Animating individual letters in a heading is a popular technique for creating dynamic, engaging text effects. To achieve this, you first need to split the text of your heading into separate elements—typically span tags—so that each letter can be targeted and animated independently. This process involves taking the string from your heading, breaking it into an array of characters, and wrapping each one in a span. Spaces are usually replaced with a non-breaking space to preserve layout.

Once each letter is wrapped in its own span, you can use Anime.js to animate them. By targeting all the letter spans, you can apply properties such as movement, opacity, or scale. The real magic comes from using Anime.js's stagger helper for the delay property. This causes each letter's animation to begin slightly after the previous one, creating a visually appealing wave or reveal effect across the heading. You can adjust the duration and the stagger amount to control the speed and feel of the animation, making it subtle or dramatic as needed for your project. Staggered animations are especially effective for drawing attention to headings or introducing key messages with style.
