tips for concealing bootstrap css hover/activate color when scrolling beyond the top

Looking for help with my Bootstrap HTML code:

<nav>
  <ul>
    <li><a>1</a></li>
    <li class="active"><a href="#">2</a></li>
    <li><a>3</a></li>
  </ul>
</nav>
<footer>
back to top
</footer>

In the image provided, the active element 2 covers part of the footer when scrolling. How can I adjust it so that it stays hidden within the footer like the other elements when scrolling down?

Answer №1

If you want to make sure the footer element is displayed on top, consider increasing its z-index.

Check out this helpful resource on CSS z-index property for more information.

Here's an example:

div {
  position: relative;
  width: 100px;
  height: 100px;
}

.first-div {
  background: red;
  
  /* adjust this z-index value */
  z-index: 2;
}

.other-div {
  position: absolute;
  background: lime;
  top: 60px;
  left: 60px;
  
  /* adjust this z-index value */
  z-index: 1;
}
<div class="first-div">
  <span>first div</span>
</div>

<div class="other-div">
  <span>other div</span>
</div>

Answer №2

It is important to compare the css z-index values of the two elements in question. In order for proper display, ensure that the footer's z-index is greater than that of the menu element.
