A look at how the website for An Event Apart is using the picture and Picturefill …featuring Jessica as the cover girl.
Addy takes a deep dive into making sure your images are performant. There’s a lot to cover here—that’s why I ended up splitting it in two for the responsive design course: one module on responsive images and one on the picture element.
Chris has put together one of his indispensable deep dives, this time into responsive images. I can see myself referring back to this when I need to be reminded of the syntax of srcset and sizes.
A nice succint explanation of using the srcset and sizes attributes on the img element—remember, you probably don’t need picture and source elements if your use case is swapping out different sized versions of the same image.
One caveat thought: you do need to know the dimensions of the images. If you’re dealing with unknown or user-generated photos, that can be an issue.
A great primer on using srcset and picture. I think I’ll be referring back to this a lot.
Following on from that post of Jason’s I linked to, Chris also emphasises that, for most use cases, you probably only need to use srcset (and maybe sizes), but not the picture element with explicit sources.
It’s really, really great that people are writing about this, because it can be quite a confusing topic to wrap your head around at first.
