The srcset attribute is an HTML property used alongside the tag to tell a browser that alternative versions of the image exist, which are optimised for different pixel sizes, and for displays that will comprise that information at different resolutions. This will save him from downloading those versions that will not be appropriate for his device on top of the superior performance of the website’s visitor experience. This also means that users who will access the content from smaller screens will use even more miniature images-than-bigger screens, resulting in improved page load and overall bandwidth consumption. Besides, it assists in responding design, as images will also appear sharper and clearer with different devices. Thus, in this case, srcset being one of the best practices in image optimisation is also a must-have for efficient fast-loading websites.
