the same declaration, CSS below:

.header-section {
  padding-top: 3px;
  height: 115px;
  background-color: black;

The error from CSS lint says, "Using height with padding-top can sometimes make elements larger than you expect."

I did setup the box-sizing rule to.Is this something I should change, or is CSS lint being too picky? Thanks in advance for any answers.

It's not really an error, just a warning. Your .header-section will take up 118px of space vertically because you have to add the 3px of padding to the 115px height.

If you use box-sizing: border-box, it will apply the padding to the inside of the element, making the header take up 115px of vertical space, with the 3px of padding applied inside of the element instead of outside of it. So in other words, it's just a warning to make sure you are aware of it, but you don't necessarily have to change it unless you want to.
