What specific section or headline is this issue about?

The srcset attribute

What information was incorrect, unhelpful, or incomplete?

After an example in the srcset section, references is made to sizes, but sadly sizes hasn't been introduced or explained.

What did you expect to see?

It would be helpful to explain what sizes is used for, since it isn't a common HTML 5 attribute and even more helpful if it was contained in an example.

Do you have any supporting links, references, or citations?

No response

Do you have anything more you want to share?
