Styling navigation bar in wordpress

what?

Hi,

I have a problem with my navigation bar. I know exactly what to do to make it right and where to edit, but I don't know to to get there from css.

I have this piece of code:

<li class="page_item page-item-18"><a href="http://work/zakelijkverblijf/" title="Zakelijk">Zakelijk</a>
<ul class='children'>
	<li class="page_item page-item-212"><a href="http://work/zakelijkverblijf/activiteiten/" title="Activiteiten">Activiteiten</a></li>
	<li class="page_item page-item-207"><a href="http://work/zakelijkverblijf/dagvergaderarrangementen/" title="Dagvergaderarrangementen">Dagvergaderarrangementen</a></li>
	<li class="page_item page-item-210"><a href="http://work/zakelijkverblijf/meerdaagse-vergaderarrangementen/" title="Meerdaagse vergaderarrangementen">Meerdaagse vergaderarrangementen</a></li>
	<li class="page_item page-item-214"><a href="http://work/zakelijkverblijf/personeelsuitjes/" title="Personeelsuitjes">Personeelsuitjes</a></li>
 
</ul>
</li>

I would like to add an attribute for that ul class="children". I can't add the attribute to .children because I want that option for that particular li class="page_item page-item-18".

So finally, this is the question: How can I add an css attribute for that inner ul class="children" that would apply only to that li class="page_item page-item-18" ?

Thanks,

Nihilistar

So, like .page-item-18 .children { background-color: #f00; } ?

Nope it's not working

Yes it does.
The only way it won't is if you have styles that are more specific then the one I posted.
Since you have not supplied a link or all of your html and css that we request, it's about as much help as I am able to supply.
