+### Toggle between modals
+
+Toggle between multiple modals with some clever placement of the `data-bs-target` and `data-bs-toggle` attributes. For example, you could toggle a password reset modal from within an already open sign in modal. **Please note multiple modals cannot be open at the same time**—this method simply toggles between two separate modals.

 ### Change animation
 
 The `$modal-fade-transform` variable determines the transform state of `.modal-dialog` before the modal fade-in animation, the `$modal-show-transform` variable determines the transform of `.modal-dialog` at the end of the modal fade-in animation.
