Nonprofit — Petition / Pledge
A warm, hopeful petition and pledge page for a fictional clean-water charity. It pairs a bold cause statement and impact stats with an animated signature-goal thermometer and progress bar, a validated sign form with optional comment and privacy toggle, a live recent-signatures feed that grows as people sign, and quick share actions. A sticky donate call-to-action and trust badges round out a self-contained, accessible, responsive vanilla build.

Every spring, untreated runoff pours into the East Bank, choking the wetlands that
18,000 residents rely on for clean drinking water. We're petitioning the county council
to fund permanent filtration and restore 40 acres of riverbank habitat.

</html>Petition / Pledge
A campaign-style petition page for the fictional Clear Waters Coalition. The hero leads with the cause — protecting the Rivertown watershed — alongside count-up impact figures (acres to restore, residents served, partner groups) and trust badges signalling a tax-deductible, verified charity. A warm-gradient photo placeholder carries a human caption so the layout reads like a real campaign.
The signature card centres on a goal: a horizontal progress bar and a vertical thermometer animate toward a 10,000-signature target. Signing validates name and email inline, optionally adds a short comment, and respects a privacy toggle for whether the name appears publicly. On submit the counter increments, the progress animates forward, a toast confirms your signature number, and the button locks into a thank-you state.
The right column is a sticky live feed of recent signatures — colour-seeded avatars, city and time metadata, and quoted comments. New signatures slide in at the top with a fresh highlight. Share buttons copy a link or simulate social and email sharing, and a fixed donate bar keeps the primary ask in view. Everything is keyboard-usable, contrast-checked, and collapses cleanly down to ~360px.
Illustrative UI only — fictional organization, not a real charity or donation system.
