I’ve started trialling different HTML and technologies for the “simple” responsive images (i.e. not art-directed per breakpoint) used in blog articles on this site. I’m continuing to lean on Cloudinary as my free image host, CDN and format-conversion service. But at the HTML level I’ve moved from a complicated <img srcset> based approach which included many resized versions of the same image. I now use a simpler <picture> and <source> based pattern that keeps the number of images and breakpoints low, leaning instead into the performance gains offered by the newer image formats avif and webp.

Recently I’ve noticed some developers recommending using the CSS aspect-ratio property directly on images. My understanding of aspect-ratio was that it’s not so much intended for elements like img which already have an intrinsic aspect ratio, but rather for the likes of div which do not. Furthermore, when the goal is to prevent the layout shift that can occur after an image loads we should supply our images with width and height HTML attributes rather than using CSS.

In this timely post, Jake helpfully explains how width and height attributes are used by CSS as presentation hints to automatically set an aspect-ratio that will also, in cases where the attributes were set wrongly, fall back to the image’s intrinsic aspect ratio. Therefore, concentrating on HTML alone is ideal for our content images. My previous approach seems sound but I now know a little more about why.

Some colleagues at work have recently been asking interesting questions about “good/appropriate alternative text for images”. I definitely reckon it’s a topic worth revisiting because it feels like the landscape has changed a bit on this front over the years.

Jeremy Keith’s new course for Google’s web.dev learning platform is fantastic and covers a variety of aspects of responsive design including layout (macro and micro), images, icons and typography.

In modern web development there are a myriad ways to present an image on a web page and it can often feel pretty baffling. In this series I step through the options, moving from basic to flexible images; then from modern responsive images to the new CSS for fitting different sized images into a common shape. By the end I’ll arrive at a flexible, modern boilerplate for images.

Chris Coyier takes the new CSS aspect-ratio property for a spin and tests how it works in different scenarios.

Here’s a lovely intrinsically responsive (no media queries) photo gallery solution from Stephanie Eckles. It can accommodate differently sized images and achieves its layout by a combination of flexbox features (flex-wrap, flex-basis) and by applying object-fit: cover to photos to make them fully cover their parent list items.

While bookmarking the mastery.games article yesterday, I started getting the feeling that something was awfully familiar. It was! I’ve seen this layout before – from Tyler Sticka back in 2017 to be precise – but failed to bookmark it at the time.

This episode explores creating website heroes - aka “headers” - with one of my favorite ways to use CSS grid layout: by turning it into a canvas.

Here’s a beautiful, magazine style website design for digital publication Bustle. The typography, use of whitespace, responsive layout, menu pattern, colour palette and imagery are all on point!

Modern CSS Solutions for Old CSS Problems

Here’s how to improve performance and prevent layout jank when browsers load responsive images.

Now that we have the HTML attribute loading we can set loading="lazy" on our website’s media, and the loading of non-critical, below-the-fold media will be deferred until the user scrolls to them.
