Trying to hover over an icon that triggers the h4 to transition margin, display and background.
Is this to correct way to select one element:hover{} but affect another element?

.nav_item i:hover h4

Please see the code pen link below:

ps I put x and o in place of the icon's, font-awesome wouldn't load.

css

.nav_item h4 {
      -webkit-transition: all 1s ease;
       transition: all 1s ease;
       width: 40rem;
       display: none;
    }

.nav_item i {
  width: 5rem;
}

.nav_item i:hover h4 {
  background-color: #b4fdd2;
  width: 20rem;
  display: block;
}

HTML

    <div class="nav_box">
        <div class="nav_ul">
            <div class="nav_item">
                <span class="d"><i class="fas fa-home">O</i></span>                    
                <h4 class="h4">Home</h4>
            </div>
            <div class="nav_item">
                <span class="d"><i class="fas fa-barcode">X</i></span>                    
                <h4 class="h4">Shop</h4>
            </div>
            <div class="nav_item">
                <span class="d"><i class="fas fa-book">O</i></span>                    
                <h4 class="h4">Learn</h4>
            </div>                                                             
            <div class="nav_item nav_down">
                <span class="d"><i class="fas fa-key">X</i></span>
                <h4 class="h4">Sign in</h4>
            </div>
        </div>
    </div>
</nav>

You can't access ancestors in CSS, but you can select siblings with the + (next sibling) selector. The h4 is the next sibling of span you can do: 

.nav_item span:hover + h4 {
  background-color: #b4fdd2;
  width: 20rem;
  display: block;
}

You will need to do further adjustments to your code for it to work properly.

Well since you wrap your h4 text and font you can use span:hover instead of i hover.

Please note if you use "+" it will apply only to first H4 tag next to span If you use "~" it will apply to every H4 tag next to span. Check example here https://jsfiddle.net/dkn6zch1/3/
