Preventing the use of fixed positioning on a navigation bar with the CSS filter property

I successfully created a fixed navigation bar that worked perfectly on my webpage. However, when I added a filter (brightness) to an image on the page, the navigation bar disappeared. I tried various solutions including using pseudo-elements and adjusting the position property to no avail. I even attempted setting the filter property on the container of the image's child element, but it still didn't work. Can anyone provide guidance on how to maintain a fixed position for the navigation bar while applying a filter to the image? Thank you in advance.

nav {
  position: fixed;
  background-color: #fff;
}

nav ul {
  margin: 0;
  padding: 0;
}

.navbar-brand {
  padding-right: 20px;
}

nav li {
  display: inline-block;
  padding: 10px;
}

nav a {
  color: #000;
  text-decoration: none;
}

nav a:hover {
  color: #ff6600;
  text-decoration: none;
}

.title-image img {
  width: 100%;
  height: 300px;
  filter: brightness(60%);
}
<nav>
  <ul>
    <li>
      <a class="navbar-brand" href="#">Navbar Brand</a>
    </li>
    <li>
      <a href="#">Home</a>
    </li>
    <li>
      <a href="#">About</a>
    </li>
    <li>
      <a href="#">services</a>
    </li>
  </ul>
</nav>

To ensure your nav element is always on top, include a z-index property in your CSS like so:

nav{
  position: fixed;
  background-color: #fff;
  z-index:999;
}
nav ul{
  margin: 0;
  padding: 0;
  }
.navbar-brand{
  padding-right: 20px;
}

nav li{
  display: inline-block;
  padding: 10px;
}
nav a{
  color: #000;
  text-decoration: none;
}
nav a:hover{
  color: #ff6600;
  text-decoration: none;
}

.title-image img{
  width: 100%;
  height: 300px;
  filter: brightness(60%);
}
<nav>
  <ul>
     <li>
       <a class="navbar-brand" href="#">Navbar Brand</a>
     </li>
     <li>
       <a href="#">Home</a>
     </li>   
     <li>
       <a href="#">About</a>
     </li>
     <li>
       <a href="#">services</a>
     </li>
  </ul>
</nav>

If you're having trouble with your navbar disappearing behind an image, don't worry - it's still there, just hidden beneath the image. To bring it to the front, simply add z-index: 10; (or any value greater than 0).

For more information on z-index, check out: https://developer.mozilla.org/en-US/docs/Web/CSS/z-index

Also, remember that any element positioned after your navbar will appear on top of the page. Consider leaving space equivalent to the height of your navbar before adding any content.
