In this particular use-case (i.e, setting the background image at load
time), tagging *both* scripts with RawMarkup has a subtle twist:
"document.body" *does not yet exist* when the <head> of the document is
processed. While you can *define* the ChangeIt(...) function in the head,
but you can't invoke it until document.body has actually been created. To
work around this, while still using RawMarkup for both script pieces, you
can invoke the ChangeIt() function from within an "event listener" that
waits for the "load" event to complete... .like this:
<script>
window.addEventListener("load", ChangeIt, false);
</script>
