Mix-blend-mode difference not working and background image of parent is in front of children regardless of z-index

Problem:

The mix-blend-mode: difference is not working, and the background image of the parent is in front of the children regardless of the z-index.

Solution:

The issue was resolved by adding position: relative; z-index: 2 to the .header-container class. This allows the mix-blend-mode: difference to work correctly and places the children in front of the parent's background image.

.header-container {
  position: relative;
  z-index: 2;
}

Additionally, to make the mix-blend-mode: difference work effectively, the following changes were made:

• A background color of white was added to the background property.
• The mix-blend-mode was applied to the .header-container class.
• The text color was changed to white and kept on the difference blend, even on a white backdrop.

.header-container {
  background: white;
  mix-blend-mode: difference;
}

h1 {
  color: white;
  mix-blend-mode: difference;
}

Additional Solution:

In another case, the issue was resolved by adding mix-blend-mode: difference; to the .header-container class and color: white; mix-blend-mode: difference; to the h1 element.

.header-container {
  mix-blend-mode: difference;
}

h1 {
  color: white;
  mix-blend-mode: difference;
}

These solutions effectively address the issues related to mix-blend-mode: difference and ensure that the background image of the parent is placed behind the children, respecting the z-index values.
