 If you know what size the image will display at, the optional `sizes` attribute helps the browser to decide the most appropriate image before waiting to reflow the entire DOM first. For example, `sizes="100vw"` means a full-width image. (Percentage values will not work here, since the browser will have to answer the question "percent of what?", which requires a full DOM reflow.)
 
-Because `srcset` is an attribute on the standard `<img>` tag, browsers that do not understand it fallback to the image specified in `src`, making this safe to use immediately. Firefox supports `srcset` now as of version 38, but Safari only has [partial support](http://caniuse.com/#feat=srcset) for resolution switching only. A [polyfill](http://scottjehl.github.io/picturefill/) is available if you want to bring this functionality to older browsers and Internet Explorer, but it is not required.

 The `<picture>` element allows a designer to explicitly specify the right image to use for different scenarios, similar to using media queries but for image tag sources. The element itself is merely a container; any number of `<source>` tags inside of `<picture>` is where all the magic happens. Finally, a required `<img>` element declares the default image to use if no other conditions are met. Browsers that do not support `<picture>` will gracefully fallback to this `<img>` tag, making this safe to use.
