Is it an issue that there are no maple trees growing in the ocean?

It is not an isssue, Gene, only if you make it one
by trying to do something that is impossible standardwize.

More so, if you accidentaly use an id more than once, most browsers will 
forgive you your grave error and only use the first id. 

Also CSS use of id is off-topic here.

However if you want to make a javascript collection of html-elements,
there are many ways to do that.

Most use getElementsBy* [with the 's']:

getElementsByName()
getElementsByTagName()
getElementsByClassName()

--------------------------------------------

However, 
while I hate to acknowledge this,
Javascript being Javascript [sorry Thomas],
there is [dirty?] a way around the html single id-limitation, Gene.

Try:

==========
<style type='text/css'>
div {color:red;}
</style>
<div id=a>1</div>
<div id=a>2</div>
<div id=b>3</div>
<span id=a>not a div</span>
<div id=a>4</div>

<script type='text/javascript'>

var x = document.getElementsByTagName('div');

for (var i = x.length-1;i>-1;i--)
 if (x[i].id == 'a')
  document.write('<br>'+x[i].id+' > ' + x[i].firstChild.nodeValue);

</script>
==========
