Here's what I got. I'm trying to center pandora, rocket league and chess.com in the #header div. Right now they're on the left.
<!DOCTYPE html>
<html>
<head></head>
<body>
<link type="text/css" rel="stylesheet" href="abc.css"/>
<div id="top"></div>
<div id="header">
    <div class="hovimg">
        <a href="https://www.chess.com">
            Chess.com
            <span>
                <img src="https://tmp-m.org/wp-content/uploads/2015/02/chess.jpg" height="100px" width="180px"/>
            </span>
        </a>
    </div>
    <div class="hovimg">
        <a href="https://www.pandora.com">
            Pandora
