Slider Orientation and HTMLpage scaling over Inquisit Web (Player)

Hi All-
Thanks in advance for any assistance.  I have two issues that have eluded my lack of intelligence for weeks.  One at a time: 

1. I cannot figure out how to get this basic slider script to gyroscopically orient to a horizontal position on handheld devices when accessing via Player (now 6.3.1).  The Apple iPad, Apple iPhone, Android tablet and Android cell phone will not orient horizontally.  Windows desktop has no issue orienting horizontally through Player 6.

Re. #1, you may have to explicitly specify the canvas. I.e.

<defaults>
/ canvasaspectratio = (3,4)
</defaults>

or

<defaults>
/ canvassize = (99%,100%)
</defaults>

if you want portrait orientation on iPad, iPhone, etc, and

<defaults>
/ canvasaspectratio = (4,3)
</defaults>

or

<defaults>
/ canvassize = (100%,99%)
</defaults>

if you want landscape orientation

Re. #2, not sure how to say anything about that without the actual HTML page.

Thanks,

You'll want to make sure the image is actcually scaled relative to the viewport. E.g. something like this:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>NVT</title>

<style>
.center {
  text-align: center;
  }
.left {
  text-align: left;
  }
body {
background-color: white;
font-family: arial;
color:black; 
font-size: 3.5vh;
}
h1 {
font-size: 5vh;
}
p {
font-size: 3.5vh;
}
p.bigger {
font-size: 4vh;

li {
font-size: 3.5vh;
}
.blue {
  color: blue;

.yellow {
  color: yellow;
}
.red {
  color: red;
}
.green {
  color: lightgreen;
}
</style> 
 
</head>

<body>
  <div class = "center">
   <img style="width: 80vw" src="stop_and_wait_screen.png" />
  </div>
</body>
