Animations and transitions in CSS serve dual purposes: they enhance aesthetic appeal and aid in user understanding of interface changes. For instance, when reordering a list, instant changes can confuse users, but animating the movement clarifies the action. Each list item has a button to move it to the top, with considerations for browsers with differing support for new APIs. A function is abstracted to guarantee proper functionality regardless of support for View Transitions, while providing a visually pleasing fade effect during item movement.
Animations and transitions in CSS not only add fun but also help users understand changes in user interfaces, such as reordering list items.
Animating list items during reordering makes it clear what action has occurred, enhancing user comprehension compared to instant changes.
When a button is clicked, the corresponding list item is moved to the top, with an approach that considers browsers' support for View Transitions.
Using document.startViewTransition enables a smooth transition in updates to the DOM, abstracting support checks to ensure functionality.
