Srcset

Srcset is an HTML attribute used within the <img> tag to provide a set of image sources with different sizes for different screen resolutions and device widths. This allows browsers to select the most appropriate image based on the device's screen size and resolution.

By using srcset, you ensure that users receive images that are optimized for their devices, improving page load time and user experience.

Why Srcset is important

• Responsive design: Srcset is crucial for responsive web design, ensuring images look great on devices of all sizes (from mobile phones to desktop monitors).
• Faster load times: By serving appropriately sized images, you can reduce the image file size and improve loading times, particularly for users on mobile devices or slow internet connections.
• Better SEO: Providing optimized images improves user experience, which can lead to higher engagement and lower bounce rates, positively affecting your SEO.

Example of using srcset

Here’s how you would use srcset in an <img> tag to display different images based on the viewport size:

<img src="image.jpg" 
     srcset="image-400w.jpg 400w, image-800w.jpg 800w, image-1200w.jpg 1200w"
     alt="A sample image">

Benefits of using srcset

• Optimizes image delivery: Ensures users get the right image size for their device, reducing unnecessary data usage.
• Improves performance: Smaller, optimized images load faster, enhancing the overall speed of your website.
• Enhances user experience: Providing crisp, responsive images across all devices improves how users interact with your site.

In summary, srcset is an essential HTML attribute for serving responsive, optimized images to users across different devices and screen sizes. It helps with performance, user experience, and SEO by ensuring the right image is loaded, reducing unnecessary data usage, and enhancing site speed.
