Most countdown widgets are abandoned WordPress plugins from 2014. Ours is a single async script tag — works on WordPress, Shopify, Ghost, or any HTML page.
Search 'countdown timer HTML code' and you'll wade through dozens of jQuery snippets from 2014 that depend on libraries nobody uses anymore. The FeedPulse countdown timer HTML code is a single async script tag — no jQuery, no Moment.js, no setInterval to debug. Pass ?target=2026-12-31T23:59:59Z for any ISO-8601 timestamp and the widget renders a 4-tile display (days / hours / minutes / seconds) that ticks down in real time. The countdown timer HTML code is themeable via 7 prebuilt presets or fully overridable with your own CSS. Works in every modern browser and falls back gracefully on no-JS.
To embed countdown on website launch pages, paste the script tag into your hero section above the fold and visitors see the timer the moment the page paints. To embed countdown on website blog posts (a 'this offer ends in X hours' inline pill), use the pill layout (?layout=pill) so it fits mid-paragraph. The same snippet works to embed countdown on website Shopify storefronts (Custom HTML block in the theme customizer), Ghost articles (HTML card), Substack (raw HTML in a post), Webflow (Embed component), and plain HTML pages. No platform-specific plugin needed.
A launch countdown widget is meaningless if it shows a different end-time to different visitors depending on their browser locale. The FeedPulse launch countdown widget renders against a single source-of-truth UTC target, so a customer in Tokyo and a customer in San Francisco both see the exact same remaining time. The launch countdown widget supports preconfigured campaigns (Black Friday 2026-11-27, Christmas 2026-12-25, New Year 2027-01-01) via query string, so you don't even have to type out the date. Drop the widget, name the campaign, ship.
