Question

The problem is very simple:

    <div id="main-content">
<ul>
    <li>
   <div class="post-row">
         <div class="post-footer">

               This is the Footer       
                <div class="footer-buttons">
                    <ul>
                        <li>Edit</li>
                        <li>Reply</li>
                    </ul>
                </div>
         </div>
   </div>
    </li>
</ul>
</div>

And now main content:

#main-content ul {
    margin:0;
    padding:0;
}

#main-content ul li {
    display:block;
    list-style:none;
}

And last, footer-buttons:

.footer-buttons {
    float:right;
}
.footer-buttons ul {
    margin:0;
    padding:0;
}
.footer-buttons ul li {
    display: inline;
}

The problem is that the list in .footer-buttons is displayed as block. And in fact when I checked DOM the display: inline is overrided by the #main-content.

From what I know understrand this shouldn’t happen. Or am I wrong and id elements will always override child classes?

Answer 1

You have 2 selectors: #main-content ul li and .footer-buttons ul li . First of them uses id and the second uses class, that’s why the first one is used as more descriptive. Use:

#main-content .footer-buttons ul li { display: inline; }
