Utilize CSS :hover for revealing and concealing HTML elements

Why does the (.nav-element>a:hover) in the given code work properly, but the (.nav-element>a:hover .nav-dropdown1) does not seem to respond? I have attempted various methods to activate it, but is there an issue with the syntax in the rule that is causing it not to work? Below is the complete code that I have:

.nav-contaier {
clear:left;
background-color: #3B3B3B; 
}

.element-container {
background-color:#3B3B3B;
height: 4em;
width: 100%;
margin: auto;
}

.element-container>ul {
width: 80%;
height: 100%;
margin: auto;
display: flex;
}

.nav-element {
text-align: center;
flex: 0 0 20%;
color: white;
display: inline-block;
margin-left: 0;
margin-right: 0;
}

.nav-element>a {
line-height: 4em;
color: white;
height: 100%;
width: 100%;
display: block;
}

.nav-element>a:hover {
background-color: black;

}

.nav-dropdown1 {
display: block;
opacity: 0;
width: 80%;
height: 100%;
margin-left: 10%;
position: absolute;
height: 2em;
z-index: 10;
background-color: blue;
}

.nav-element>a:hover .nav-dropdown1 {
    opacity: 1;
    height: 3em;
 }

 //HTML FROM HERE

    <div class="nav-contaier">
        <nav class="element-container">
            <ul>
                <li class="nav-element"><a href="index.html">Home</a></li>
                <li class="nav-element"><a href="index.html">Menu</a></li>
                <li class="nav-element"><a href="index.html">Lorem</a></li>
                <li class="nav-element"><a href="index.html">Ipsum</a></li>
                <li class="nav-element"><a href="index.html">Contact</a></li>
            </ul>
        </nav>
    </div>
    <div class="clearfix"></div>
    <div class="nav-dropdown1">

    </div>

Answer №1

A definite explanation exists for this.

Utilizing pseudo elements in this manner will solely function on legitimate offspring of the ancestor element.

The sole resolution at this juncture would involve incorporating JavaScript.

A quick side note, based on your HTML framework, it appears you are aiming to construct a nav-dropdown for each listitem. A more efficient approach would be

<ul>
  <li><a>Bar</a> 
    <ul>
      <li><a>Bar dropdown</a></li>
    </ul>
  </li>
</ul>

Various examples are available on how to develop a submenu, the benefits include having a superior HTML setup, and you would actually be able to utilize the pseudo elements you inquired about.
