Responsive Web Design Best Practices

Responsive design turns 8 this year, and to celebrate, we asked experts from across the web industry a simple question: what does responsive design mean to you and your work, in 2018?

I’m fascinated by their answers. As many state, the technical aspects of responsive design – flexible grids, flexible media, and media queries – are more-or-less well understood, eight years in. But those simple-sounding ideas about CSS are still having far-reaching effects, which extend far beyond code. Below, you’ll read about responsive design’s impact on how individuals, teams, and entire organizations work and think. How should we model our content, now that it is responsively adapting to fit new and different contexts? How in the heck should we be prototyping and testing responsive designs? How can our teams and workflows be structured to better accomplish this new kind of work?

Responsive Images Guide Part 3: Variable Image Encoding

Welcome to the latest edition of the Responsive Images Guide!

In part 1, I laid out the big idea: a responsive image is a variable image – which adjusts itself to fit variable contexts.

In part 2, we looked at the most common way that an image can do exactly that: scaling itself up and down to fit viewports of different sizes and screens with different densities.

Responsive Images Guide, Part 1: What does it mean for an image to be “responsive”?

“Responsive.” Where did that term come from, anyways?

In his sea-changing essay, Responsive Web Design, Ethan Marcotte explained:

Recently, an emergent discipline called “responsive architecture” has begun asking how physical spaces can respond to the presence of people passing through them. Through a combination of embedded robotics and tensile materials, architects are experimenting with art installations and wall structures that bend, flex, and expand as crowds approach them. … rather than creating immutable, unchanging spaces … inhabitant and structure can—and should—mutually influence each other.

Using smart-cropping for automatic art direction

Note: this article was originally published in Smashing Magazine.

Four years ago, Jason Grigsby asked a surprisingly difficult question: How do you pick responsive images breakpoints? A year later, he had an answer: ideally, we’d set responsive image performance budgets to achieve “sensible jumps in file size”. Cloudinary built a tool that implemented this idea, and the response from the community was universal: “Great! Now – what else can it do?” Today, we have an answer: art direction!

An interview with Jason Grigsby about Responsive Images

In the conclusion of this three-part interview the Jason Grigsby, we examine what the future may hold for images on the web. Previously: Part 1, Part 2.

EP: I want to go back to the idea that we started with, that images are fundamentally complicated; that they’ll always present us with problems. What do you think we are going to be working on and talking about in five-to-10 years with regard to images?
