Adding space and font changes to second <li> in the <ul>

I added a css element like this:

ul.spaced li 
{ 
    margin-bottom: 10px; 
}

And I try to use it like this:

<li class="spaced">Hike description test</li>

But it doesn't seem to add the space at the bottom.

Also, how can I make the inner

You can see an example of the page I am working on here: http://www.comehike.com/community/hiker_public_profile.php?community_member_id=2

Thanks!

Your selector is wrong - you don't want to look for li inside ul.spaced, you want li.spaced inside ul. Also, if margin-bottom doesn't work, you can probably get away with just changing it to padding-bottom.

ul li.spaced
{ 
    padding-bottom: 10px; 
    font-weight: normal;
}
