Solution to the AnimatePresence Problem and CSS Overflow Hidden

If you are working on projects that involve animations and libraries like Framer Motion, you may have encountered various challenges. One of these challenges is the interaction between animations and CSS, particularly the overflow:hidden property. However, don't worry; there’s always a solution!

First of all, let's talk about the overflow:hidden property. It can cause issues where all additional content that comes out of the box may not be displayed. Many developers face this problem when they want to avoid these overlaps. However, when animations are involved, this property can lead to animations not functioning correctly or causing some elements to become temporarily hidden.

Now let's focus on AnimatePresence, which is available in Framer Motion. The main task is to ensure that animations are handled correctly before being completely removed from the DOM, so they work as intended. Many users may want to handle animations elegantly, but they often face issues like this CSS overflow:hidden.

The solution to this problem usually involves adjusting CSS to ensure that the animations are correctly displayed. However, it’s essential to ensure that the animations are performed continuously and without a performance drop. Generally, it’s something to keep in mind, as the DOM structure and the expected animations should be configured in such a way that interactions are smooth.
