Here’s some CSS that I used to make a pretend “Terminal Screen:”

You can see an example here.

/* my [typed] Piece of Paper CSS */

html{height: 100%;} 

body {
  font-family: terminal, sans-serif;
  color: #00FF33;
  padding: 20px 20px 20px 20px;
  margin: 0px;
  background-color: #4682B4;

}

/* The Terminal Window */
#main
{ width: 640px;
  height: 480px;
  padding: 10px 10px 10px 10px;
  margin-left: auto;
  margin-right: auto;
  background: #000000;
  color: #00FF33;
}

#top {
  position:absolute;
  padding: 50px 50px 50px 50px;
  margin-left: 3cm;
  margin-right: auto;
  background: #FFFFFF;
  color: #000000;
  width: 780px;
  height: 150px;
  top: 50px;
  bottom: 100px;

}

a:link {color: #ffffff}     /* unvisited link */
a:visited {color: #ffffff}  /* visited link */
a:hover {  /* mouse over link */
  color: #FFf0FF

}
a:active {color: #0000FF}   /* selected link */ 

/* positioning - left, right and center */
.left
{ float: left;
  padding: 0px 8px 0px 0px;
}

.right
{ float: right;
  padding: 0px 0px 0px 8px;
}

.center
{ display: block;
  text-align: center;
  margin: 0 auto;
}
