What is the best way to position a drop-down box in front of images?

After creating a gallery page to showcase website images, I encountered an issue where the images overlapped with the drop-down boxes of my navigation bar. Unfortunately, this means that I am unable to click on the drop-down boxes in order to navigate to other pages. Is there a method to prioritize the drop-down boxes over the images so that they function properly? Below is the code snippet:

* {
        padding: 0;
        margin: 0;
        box-sizing: border-box;
      }

      body {
        font-family: sans-serif;
        background-color: #788bc8;
        min-height: 100vh;
        overflow-x: hidden;
      }

      span {
        color: white;
      }

      .navbar {
        background-color: #d0f0c0;
        height: 80px;
        width: 100%;
        display: flex;
        align-items: center;
        justify-content: space-between;
        padding: 0 3%;
      }

      .logo {
        font-size: 45px;
      }

      .logo a {
        color: red;
        text-decoration: none;
      }

      .navbar ul {
        display: flex;
        list-style-type: none;
      }

      .navbar ul li {
        padding: 10px 25px;
        position: relative;
      }

      .navbar ul li a {
        color: black;
        text-decoration: none;
        font-size: 22px;

        transition: all 0.2s;
      }

      .fas {
        float: right;
        margin-left: 10px;
        padding-top: 3px;
      }

      .navbar ul li a:hover {
        color: #4dac62;
      }

      .navbar ul li :where(.dropdownda, .dropdownfa) ul {

        margin: 10px;
        text-align: center;
      }

      .navbar ul li :where(.dropdownda, .dropdownfa) ul li {
        width: 200px;
        padding: 10px;
      }

      .dropdownda,
      .dropdownfa {
        display: none;
        position: absolute;
        left: 0;
        top: 100%;
        background-color: #d0f0c0;
      }

      .navbar > ul > li:hover :where(.dropdownda, .dropdownfa) {
        display: block;
      }

      .main {

        column-gap: 10px;
        row-gap: 10px;
        padding: 10px 0px;
      }

      img {

        object-fit: cover;

The images may not be visible within the snippet, however, you can observe how the drop-down box gets hidden behind the image placements. Even applying the !important rule to the drop-down boxes did not resolve the issue.

Answer №2

To control the vertical stacking of elements in CSS, assigning a z-index value to both the image and dropdown is essential. The higher the z-index, the closer an element will be positioned towards the top of the page.

img {
    z-index: 0
}
.dropdown {
    z-index: 1
}

The specific numerical values assigned to the z-index can vary, as long as the dropdown's z-index is greater than that of the image.

Answer №3

One way to ensure dropdowns appear above images is by setting the z-index property to 1 for dropdowns and 0 for images.
