Z-Index is a CSS property that controls the stacking order of elements on a webpage. It determines which elements appear on top of others when they overlap, essentially working along an imaginary Z-axis that runs perpendicular to the screen. By assigning different z-index values to elements, web designers can create complex, layered visual effects, ensuring that critical content, such as navigation menus or modal windows, remains accessible and visible above other page content.


The Significance of Z-Index in Web Design

Effective use of the z-index property is crucial in web design for managing the visual hierarchy and user interface elements on a page. It allows for the creation of dynamic, interactive experiences, where elements such as dropdowns, overlays, and pop-ups function as intended without disrupting the overall design.

Understanding and correctly applying z-index values can significantly enhance a website’s usability and aesthetic appeal, making it a key tool in the arsenal of web developers and designers aiming to craft engaging and intuitive digital environments.
