How to Cancel a Fetch Request
17.3.2020
JavaScript promises have always been a major win for the language — they’ve led to a revolution of asynchronous coding that has vastly improved performance on the web. One shortcoming of native promises is that there’s no true way to cancel a fetch…until now. A...
How to Simulate Long HTTP Requests

It happens less frequently these days but there are times when we need to accommodate for a HTTP request timing out. The service could be down, under heavy traffic, or just poorly coded, or any host of other issues. Whenever I need to simulate a long HTTP request, I use a bit of PHP...

4.3.2020
Tartan is a patterned cloth that’s typically associated with Scotland, particularly their fashionable kilts. On tartanify.com, we gathered over 5,000 tartan patterns (as SVG and PNG files), taking care to filter out any that have explicit usage restrictions.

Unfortunately, clip-path: path() is Still a No-Go
2.3.2020
I was extremely excited when I first heard that clip-path: path() was coming to Firefox. Just imagine being able to easily code a breathing box like the one below with just one HTML element and very little CSS without needing SVG or a huge list of points inside the polygon function!

Selectors Explained
2.3.2020

Here's what I wrote:
.site-footer__nav a:hover svg ellipse:first-child { }
At the end of it, I honestly couldn't...

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...

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.

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...
