Firefox/Safari setting height as [specified height - padding - border] for input[type=button]

Question

When I use the following CSS:

input[type=button] {
  background-color: white;
  border: 1px solid black;
  font-size: 15px;
  height: 20px;
  padding: 7px;
}
         


        

Answer 1

It makes sense because the height of the element is naturally more than what you set it to. input elements are assigned a height which, in this case, should be enough to contain the text of your element but you set it to a smaller amount. To show this, remove your height setting.
