Reveal effects are a cornerstone of polished web animation. These effects smoothly introduce content blocks or images as they become visible, creating a sense of flow and guiding your user's attention. Reveal animations are especially effective for landing pages, feature sections, or any scenario where you want to draw focus to new content as users scroll or interact. The core principle of a reveal effect is to transition elements from a hidden or subtle state—such as off-screen or transparent—into full view in a visually appealing way. This can make your site feel more dynamic and engaging, while also improving the user's perception of performance and interactivity.

You should use reveal effects when you want to highlight important sections, reduce cognitive load by not overwhelming users with too much content at once, or simply add a sense of delight as users explore your page. However, it's important to use them judiciously: overusing reveal animations can distract users or slow down their experience.
