FAQ

Frequently Asked Questions

Simply copy the generated code from the customizer panel and paste it into your HTML page. First, ensure you've included jQuery 3.0+ (via CDN or local file), then include the Countdown Timer Pro CSS and JS files. Create a container element with the ID specified in the code (default is <code>#my-timer</code>), and the timer will automatically initialize when the page loads. The code is production-ready and requires no modifications.

Yes! Countdown Timer Pro fully supports multiple independent instances on the same page. Simply create multiple container elements with unique IDs (e.g., <code>#timer1</code>, <code>#timer2</code>, <code>#timer3</code>) and initialize each timer separately with its own configuration. Each timer operates independently with its own countdown, styling, and event handlers. This is perfect for showing multiple events, products, or promotions simultaneously.

For accurate, tamper-proof countdowns, use server-side timestamps. Set <code>timeSource: 'server'</code> and provide a Unix timestamp (in seconds) for the <code>endTime</code> parameter. Generate this timestamp on your server (PHP: <code>time()</code>, Node.js: <code>Math.floor(Date.now() / 1000)</code>, etc.) to ensure accuracy across different timezones and prevent client-side manipulation. This is essential for e-commerce sales and time-sensitive promotions.

You have full control over the expire behavior. Configure the <code>expireAction</code> option to: <code>'hide'</code> (timer disappears), <code>'message'</code> (display custom text), <code>'redirect'</code> (navigate to a URL), or <code>'callback'</code> (execute custom JavaScript function). You can also combine actions. The expire event fires a callback that you can use to trigger additional logic, update UI elements, send analytics events, or integrate with your backend systems.

Yes! Countdown Timer Pro is fully responsive and automatically adapts to all screen sizes. The timer uses CSS and JavaScript to maintain its aspect ratio while scaling proportionally. On mobile devices, the timer intelligently adjusts font sizes and circle thickness for optimal readability. The ResizeObserver API ensures smooth resizing when the container dimensions change, making it perfect for responsive layouts, mobile-first designs, and dynamic content areas.

Absolutely! Enable multicolor animation and provide a comma-separated list of hex color codes (e.g., <code>'#667eea, #764ba2, #f093fb'</code>). The timer will smoothly transition between these colors over time, creating a dynamic, eye-catching visual effect. You can use 2-10 colors for different animation styles. The transition speed and easing are optimized for smooth, professional animations. This feature works perfectly with all timer styles and is especially effective for premium, modern designs.

Countdown Timer Pro includes multiple premium animation options: <strong>Pulse/Glow</strong> (pulsating glow effect with adjustable intensity and speed), <strong>Gradient Wave</strong> (animated gradient that flows through circles with customizable colors), <strong>Celebration Animations</strong> (confetti and particle effects when timer expires with configurable intensity and types), and <strong>3D Effects</strong> (dynamic shadows, parallax, and optional rotation for depth). All animations are optimized for 60fps performance and can be combined for stunning visual effects.

Sound effects use the Web Audio API for high-quality audio playback. You can enable <strong>tick sounds</strong> (plays once per second during countdown) and <strong>finish sounds</strong> (plays when timer reaches zero). Both sounds are generated programmatically, so no external audio files are required. Volume is adjustable (0.0 to 1.0), and you can disable individual sounds while keeping others active. Sound effects are automatically disabled if the browser doesn't support Web Audio API.

Yes! The <strong>CTA button</strong> feature allows you to add a customizable button below (or above) the timer. You can set the button text, URL, position, colors (background, text, hover), padding, border radius, font size, and weight. The button opens links in a new tab by default and supports custom click handlers. Perfect for driving conversions, directing users to product pages, or capturing leads. The button is fully responsive and matches your timer's design aesthetic.

The customizer panel includes powerful preset management: <strong>Export</strong> your configuration as a JSON file to save and share presets, <strong>Import</strong> saved presets to quickly load previous configurations, and <strong>Share via URL</strong> to generate shareable links that automatically load your configuration. These features are perfect for team collaboration, client approvals, and reusing configurations across multiple projects. All preset data includes complete timer settings, animations, and styling options.

Use the customizer panel to adjust all visual properties in real-time. For colors, you can set the circle color (progress indicator), circle background, and text color. For fonts, choose from 8 pre-loaded families (Arial, Helvetica, Segoe UI, Georgia, Times New Roman, Courier New, System Sans, System Mono) or specify any custom font family. Adjust font weight (300-900) and label font weight independently. All changes are instantly reflected in the live preview, and the generated code includes your exact specifications.

Yes! Countdown Timer Pro provides a comprehensive event system. You can attach callbacks for: <code>onStart</code> (when timer begins), <code>onTick</code> (every second during countdown), <code>onExpire</code> (when countdown reaches zero), and <code>onReset</code> (when timer restarts). These callbacks receive the timer instance and current time values, allowing you to integrate with analytics, update other page elements, trigger notifications, or perform custom business logic. All callbacks are optional and can be combined as needed.

Auto-reset allows the timer to automatically restart after it expires. Configure <code>autoReset</code> with values like <code>'daily'</code>, <code>'hourly'</code>, or a custom interval in milliseconds. This is perfect for recurring promotions, daily deals, or countdowns that should restart automatically. The timer will seamlessly reset and continue counting, maintaining all your custom styling and configuration. This feature is ideal for e-commerce sites with rotating sales or subscription services with recurring offers.
