Hi Magnus,
Go to dashboard -> appearance -> theme options -> design options -> custom css and add this css. You search button css is not working perfectly

input[type="reset"], input[type="button"], input[type="submit"] {
  font-size:13px;
}

I did not get exactly what are you talking menu button CSS, Could you clearify it? To hide the search button go to dashboard -> appearance -> theme options -> design options -> custom header -> at the button there is options and check it to hide the search button.

I just checked the responsive of your site and its working fine too.

Thank you!
