Apple unveiled an expanded version of its San Francisco system font at WWDC 2022. Then, last month, Jim Nielsen zeroed in on the font’s variations, explaining how the font provides a spectrum of variations based on the width and weight. It’s a remarkable read if you haven’t checked it. With all of these great new […]
CSS :out-of-range
One aspect of web development I’ve always loathed was working with forms. Form elements have been traditionally difficult to style due to OS and browser differences, and validation can be a nightmare. Luckily the native HTML APIs added methods for improving the form validation situation. With input[type=number] elements, you can add min and max attributes. […]
How to Reverse an Animated GIF
Modifying visual media via code has always been a fascination of mine. Probably because I’m not a designer and I tend to stick to what I’m good at. One visual effect I love is seeing video reversed — it provides a sometimes hilarious perspective on a given event. Take this reversed water effect for example: […]
CSS :optional
A decade ago HTML and CSS added the ability to, at least signal, validation of form fields. The required attribute helped inform users which fields were required, while pattern allowed developers to provide a regular expression to match against an <input>‘s value. Targeting required fields and validation values with just CSS and HTML was very […]
CSS :has
For as long as developers have written CSS code, we’ve been desperate to have a method to allow styling a parent element based child characteristics. That’s not been possible until now. CSS has introduced the :has pseudo-class which allows styling a parent based on a relative CSS selector! Let’s have a look at a few […]

The more you accept for input, and the more you automate, the better end output you can offer. Filestack’s workflows allow developers to define automated tasks using a their specialized UI. With no coding required, it’s easy […]
Specify Node Versions with .nvmrc
I’ve heavily promoted nvm, a Node.js version manager, over the years. Having a tool to manage multiple versions of a language interpreter has been so useful, especially due to the complexity of Node.js package management. One tip I like to give new developers is adding a .nvmrc file to their repositories. The file contents is […]
Input valueAsNumber
Every once in a while I learn about a JavaScript property that I wish I had known about years earlier — valueAsNumber is one of them. The valueAsNumber provides the value of an input[type=number] as a Number type, instead of the traditional string representation when you get the value: /* Assuming an <input type=”number” value=”1.234″ […]
Removing jQuery from GOV.UK | CSS-Tricks
The GOV.UK team recently published “How and why we removed jQuery from GOV.UK“. This was an insightful look at how an organization can assess its tooling and whether something is still the best tool for the job. This is not a nudge to strip libraries out of your current project right now! Many of us […]
JavaScript Event.defaultPrevented
Whether you started with the old on_____ property or addEventListener, you know that events drive user experiences in modern JavaScript. If you’ve worked with events, you know that preventDefault() and stopPropagation() are frequently used to handle events. One thing you probably didn’t know: there’s a defaultPrevented proptery on events! Consider the following block of code: […]
