Understanding Z-Index and How to Resolve Display Issues with MinCart

What is Z-Index?

Z-index is a CSS property that determines the stacking order of overlapping elements on a webpage. Elements with higher z-index values will appear in front of elements with lower z-index values.

The z-index property accepts integer values. The higher the number, the higher the stacking priority. For example:

An element with a z-index of 1 will appear in front of an element with a z-index of 0.

Common Issue: Pop-Up Displaying Behind the Cart Drawer

If your warning pop-up appears behind your cart drawer, the issue might be related to z-index values. By default, MinCart uses a high z-index value to ensure its pop-ups appear correctly. However, in some cases, your cart drawer might also be using an equally high or higher z-index, causing it to overlap the pop-up.

Modern browsers generally handle higher z-index values well, but adjusting this property excessively may lead to compatibility issues with older browsers.

Solution

Preferred Approach: Adjust the Cart Drawer’s Z-Index

If possible, have a developer reduce the cart drawer’s z-index value to avoid conflicts. This ensures better compatibility and minimizes potential issues with older browsers.

Alternative Approach: Adjust the Pop-Up’s Z-Index in MinCart

You can also increase the z-index of the MinCart pop-up to resolve the issue. Here's how:

Open MinCart’s Custom CSS section.
Add the following code:

#mincart-popup-container {  
      z-index: [Enter a higher numerical value than the cart’s z-index];  
    }

Replace [Enter a higher numerical value than the cart’s z-index] with a number greater than your cart drawer’s z-index value.

Note

While adjusting the z-index should resolve the issue, the preferred approach is to reduce the cart drawer’s z-index if you have access to a developer.
