In CSS, the z-index property is used to control the stacking order of elements on a webpage.

When elements overlap on a webpage, the z-index property determines which element appears on top of the others.

The z-index property takes a numerical value, with higher values bringing elements to the front and lower values sending elements to the back.

Elements with a higher z-index value will appear on top of elements with a lower z-index value.

Understanding how to use the z-index property effectively is crucial for creating visually appealing and functional web designs.

By adjusting the z-index values of elements, developers can control the order in which elements appear on the screen, allowing for more dynamic and interactive layouts.

In addition to controlling the stacking order of elements, the z-index property can also be used in conjunction with other CSS properties to create more complex layouts and effects.

For example, z-index can be combined with positioning properties like absolute or relative to create layered designs or parallax scrolling effects. Overall, the z-index property is a powerful tool in CSS that allows developers to control the visual hierarchy of elements on a webpage, enabling them to create more engaging and interactive user experiences.

By mastering the z-index property, developers can take their web design skills to the next level and create truly standout websites.
