Z-Context is a Chrome DevTools Extension developed by gwwar that provides valuable information about stacking contexts and z-index values in the elements panel. It is a useful tool for web developers who want to ensure correct usage of z-index values and avoid common mistakes.

One of the key features of Z-Context is its ability to identify if the current element creates a stacking context and why. This information is crucial for understanding the behavior of elements in the stacking order. Additionally, Z-Context displays the parent stacking context of the current element, allowing developers to trace the hierarchy of stacking contexts.

Another important feature of Z-Context is its ability to show the z-index value of each element. This helps developers easily identify the stacking order of elements and troubleshoot any issues related to z-index conflicts.

Overall, Z-Context is a powerful tool for web developers working with stacking contexts and z-index values. With its clear and concise display of relevant information, it simplifies the debugging process and ensures correct usage of z-index values.
