If we all have the capability to solve problems, to communicate to others, and to make decisions toward a goal, it seems we all have the ability to design. What then, does it mean to be a designer?
It’s one thing to understand how to do something and another to actually do it. For the last few weeks I’ve been talking about responsive images, specifically the srcset attribute, the picture element, and the image-set() value on the background-image property. Along the way I promised a demo, which I’m presenting today.
What makes for a high resolution image? Is it the pixels per inch (ppi)? Is it the dots per inch (dpi)? What distinguishes an image as @1x, @2x, or @3x? If we’re going to create pixel dense images for high resolution devices, it probably makes sense to understand a little about what is a high resolution image.
