How to Crop Videos

9.8.2019
During a recent episode of the Script and Style podcast, I had noticed that the video recording had showed a bit of our internal chat that wasn’t necessary for our viewers to see. While there’s nothing wrong with giving viewers a peek into the show preparation, presenting the best...

SSCCE

6.8.2019
You know what a "reduced test case" is, right? We've talked about it here. I imagine the concept is useful in many walks of life, but in the world of front-end development, you can think of it like: A reduced test case is a demo/example page you create which reproduces the problem you are having...

then on Objects

5.8.2019
Promises were a revelation in JavaScript development, allowing us to enjoy async processing and avoid callback hell. Many new APIs like Battery API, Cache API, and others use the promise API. One fact you may not know is that you can add a then method to any object to make it Promise-like!...

A More Accessible Portals Demo

31.7.2019
The point of the <portal> element (behind a flag in Chrome Canary) is that you can preload another whole page (like <iframe>), but then have APIs to animate it to the current page. So "Single Page App"-like functionality (SPA), but natively. I think that's pretty cool. I'm a fan...

CSS prefers-reduced-motion Media Query

30.7.2019
When I started in the web development industry, media queries were limited — screen and print were the two media queries I was most often using. More than a decade later, media queries have advanced to various screen units, feature checking, and even color scheme preference. I’ve been...

Creating Dynamic Routes in a Nuxt Application

30.7.2019
In this post, we’ll be using an ecommerce store demo I built and deployed to Netlify to show how we can make dynamic routes for incoming data. It’s a fairly common use-case: you get data from an API, and you either don’t know exactly what that data might be, there’s a lot of it, or it might change....

Optional Chaining

29.7.2019
For all of the improvements that the JavaScript language has added over the past few years, like the spread operator, default argument values, and arrow functions, there are still a few features I’d love to see implemented. On such feature is optional chaining. Optional chaining allows...

JavaScript Proxy with Storage

26.7.2019
The JavaScript Proxy API provides a wealth of “magic” within JavaScript, allowing you to use any object as sort of an alias that allows a wall of validation, formatting, and error throwing. Did you know that you could also employ the Proxy API as an abstraction to different types...

Grab a .DEV Domain from Hover! (Sponsored)

19.7.2019
I can say that the biggest and best changes in my professional life came from starting this blog — it was the springboard for conference speaking, open source, and joining Mozilla. I’ve always urged ever developer to have a blog to showcase talent, explore new technology, and to network. What’s...

Detect Cryptocurrency by Wallet Address

16.7.2019
I’ve always been a massive advocate of cryptocurrency. I love the technology, the ease of use, and the freedom that cryptocurrencies bring to the world. Despite my love of crypto, I know that adoption will take a long time and that the state of crypto is not friendly to new adopters. One scary part...

The sixth edition of our creative web experiments roundup that collects the most interesting demos from around the web. Awesome Demos Roundup #6 was written by Mary Lou and published on Codrops

CSS Gradient Text

15.7.2019
Web developers know the fight we’ve all had to improve fonts on the web. Whether it be load time, odd strategies for using custom fonts (Cufon, anyone?), or just finding the right font itself, beautifying text on the web has never come easy. That got me thinking about fonts and CSS gradients, since...

Set Video Playback Speed with JavaScript

2.7.2019
I love that media has moved from custom plugins (Flash…gross) to basic HTML <video> and <audio> elements. Treating these media sources as just another element allows us to use CSS filters to adjust display, for example. The less we need to do with ffmpeg or plugins, the better. I’ve been...

Fix Touch Bar Volume Buttons

30.6.2019
The touch bar on MacBooks has been a source of controversy since the beginning. Many mourned the loss of the escape key, while others refused to buy a new laptop to avoid the touch bar completely. I’ve not had many issues with the touch bar but mostly because I don’t really use it. One necessary...

How to Debug Remote Browsers

27.6.2019
It’s super frustrating when bugs pop up only in a remote browser. Something about that user, that device, or that environment is different, but I don’t know what! And of course, I can’t recreate it on my local development machine. The team at TrackJS came up with a cool way...

CSS :focus-within

25.6.2019
Using :hover to display additional information or elements is a very useful technique but a big drawback to using the hover pseudo-class is that they are usually not accessibility-friendly. Not everyone uses a mouse and some users have visual impairments, so they rely on screen readers or...

Checkout the Last Public Revision with Mercurial

19.6.2019
I’ve always preferred git over Mercurial (hg) because the feature branch workflow makes organizing code and working off of master very easy. You don’t get that with vanilla mercurial — instead, commits can just sort of apply on top of each other, without much organization....

How to Detect Text in Images

11.6.2019
Images are a great way to communicate without text but oftentimes images are used/abused to spread text within social media and advertisements. Text in images also presents an accessibility issue. The truth is that it’s important, for any number of reasons, to be able to detect text in image...
