What is preventing my overlay from covering the bootstrap navigation bar?

I'm working on implementing an overlay feature in my project to prevent users from interacting before the content is fully loaded. I have included the following overlay code:

.overlay {
  opacity: 0.5; 
  background: #000; 
  width: 100%;
  height: 100%; 
  z-index: 10;
  top: 0; 
  left: 0; 
  position: fixed; 
}

The issue I am facing is that the overlay covers 100% of the entire page except for the bootstrap navigation bar. Can you please assist me with making the overlay cover the bootstrap navigation bar as well?

<div class="overlayIndex"></div>
<div class="navbar navbar-default navbar-static-top navbar-fixed-top">
  <div class="container">
    <div class="row">.......</div>
  </div>
</div>
<div ng-view="" autoscroll="true"></div>

Answer №1

To ensure your overlay covers the entire viewport, adjust your z-index to 1031. This will place it higher than Bootstrap's navbar-fixed-top, which uses a z-index of 1030.

Here is the CSS for Bootstrap's navbar-fixed-top class:

.navbar-fixed-top {
  position: fixed;
  right: 0;
  left: 0;
  z-index: 1030;
}
