Creating long images for horizontal screens in frontend development involves several steps to ensure proper rendering and user experience. Here’s a comprehensive guide:

1. Image Dimensions:
2. Set the image width to 100% or a fixed pixel value to make it responsive.

3. Use height: 100vh or a percentage of viewport height for longer images.

4. CSS Layout:
   .horizontal–image–container {     overflow–x: hidden;     white–space: nowrap;     width: 100%;   }
   This prevents horizontal scrolling and keeps content in one line.

5. Responsive Design:

6. Use media queries for different screen orientations.

7. Example for portrait adjustment:
   @media (orientation: portrait) {       .horizontal–image {         max–width: 100%;         height: auto;       }     }

8. Horizontal Scroll Handling:

9. Apply overflow–x: hidden to the container to disable scrolling.
   html {     overflow–x: hidden;   }

10. Flexbox for Alignment:

11. Use Flexbox properties to align items horizontally.
    .horizontal–container {     display: flex;     justify–content: space–between;     width: 100%;   }

12. JavaScript for Dynamic Content:

13. Use Intersection Observer to detect when images enter the viewport and load them dynamically.
    “`
    const observer = new IntersectionObserver((entries) => {
    entries.forEach(entry => {
    if (entry.isIntersecting) {
    entry.target.src = entry.target.dataset.src;
    }
    });
    });

document.querySelectorAll(‘.lazy-image’).forEach(img => {
observer.observe(img);
});
“`

By following these steps, you can create long images that adapt well to horizontal screens, ensuring a seamless user experience across devices.
