Consider the following markup. Is it valid? If not, can you explain why?
<figure>
<picture>
<source media="(min-width: 40em)"
srcset="large.jpg 1024w, medium.jpg 640w, small.jpg 320y">
<img src="medium.jpg" alt="London by night">
</picture>
<figcaption>A landscape of London by night</figcaption>
</figure>Answer:
The markup uses the relatively new picture element. The code is all valid apart from the last image specified in the srcset attribute. 320y is not a valid value, and the y should be replaced with a w.
