The Bottleneck of the Web
5.3.2019
Steve Souders, "JavaScript Dominates Browser CPU":
Ten years ago the network was the main bottleneck. Today, the main bottleneck is JavaScript. The amount of JavaScript on pages is growing rapidly (nearly 5x in the last 7 years). In order to keep pages rendering and feeling fast, we need to focus...
Should I Use Source Maps in Production?
1.3.2019
It's a valid question. A "source map" is a special file that connects a minified/uglified version of an asset (CSS or JavaScript) to the original authored version. Say you've got a filed called _header.scss that gets imported into global.scss which is compiled to global.css. That final CSS file...
WorldWideWeb
27.2.2019
For the 30th anniversary of the web, CERN brought nine web nerds together to recreate the very first web browser — Or a working replication of it anyway, as you use it from your web browser, inception style.
Well done, Mark Boulton, John Allsopp, Kimberly Blessing, Jeremy Keith, Remy Sharp...
Responsive Designs and CSS Custom Properties: Defining Variables and Breakpoints
25.2.2019
CSS custom properties (a.k.a. CSS variables) are becoming more and more popular. They finally reached decent browser support and are slowly making their way into various production environments. The popularity of custom properties shouldn’t come as a surprise, because they can be really helpful...

Did you see this Facebook crap?

Social Cards as a Service
19.2.2019
I love the idea of programmatically generated images. That power is close at hand these days for us front-end developers, thanks to the concept of headless browsers. Take Puppeteer, the library for controlling headless Chrome. Generating images from URLs is their default use case:
const puppeteer...
How @supports Works
18.2.2019
CSS has a neat feature that allows us to test if the browser supports a particular property or property:value combination before applying a block of styles — like how a @media query matches when, say, the width of the browser window is narrower than some specified size and then the CSS within...
Front and Rear Camera Access with JavaScript's getUserMedia()
13.2.2019
It seems like not so long ago every browser had the Flash plugin to get access to the devices media hardware to capture audio and video, with the help of these plugins, developers were able to get

Angular, Autoprefixer, IE11, and CSS Grid Walk into a Bar…
18.1.2019
I am attracted to the idea that you shouldn't care how the code you author ends up in the browser. It's already minified. It's already gzipped. It's already transmogrified (real word!) by things that polyfill it, things that convert it into code that older browsers understand, things that make...
Amazing User Agent API with userstack
17.1.2019
We do our best to design and code websites so that they look and perform the way they should regardless of device or browser, but the truth is we sometimes we need to code for specific device, browser, or crawler. Whether it’s a quick hack or a simply wanting to display different content...

Styling a Select Like It’s 2019
31.12.2018
It's rather heartwarming to know you can style a <select> in a rather cross-browser friendly way that doesn't hurt accessibility. Kudos for documenting this Scott!

Nobody is quite wrong.
17.12.2018
There are two opposing views on using non-polyfillable new web features that I find are both equally common in our industry:
Websites don't need to look the same in every browser. The concept of progressive enhancement helps with that. There are tools, even native language features, that help with...
Browser Diversity Commentary, Regarding the Edge News
6.12.2018
Still no word from the horse's mouth about the reported EdgeHTML demise, but I hear that's coming later today. The blog posts are starting to roll in about the possible impact of this though.

Even though Opera, Beaker and Brave are all doing very good...
Sayonara Edge
4.12.2018
Sounds like Edge is going to spin down EdgeHTML, the engine that powers edge, and go with Chromium. It's not entirely clear as I write whether the browser will still be called Edge or not. Opera did this same thing in 2013. We'll surely be seeing much more information about this directly from...
