Doh! But all of TheDivToShow's *ancestors* would also have to be
visible for that to work. So unless the target div is at the top
level under <body>, it's going to get ugly fast...
But if it *is* at the top level, then as Alex points out, if you can
put everything else in a div or divs:
<body>
<div><!-- everything before it --></div>
<div id='TheDivToShow'>...</div>
<div><!-- everything after it --></div>
<div><!-- there might be several of these --></div>
</body>
...this should do it:
div {
display: none;
}
#TheDivToShow, #TheDivToShow div {
display: block;
}
