create animations

Make animations for the delete button as well as hover animations for hovering over a reminder. Also make an animation for the save button.

Delete button: When the user is not hovering over the delete button, keep it red normally (a red x), when the user is hovering over it, make it a nice round button whose background is a bit darker than the other buttons.

Have a liquid glass look for the normal reminders, they should function like normal but have that liquid glass look to it.

For the save button, make it rounded, have hover animations as well also with the liquid glass look.

Start by locating the delete button, save button, and reminder styling in the JavaScript frontend, then inspect their current hover and normal states. Done means the delete and save buttons have the requested rounded hover animations, reminders have the liquid-glass appearance, and the described red delete-button behavior is preserved.
