The Fade In effect in jQuery causes my fixed header to overlap with images on the page

This is the javascript snippet using jquery

<script type="text/javascript>
  $(document).ready(function () {
    $('#showhidetarget').hide();
    
    $('a#showhidetrigger').click(function () {
        $('#showhidetarget').toggle(150);
      });
    });
</script>

Below is my CSS for a sticky header navigation bar

#nav {
  background-color: #001f22;
  height: 30px;
  width: 100%;
  position: fixed;
  list-style-type: none;
  margin-top: 0px;
  margin-bottom: 0;
   float: left;
   margin-right: auto;
   margin-left: auto;

This is the HTML structure of the Navigation Bar

<div id="nav"> <ul>
   <li><a href="#home">HOME</a></li>
   <li><a href="#about">ABOUT</a></li>
   <li><a href="#portfolio">PORTFOLIO</a></li>
   <li><a href="#contact">CONTACT</a></li>
</ul>
</div>

CSS for image fade-in effect

.fade {
 opacity: 0.5;
 transition: opacity .50s ease-in;
 -moz-transition: opacity .50s ease-in;
 -webkit-transition: opacity .50s ease-in;
}

.fade:hover {
   opacity: 1;
 }

.fade:visited {
   opacity: 1;
}

I have an issue where the fading images overlap the fixed navbar. How can I prevent this?

Answer №1

Set a z-index for the navigation bar and apply it to the fadeIn elements.

Ensure that the z-index of the navigation bar is higher, such as:

.fade {
    opacity: 0.5;
    transition: opacity .50s ease-in;
    -moz-transition: opacity .50s ease-in;
    -webkit-transition: opacity .50s ease-in;
    z-index: 10;
}

#nav {
    background-color: #001f22;
    height: 30px;
    width: 100%;
    position: fixed;
    list-style-type: none;
    margin-top: 0px;
    margin-bottom: 0;
    float: left;
    margin-right: auto;
    margin-left: auto;
    z-index: 20;
}

Answer №2

Are you familiar with the CSS property "z-index"? The z-index determines which element appears on top. An element with a higher z-index will overlap an element with a lower z-index.

For example, you can set the z-index for the header to 999:

#nav {
    z-index: 999;
}

And then set the z-index for the images to a value below that.

I hope this information is helpful.
