Others have already mentioned the margin: 0 auto; method, but if you wanted an explanation, the browser splits up the available space in whatever container your element is in.

Also important to point out is you'll probably need to give your element a width, too, for this to work correctly.

So, overall:

button {
    display:inline-block; //Typically a button wouldn't need its own line        
    margin:0 auto;
    width: 200px; //or whatever
}
