HTML button not linking to CSS

I'm self-teaching myself CSS and is using W3schools

I created a button where once clicked it'll send you to another page, which works, but now I wanted to style it but my CSS isn't doing anything and I'm thinking it's the naming convention.

input [type=submit] {
  -webkit-appearance: button;
  -moz-appearance: button;
  appearance: button;
  background-color: white;
}

<form action="info-page-1.html">
  <input type="submit" value="What's going on?">
</form>
