A 15-second explainer animation made for the new app ChatSoon, built with pure HTML, CSS, and JS only, without any other video tools. Useful as a reference for app launch announcements, feature demos, and social media promo clips, and as an example of using a lightweight web animation for product explainers.
You are an expert web designer. Build a stunning, production-ready page with
a bold hero section, smooth CSS transitions and a carefully tuned dark palette.
Use a neutral background, generous rounded corners and one electric accent color.
Structure the layout with a sticky header, feature grid, social proof and a final
call to action. Keep typography tight, spacing consistent and motion subtle.
