I'm working with an HTML element that can contain a child with the ID 'slideshow'
<div id='content'>
<div id='slideshow'>
</div>
</div>
Alternatively, it could have a different child like this:
<div id='content'>
<div id='other'>
</div>
</div>
My goal is to style #content only when it has a child with the ID 'slideshow.'
Is there a way to achieve this?
