How to add watermark image to your website? It’s pretty simple!

First, you should make a image as your watermark image apparently.

Then, add this code to your css file.

body::after {
  content: '';
  position: fixed;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  background: url('./watermark.png');
  opacity: 0.3;
  pointer-events: none;
}

The point is the pointer-events property.

As MDN saying:

It sets under what circumstances (if any) a particular graphic element can become the target of pointer events.

The value none instructs the pointer event to go “through” the element and target whatever is “underneath” that element instead.
