I cannot see my error. Want a black background for space id

<style type="text/css">
#wrap { width: 90%; min-width: 50px; max-width: 900px; background-color:black; }
#space {
 position: relative; z-index:200; margin: 40px auto; padding: 40px .5%; text-align: center; width: 90%; max-width: 500px; min-width: 50px;  height:auto; background: #000;  display:table-cell; vertical-align: middle;  }
 #space h3 { color: #FC0; }
#space img {  display: block; margin: 40px auto; padding: 5px; border: none; height: auto; width: 50%; min-width: 25px; max-width: 400px; }
#textbox { margin: 5px auto; width: 90%; min-width: 200px; max-width: 600px;padding: 10px;  color: #000; background: #fff; overflow: hidden;  } 
Also want #space img to be "responsie" and reduce to 25px
