Keep Math in the CSS

12.12.2018
There is a sentiment that leaving math calculations in your CSS is a good idea that I agree with. This is for math that you could calculate at authoring time, but specifically chose not to. For instance, if you needed a 7-column float-based grid (don't ask), it's cleaner and more intuitive: .col...

Prototypes and production

11.12.2018
There’s an interesting distinction that Jeremy Keith defines between prototype code and production code in this post and I’ve been thinking about it all week: ...every so often, we use the materials of front-end development—HTML, CSS, and JavaScript—to produce something that isn’t intended...

JavaScript waitForever

10.12.2018
Writing mochitests for new features in DevTools can be difficult and time-consuming.  There are so many elements interacting in an async manner that I oftentimes find myself using the debugger to debug the debugger!  In the case where it’s unclear what interaction isn’t working...

An Introduction and Guide to the CSS Object Model (CSSOM)

10.12.2018
If you've been writing JavaScript for some time now, it's almost certain you've written some scripts dealing with the Document Object Model (DOM).

CSS Selectors are Conditional Statements

6.12.2018
foo { } Programmatically, is: if (element has a class name of "foo") { } Descendent selectors are && logic and commas are ||. It just gets more complicated from there, with things like combinators and pseudo selectors. Just look at all the ways styles can cascade. Jeremy Keith: If...

Nesting Components in Figma

30.11.2018
For the past couple of weeks, I’ve been building our UI Kit at Gusto, where I work, and this is a Figma document that contains all of our design patterns and components so that designers on our team can hop in, go shopping for a component that they need, and then get back to working on the problem...

Turn Bluetooth On and Off from Command Line on macOS

6.11.2018
Bluetooth has been a revelation in wireless technology: wireless mice, headphones, streaming devices, and a variety of home and office environments.  It goes without saying that wireless peripherals are so much easier to manage than wired counterparts, especially mice, that I usually have...

Mercurial: Mass Add and Remove All Files

29.10.2018
While I much prefer git and the GitHub workflow, Firefox’s codebase (mozilla-central) is store in a mercurial repository.  There are tools that wrap mercurial so you can use a git-like interface, like git-cinnabar, but my philosophy is to learn the root tool so that I know what’s going...

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...

Remember "cybersecurity"? Mysterious hooded computer guys doing mysterious hooded computer guy .. things! Who knows what kind of naughty digital mischief they might be up to? Unfortunately, we now live in a world where this kind of digital mischief is literally rewriting the world's...

The peculiar magic of flexbox and auto margins

27.7.2018
In front-end development, there are often times when I know that I don’t know something. I might know enough to know what CSS to search for, but I have absolutely no idea how to use it or what the right syntax is. Somehow, in my head, there appears to be a filing cabinet that’s entirely empty,...

Create the Google Button Effect with CSS

27.7.2018
I always found Google’s branding simple but grew to realize that was the beauty in their design; there’s something about “just enough” that is the perfect balance between bland and over the top.  GMail’s design grew old over the years and Google just got around...

Finite State Machines with React

24.7.2018
As JavaScript applications on the web have grown more complex, so too has the complexity of dealing with state in those applications — state being the aggregate of all the data that an application needs to perform its function. Over the last several years, there has been a ton of great...
