How Can I Overlap Images in HTML without Using Compositing?

Positioning Overlapping Images in HTML without Compositing

You're looking to display multiple images on a web page, with some positioned on top of others, without resorting to compositing for performance reasons. Let's dive into the solution:

To achieve image overlap, you can use HTML and CSS positioning techniques. Wrap the images within a parent container and apply relative positioning to it. Individual images should have absolute positioning.

Here's an example code snippet:

<div class="parent">
  <img class="image1" src="blue-square.png" />
  <img class="image2" src="red-square.png" />
</div>

.parent {
  position: relative;
  top: 0;
  left: 0;
}

.image1 {
  position: relative;
  top: 0;
  left: 0;
  border: 1px red solid;
}

.image2 {
  position: absolute;
  top: 30px;
  left: 30px;
  border: 1px green solid;
}

In this example, the parent container has relative positioning, allowing the child images to be positioned relative to it. The image1 has relative positioning and stays in its initial position. The image2 has absolute positioning and is offset by 30px from the top and left edges of the parent container.

By using this approach, you can position images precisely without the overhead of compositing. This is especially beneficial for scenarios where you need to display multiple images dynamically or have complex positioning requirements.
