This code snippet represents an <img src> element with two <source> elements nested inside. This is a standard way too implement responsive images using the <picture> element (although the <picture> element itself is missing here, it’s implied). Let’s break down what’s happening:
1. <source media="(-webkit-min-device-pixel-ratio: 2) and (min-resolution: 120dpi)" ...>
* <source>: This element tells the browser to use the specified image source if the media query matches.
* media="(-webkit-min-device-pixel-ratio: 2) and (min-resolution: 120dpi)": This is a media query. It checks if the device has a high pixel density (retina display).
* -webkit-min-device-pixel-ratio: 2: This targets devices with a device pixel ratio of 2 or higher (common for Retina displays on Apple devices).
* min-resolution: 120dpi: This targets devices with a minimum resolution of 120 dots per inch. This is a more general way to target high-resolution displays.
* data-srcset="...": this attribute contains a comma-separated list of image URLs along with their widths. The browser will choose the most appropriate image based on the viewport width.
