Form input box issues

My form input boxes are shrinking in size when hovering over them? None of the other form elements are doing this…

My Marketing Solutions -

On the contact page you can see that other form elements are not causing the same effect.

Thanks for the help

The input elements’ hover state has a 1px border applied, but the normal state does not. {
  float: right;
  font-size: 1em;
  padding-left: 5px;
  padding-top: 2px;
  border:1px solid #f0f0f0;

Thank you - Seems to be working fine now…
