Animate SVG Path Changes in CSS
20.2.2020
Every once in a while I'm motivated to attempt to draw some shapes with <path>, the all-powerful drawing syntax of SVG. I only understand a fragment of what it all can do, but I know enough to be dangerous. All the straight-line syntax commands (like L) are pretty straightforward and I find...
Add Background Colors to SVGs Using the “rect” Element
20.2.2020
The advantages of using SVGs in web development are well known. SVGs are small in size, can be made quite accessible, are scalable while maintaining their quality, and can be animated. Still, there is a learning curve. Things, like the syntax of SVG, can be a little tricky and having to hand-alter...
Lazy Object Initialization
17.2.2020
The Firefox DevTools underlying code, which is written with JavaScript and HTML, is a complex application. Due to the complexity and amount of work going on, the DevTools team has done everything they can to load as little as possible. Furthermore the team has a system of lazily importing...

Building an Images Gallery using PixiJS and WebGL
12.2.2020
Sometimes, we have to go a little further than HTML, CSS and JavaScript to create the UI we need, and instead use other resources, like SVG, WebGL, canvas and others.
For example, the most amazing effects can be created with WebGL, because...
Override window.alert
11.2.2020
For years the only bit of feedback web developers could get was via alert("{str}") calls. These days we have the web console but, in rare cases, we don’t have a console and alert calls are our only window into a value at a given time. One problem: if an alert sneaks into production code, your...
Awesome Forward & Reverse Geocoding API: positionstack (Sponsored)
6.2.2020
One awesome web functionality we take for granted is geolocation. Based on geolocation data, we can get someone to their destination, provide them suggestions based on their location, and so on. One downside of native geolocation, especially in the browser, is that it’s limited in both input...
Git Branch Autocompletion
4.2.2020
Naming git branches is something most of us have down to a science. My branch naming pattern is usually {issue number}-short-feature-description, though many developers prefer to lead with the description and end with the issue. Regardless of the pattern you use, having a feature like autocomplete...

Woodworking SVG (and Other Real Life Encounters)
27.1.2020
Eric Meyer does his woodworking math in SVG.
I’ve been hand-coding SVG schematics to figure out how thing should go together, and as a by-product, guide me in both material buying and wood cutting.
This might sound hugely bespoke and artisanally overdone, but they’re not that complicated, and...
Going Beyond Automatic SVG Compression With the “use” Element
27.1.2020
If you draw your own SVG files or if you download them from the internet, tools like this SVG-Editor or SVGOMG are your friends. Compressing the files with those tools takes only few seconds and reduces your file size a lot. But if you need to use your SVG inline to animate or interact with...
Simple Image Placeholders with SVG
27.1.2020
A little open-source utility from Tyler Sticka that returns a data URL of an SVG to use as an image placeholder as needed.
I like the idea of self-running utilities like that, rather than depending on some third-party service, like placekitten or whatever. Not that I'd advocate for feature...
What’s the Difference Between Width/Height in CSS and Width/Height HTML attributes?
24.1.2020
Some HTML elements accept width and height as attributes. Some do not. For example:
<!-- valid, works, is a good idea --<img width="500" height="400" src="..." alt="..."<iframe width="600" height="400" src="..."</iframe<svg width="20" height="20"</svg<!-- not valid...

A Trick That Makes Drawing SVG Lines Way Easier
14.1.2020
When drawing lines with SVG, you often have a <path> element with a stroke. You set a stroke-dasharray that is as long as the path itself, as well as a stroke-offset that extends so far that you that it's initially hidden. Then you animate the stroke-offset back to 0 so you can watch...
Animate Text on Scroll
13.1.2020
We covered the idea of animating curved text not long ago when a fun New York Times article came out. All I did was peek into how they did it and extract the relevant parts to a more isolated demo.
That demo is here:

Fantastic Flight API with aviationstack (Sponsored)
9.1.2020
I didn’t fly until I was 25 years of age — I was hopeless in knowing I had to be there early, the process of security, and the whole gate structure. Now that I’ve flown dozens of times for Mozilla, I feel much more comfortable with the process of flying, but feel less comfortable...
Duplicated Argument Names
6.1.2020
Oftentimes we override or monkey patch functions and, in many cases, there are arguments we don’t care too much about. A common practice for those arguments is using _ for argument names — it’s a generally accepted and known practice for “this isn’t important”....
Validate CSP from Command Line
2.1.2020
The content security policy spec has been an amazing front-end security tool to help prevent XSS and other types of attacks. I’d go as far to say that every site should implement as specific CSP as possible. If you aren’t familiar with CSPs, here’s a quick example:...
