How to center js alert?

Question

JavaScript

There is such button in aspx page

<asp:Button ID="btnDelete" runat="server" Text="Delete" CssClass="button" CommandName="Delete"
                                       OnClientClick="return confirm('Are you sure?');"/>

Is it possible to make the appearing alert box be in the center of the screen, and not at the very top, as it is by default?

Answer 1

The native alert cannot be changed in any way. But sweetalert2 is very easy to change.

Answer 2

It is forbidden.
