Instead of adding the style to the header, apply it directly to the <html> element. Then you can remove it again easily by putting something like this inside the negativar function:

var html = document.getElementsByTagName('html');

if (html.getAttribute('style')) {
    html.setAttribute('style', '');
} else {
    html.setAttribute('style', 'YOUR STYLE HERE')
}

Specify html and body height and white background instead of transparent:

$("button").click(function () {
  $("html").toggleClass("inversed");
});
html, body {
  background: white;
  height: 100%;
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

body {
  padding: 1em;
}

.inversed {
  -webkit-filter: invert(100%);
  filter: invert(100%);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button>Inverse</button>
