Sometimes, you want an animation to trigger every time an element enters the viewport—not just the first time. For example, a list of features or steps in a process might benefit from repeated animations as the user scrolls up and down the page. This keeps the experience lively and can help draw attention to important sections, making the site feel more interactive.

To achieve this with AOS, use the data-aos-once="false" attribute on your animated elements. This tells AOS to animate the element every time it becomes visible. Repeated animations can be especially effective for content that users revisit, such as FAQs, testimonials, or interactive guides. However, consider your audience and the context: while repeat animations can enhance engagement, overusing them may distract users or make the interface feel busy.
