Double Touch & Penalty Breaks in Football – Explained

This is an HTML element designed for responsive images. Let’s break down what it does:

Purpose:

The element allows you to provide multiple image sources for different screen sizes, resolutions, and even image formats. The browser will choose the most appropriate source based on the user’s device and settings. This is crucial for:

Performance: Serving smaller images to smaller screens reduces download size and improves page load time.
Responsiveness: Adapting images to different screen sizes ensures they look good on all devices.
Art direction: you can even use different crops or compositions of the same image for different screen sizes. Modern Formats: Using modern image formats like WebP for browsers that support them, while falling back to older formats like JPEG for compatibility.

Breakdown of the Code:

1. : The container element. The class="smart-image" is likely used for styling or JavaScript manipulation.

1. elements: These elements define the different image sources. Each element has the following attributes:

srcset: Specifies the URL(s) of the image file(s) and their corresponding width descriptors. For exmaple:
https://s0.rbk.ru/v6toppics/resized/640xH/media/img/5/71/347489750879715.webp 640w means “use this WebP image, which is 640 pixels wide.”
type: Specifies the MIME type of the image (e.g., image/webp, image/jpeg). This helps the browser determine if it can decode the image.
media: A media query that specifies the conditions under which the srcset should be used. For example:
(max-width: 320px): Use this source if the screen width is 320 pixels or less.
(-webkit-min-device-pixel-ratio: 2), (min-resolution: 192dpi): Use this source if the device has a high-resolution display (Retina display or similar). This is for serving higher-resolution images to devices that can display them.

How it Works:

The browser evaluates the media queries in order. The first element whose media query matches the current device’s characteristics is selected. The browser then loads the image specified in the srcset attribute of that element.Specific Examples from the Code:

For screens 320px wide or less:

If the device has a high-resolution display (pixel ratio of 2 or higher, or a resolution of 192dpi or higher), the browser will try to load:
https://s0.rbk.ru/v6toppics/resized/640xH/media/img/5/71/347489750879715.webp (WebP version)
If the browser doesn’t support webp, it will fall back to:
https://s0.rbk.ru/v6toppics/resized/640xH/media/img/5/71/347489750879715.jpeg (JPEG version)
If the device has a normal resolution display, the browser will try to load:
https://s0.rbk.ru/v6toppics/resized/320xH/media/img/5/71/347489750879715.webp (WebP version)
If the browser doesn’t support WebP, it will fall back to:
https://s0.rbk.ru/v6toppics/resized/320xH/media/img/5/71/347489750879715.jpeg (JPEG version)

For screens 400px wide or less:

If the device has a high-resolution display (pixel ratio of 2 or higher, or a resolution of 192dpi or higher), the browser will try to load:
https://s0.rbk.ru/v6toppics/resized/800xH/media/img/5/71/347489750879715.webp (webp version)
If the browser doesn’t support WebP, it will fall back to:
https://s0.rbk.ru/v6toppics/resized/800xH/media/img/5/71/347489750879715.jpeg (JPEG version)

Key Takeaways:

the element is a powerful tool for responsive images.
srcset defines the image URLs and their widths. media queries control which source is selected based on device characteristics. type specifies the image format.
The browser chooses the first matching source.

The code snippet is incomplete. A element should* always contain an element as a fallback. The element is used if none of the elements match, or if the browser doesn’t support the element at all.It would typically look something like this:
