What are the potential pitfalls of stacking background images in CSS?

When stacking background images in CSS, it's important to consider the potential pitfalls such as image visibility issues, performance impact due to larger file sizes, and compatibility problems across different browsers. To solve these issues, it's recommended to optimize the images for web use, use CSS background properties like background-size and background-position to control image display, and test the layout across various browsers to ensure consistency.

<style>
    .background {
        background-image: url('image1.jpg'), url('image2.jpg');
        background-size: cover, contain;
        background-position: center, top right;
    }
</style>
