Filtered Flexbox: A Dynamic Image Gallery

javascript / galleries

Estimated reading time: 3 minutes

While I’ve shown filtered responsive image galleries in the past, they don’t have the dynamism that some designers desire. Of course, it’s easy to take “dynamism” too far, into what I refer to as “swooshy-swooshy” UI, with massive dependencies on frameworks and plugins and everything on the page whirling about in confusion.

This gallery code seeks balance: a straightforward UI coupled with non-disorienting animation. Along the way, we can learn a few things about making progressively enhanced UI elements.

Responsive Images For Retina: Using HTML5’s srcset

mobile / responsive design

Estimated reading time: 5 minutes

This past Thursday saw the release of Apple’s new “Retina”-screen iMac, making it official: we are now in the world of desktop high-DPI screens. This makes the job of designers and developers doubly difficult, expanding an image quality problem that was previously confined to mobile devices and high-end laptops to one that will soon reach computers everywhere.

Thankfully, HTML5 now has a solution. But before looking at that, we should have a better understanding of the Retina problem.

An SVG Analog Clock In 6 Lines of JavaScript

javascript / time

Estimated reading time: 2 minutes, 45 seconds

Compared to the JavaScript digital clock I demonstrated in the previous article, this SVG analog clock uses fewer lines of code, and has the advantage of being infinitely scalable.

I’ve always admired the elegance of the code, expressed earlier by Felix Gnass. First, there’s my version of the , which consists of just four elements: the dial, and three rectangular hands (hours, minutes, and seconds):
