Good point. As long as the device is using a browser that support srcset then you're good to go. With most polyfills/shims, eventually the browser's capabilities catch up with what we want.<br />

I am using CSS media queries to change my background images for retina screens.<br />
<br />
I have a image which stretches the full width on the screen so if I allowed for large screen sizes with a pixel resolution of say 2500px it would mean my retina image width resolution would be 5000px. Even with reducing the quality and compression this creates a big file.<br />
<br />
My question is what is the largest image size you should allow for? Any advice on this appreciated.

Cascading Style Sheets (CSS) is a language used for describing the look and formatting of a document written in a markup language. Usually used to change web pages and user interfaces written in HTML, it can also be applied to any kind of XML document. CSS is designed primarily to distinguish the content of a document from its presentation.

HTML (HyperText Markup Language) is the main markup language for creating web pages and other information to be displayed in a web browser, providing both the structure and content for what is sent from a web server through the use of tags. The current implementation of the HTML specification is HTML5.

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.
