CSS navbar issue: The positioning of the text selection rectangle and drop-down menu is causing problems

While working on creating a navbar, I encountered an issue when hovering over an item (such as "Company") to display the dropdown menu below.

The problem lies in the positioning of the green selection rectangle, which is currently too close to "Company," almost appearing as if it's underlining it. My desired placement for the green rectangle is much lower, precisely at the lower edge of the navbar. Additionally, I aim to improve the drop-down menu positioning, as it seems to overlap the navbar. The desired result is shown here:

I suspect the issue could be related to:

  • The padding and margin of the navbar;
  • The padding and margin of the navbar items (potential conflicts);
  • The line-height; or

Other possible factors that I haven't identified yet.

document.addEventListener("DOMContentLoaded", function () {
    const dropdowns = document.querySelectorAll(".nav-item.dropdown");

    dropdowns.forEach(dropdown => {
        dropdown.addEventListener("mouseenter", function () {
            const menu = this.querySelector(".dropdown-menu-horizontal");
            if (menu) menu.style.display = "flex";
        });

        dropdown.addEventListener("mouseleave", function () {
            const menu = this.querySelector(".dropdown-menu-horizontal");
            if (menu) menu.style.display = "none";
        });
    });
});

Thank you for your help!

To maximize the height of the nav links on the right, follow these steps:

  1. Add a align-items-stretch class to the container to stretch the items vertically
  2. Apply the h-100 class to the ul element to make it take up 100% of its parent's height
  3. Set the height of the nav-link to 100% and align it vertically using Flexbox
.navbar-nav .nav-link {
    height: 100%;
    display: flex;
    align-items: center;
}
  1. Add an align-self-center class to the navbar-toggler button to prevent vertical stretching

  2. For dropdown positioning:

.dropdown-menu-horizontal {
    top: 97% !important;
}
  1. Override any padding in the Navbar if needed
.navbar {
    padding: 0 !important;
}

document.addEventListener("DOMContentLoaded", function () {
const dropdowns = document.querySelectorAll(".nav-item.dropdown");

dropdowns.forEach(dropdown => {
    dropdown.addEventListener("mouseenter", function () {
        const menu = this.querySelector(".dropdown-menu-horizontal");
        if (menu) menu.style.display = "flex";
    });

    dropdown.addEventListener("mouseleave", function () {
        const menu = this.querySelector(".dropdown-menu-horizontal");
        if (menu) menu.style.display = "none";
    });
});
});
* {
    box-sizing: border-box;
}
