Mastering CSS: Changing Background Images for Child Divs

Are you struggling to apply different background images to child divs in your HTML structure? If so, you’re not alone! This is a common scenario for front-end developers who want to personalize styles for individual elements based on their position within a parent. In this guide, we will explore how to effectively target and style child divs using CSS, ensuring each one can have a unique background image.

Understanding the Problem

You have a list of items in HTML and want to assign each blocks-item-image a different background image based on its position. Initially, you may have tried using the nth-child selector, but you found out that it wasn’t working as expected. The blocks-item-image in your implementation ended up with the same background image for all elements.
