Q1297 How can I have a slide show, not of images, but of HTML pages?

<style type="text/css"><!--
.hidden  { position: absolute; visibility: hidden; }
.visible { position: absolute; visibility: visible; }
//--></style>

<script type="text/javascript" language="JavaScript"><!--
function set(What,Value) {
    if (document.layers && document.layers[What] != null) document.layers[What].visibility = Value;
    else if (document.all) document.all[What].style.visibility = Value;
}

var layers = 5;
var layer = 1;

function next() {
  if (layer < layers) {
    set('myLayer' + layer,'hidden');
    set('myLayer' + (++layer),'visible');
  }
}

function prev() {
  if (layer > 1) {
    set('myLayer' + layer,'hidden');
    set('myLayer' + (--layer),'visible');
  }
}
//--></script>


<form>
<input type="button" value="prev" onClick="prev()">
<input type="button" value="next" onClick="next()">
</form>

<span name="myLayer1" class="visible">
Slide 1
</span>


<span name="myLayer2" class="hidden">
Slide 2
</span>

<span name="myLayer3" class="hidden">
Slide 3
</span>

<span name="myLayer4" class="hidden">
Slide 4
</span>

<span name="myLayer5" class="hidden">
Slide 5
</span>
