Troubleshooting navigation bar problems: dealing with overlapping and padding challenges in

I'm exploring how to create a hover effect with a bottom border that overlaps with the parent div (navbar) bottom border. I've applied margin:0px and padding:0px to the navbar container.

I'm unsure how to make the hover bottom border effect overlap with the parent bottom border. Take a look at a snapshot of the current state here.

You did not include your code, but I have tried my best to understand your issue. I hope I have correctly understood it and will be able to solve your problem.

li.nav-item {
    padding: 10px;
    position:relative;
}
li.nav-item:hover{
    border-bottom: 5px solid red;
    margin-bottom: -5px;
}
nav.navbar{
    border-bottom: 8px solid blue;
    padding: 0px !important;
}
<nav class="navbar navbar-expand-lg fixed-top navbar-light bg-light">
       <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavDropdown">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse justify-content-between align-items-center w-100" id="navbarNavDropdown">
      <ul class="navbar-nav mx-auto text-md-center">
        <li class="nav-item active">
          <a class="nav-link" href="#">Item1</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Item2</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Item3</a>
        </li>
    </div>
  </nav>

To achieve the desired effect of overlapping the blue line, you will need to adjust the positioning CSS property. In addition, consider modifying the padding and margin of the blue line to eliminate any spacing between the elements.

Experiment with the position, padding, margin, and "!important" declarations:

.blueline{
  margin:0px;
  padding:0px;
}
.menu{
  padding-bottom:0px!important;
  margin-bottom:0px!important;
}

If you want the grey line to overlap, utilize CSS position:relative and absolute to stack elements on top of each other.
