This article provides an in-depth examination of the common issue where position: sticky elements fail to function properly within flexbox containers. The problem stems from the default align-items: stretch behavior in flexbox, which causes all flex items to be stretched to the container's height, eliminating the necessary scroll space for sticky positioning. By analyzing CSS specifications and browser implementation details, the article demonstrates how align-self: flex-start overrides this default behavior and restores expected sticky functionality. Browser compatibility considerations and complete code examples are included to illustrate both the problem and solution.

This article explores the core reasons why images are stretched instead of retaining their aspect ratio in Flexbox layouts.
