Implementation Methods

There are several ways to implement smooth scrolling to elements. Here are the most common approaches:

Method 1: CSS Only

        html {
        scroll-behavior: smooth;
        }
      

The simplest method - just add this to your CSS and all anchor links will scroll smoothly.

Method 2: scrollIntoView()

        // Scroll to element smoothly
        const element = document.getElementById('section-id');
        element.scrollIntoView({
        behavior: 'smooth',
        block: 'start'
        });
      

Native JavaScript method with good browser support and customization options.

Method 3: Custom Animation

        function smoothScrollTo(element) {
        const targetPosition = element.getBoundingClientRect().top;
        const startPosition = window.pageYOffset;
        const distance = targetPosition;
        const duration = 1000;
        let start = null;

        function animation(currentTime) {
        if (start === null) start = currentTime;
        const timeElapsed = currentTime - start;
        const run = ease(timeElapsed, startPosition, distance, duration);
        window.scrollTo(0, run);
        if (timeElapsed < duration) requestAnimationFrame(animation);
      }

      function ease(t, b, c, d) {
      t /= d / 2;
      if (t < 1) return c / 2 * t * t + b;
    t--;
    return -c / 2 * (t * (t - 2) - 1) + b;
    }

    requestAnimationFrame(animation);
    }
    

Full control with custom easing functions and animation timing.

Practical Examples

Here are some real-world use cases for smooth scrolling:

📱 Single Page Applications

Perfect for one-page websites with multiple sections like portfolios, landing pages, and product showcases. Users can navigate seamlessly between different sections without page reloads.

📚 Documentation Sites

Great for technical documentation and knowledge bases where users need to jump between different topics. Smooth scrolling makes navigation feel natural and intuitive.

🛒 E-commerce Sites

Useful for product pages with multiple sections like reviews, specifications, and related products. Smooth scrolling enhances the shopping experience.

Best Practices

Use scroll-margin-top to account for fixed headers
Keep animation duration between 500-1000ms for optimal UX
Test on mobile devices - touch scrolling behaves differently
Provide fallbacks for older browsers
Consider accessibility - some users prefer reduced motion
Ensure keyboard navigation still works properly

Contact Section

This is the final section of the page. You've successfully scrolled through all sections using smooth scrolling!

Notice how the navigation buttons in the header and throughout the page all use smooth scrolling to navigate between sections. The scroll animation provides a much better user experience compared to instant jumping.
