The CSS for the centered-container class in the HTML file contains two justify-content properties. The second justify-content property will override the first one, making the first one redundant and potentially causing confusion.

1. Go to the repository containing the HTML file. (fyne\cmd\fyne\internal\templates\data\index.html)
2. Locate the centered-container class in the CSS.
3. Observe that there are two justify-content properties in the class definition.
4. Notice that the second justify-content property overrides the first one.
