Undefined: The Third Boolean Value
5.4.2019
I wanted to implement a notification message in one of my projects, similar to what you’d see in Google Docs while a document is saving. In other words, a message shows up indicating that the document is saving every time a change is made. Then, once the changes are saved, the message becomes: “All...
CSS Houdini Could Change the Way We Write and Manage CSS
28.3.2019
CSS Houdini may be the most exciting development in CSS. Houdini is comprised of a number of separate APIs, each shipping to browsers separately, and some that have already shipped (here's the browser support). The Paint API is one of them. I’m very excited about it and recently started to think...

From the CMC editorial desk: One of the things we’ve always wanted to explore is what mass adoption of blockchain technology looks like. Here we have some examples of how it will change the face of the communication industry in […]

Using <details> for Menus and Dialogs is an Interesting Idea
21.3.2019
One of the most empowering things you can learn as a new front-end developer who is starting to learn JavaScript is to change classes. If you can change classes, you can use your CSS skills to control a lot on a page. Toggle a class to one thing, style it this way, toggle to another class...
Accessibility is not a “React Problem”
11.3.2019
Leslie Cohn-Wein's main point:
While [lots of divs, inline styles, focus management problems] are valid concerns, it should be noted that nothing in React prevents us from building accessible web apps.
True. I'm quite capable (and sadly, guilty) of building inaccessible interfaces with React...
Do CSS Custom Properties Beat Sass Loops?
2.3.2019
I reckon that a lot of our uses of Sass maps can be replaced with CSS Custom properties – but hear me out for a sec.
When designing components we often need to use the same structure of a component but change its background or text color based on a theme. For example, in an alert, we might need...
Control Icons with Font Size
27.2.2019
Here’s a nifty trick from Andy Bell that now seems a little obvious in hindsight: if you set an SVG to have a width and height of 1em then you can change the size of it with the font-size property.
Try and change the font-size on the body element below to see the icon scale with the text:

The Many Ways to Change an SVG Fill on Hover (and When to Use Them)
31.1.2019
SVG is a great format for icons. Vector formats look crisp and razor sharp, no matter the size or device — and we get tons of design control when using them inline.
SVG also gives us another powerful feature: the ability to manipulate their properties with CSS. As a result, we can make quick...
How to Change Animated GIF Speed
29.1.2019
Comedians would tell you that timing is the most important part of any joke. The same could be said about animated GIFs; whether they’re used as a meme or to illustrate a process, the speed of an animated GIF can effect its effectiveness. With that idea in mind, I set about trying to figure...
prefers-color-scheme: CSS Media Query
28.1.2019
One device and app feature I’ve come to appreciate is the ability to change between light and dark modes. If you’ve ever done late night coding or reading, you know how amazing a dark theme can be for preventing eye strain and the headaches that result. macOS recently implemented...
In Defense of Utility-First CSS
15.1.2019
A rather full-throated argument (or rather, response to arguments against) utility (atomic) CSS from Sarah Dayan. I wondered recently if redesigns were potentially a weakness of these types of systems (an awful lot of tearing down classes) which Sarah acknowledges and recommends more abstraction...
Converting Color Spaces in JavaScript
10.1.2019
A challenge I faced in building an image "emojifier" was that I needed to change the color spaces of values obtained using getImageData() from RGB to HSL. I used arrays of emojis arranged by brightness and saturation, and they were HSL-based for the best matches of average pixel colors with...
How to Change the WordPress Admin Login Logo
2.1.2019
There are numerous content management systems that thrive these days but none are as prolific as WordPress. Every client wants the ability to change their website at a moment’s notice and they want to do it themselves, and again, WordPress is the best fit for that. You fit the client with...
How to Change the WordPress Media Upload Directory
2.1.2019
One thing I’ve always missed about the “old” way of web development was the simplicity of FTP. No deploy scripts, no fuss: simple drag and drop of files and the files are there. I’ve used FTP for assets on this blog for over a decade but I’m finally ready to be lazy...
Goals for 2019
31.12.2018
Every turn of the year is a new opportunity to start over, set goals, and renew optimism that time can heal wounds and drive us to change and achieve. I did really well with my 2018 goals: I started a fun podcast with TrackJS’ Todd Gardener I found my passion again by joining Mozilla’s...
Change Mac Brightness from Command Line
24.10.2018
Earlier this week I posted about how you can modify your Mac’s volume from command line. Little command line scripts make me smile because I spend so much of my day in command line, and automation can be the key to productivity. I next thought about modifying brightness from command line...
Find and Change Default App for File Type from Command Line
23.10.2018
There are few things more frustrating to any computer user than files opening in an unwanted application. Sure you can use the Open menu item in the desired application but we all just want to double-click a file and see it open in the application we expect. I recently got to thinking about this...
Change System Volume from Command Line on Mac OS
15.10.2018
Oftentimes the awesome GUI applications we love are simply gloss over a command line functionality. While I do love a visual app, it’s always good to know how to do things from command line, if only for the sake of automation. I’ve covered loads of command line secrets, most notably...
