How to Adjust the Opacity of a Div's Background Image Only?

Opacity for Div Background Image Only

In web design, setting the right opacity levels can enhance the visual appeal of elements on your page. However, it can be challenging to adjust the opacity of a background image without affecting other elements within the same container. Here's how you can achieve this effect:

One method involves using a CSS pseudo-element, as suggested in the question:

.myDiv {
  background-image: url("your_image.png");
  opacity: 0.5;
}

.myDiv::before {
  background: rgba(0, 0, 0, 0.5);
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
}

This creates a hidden element (::before) that overlays the background image and sets its opacity to 0.5, while leaving the text within the div unaffected.

However, you can also achieve the same effect using a simpler approach:

.myDiv {
  background-image: linear-gradient(rgba(255,255,255,0.5), rgba(255,255,255,0.5)), url("your_image.png");
}

This method creates a linear gradient with two color stops, where both stops specify a semi-transparent white color (#FFFFFF) with an opacity of 0.5, followed by the background image. This ensures that the background image appears with a 50% opacity, while the text inside the div remains fully visible.
