If you want to style your menu items, consider placing them within a span
tag and then styling that specific DOM element. Below is an example snippet to demonstrate this:
.Nav_bar_links div {
margin: 0% 1%;
padding: 20px 10px;
font-weight: 500;
display: inline-block;
}
.Nav_bar_links div:hover {
background: #222222;
color: #e50000;
}
.Nav_bar_links div:hover span {
padding-bottom: 5px;
border-bottom: 3px solid #FF0000;
}
<div class="Navigation_bar">
<img src="images/w-logo-1.png" height="7%" width="7%" align="middle">
<div class="Nav_bar_links" align="right">
<div class="active"><span>HOME</span></div>
<div class="add_on"><span>ABOUT</span> <i class="fas fa-caret-down"></i></div>
<div><span>SPONSORS</span></div>
<div><span>GALLERY</span></div>
<div><span>NEW & UPDATES</span></div>
<div><span>CONTACT US</span></div>
</div>
</div>
