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...
Browser Rendering Optimizations for Frontend Development

We live in an age where the importance of delivering web services at optimal speed can't be overemphasized. As the payload transmitted by web applications increase, developers must adopt best pract

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!
See the Pen Styled <select&rt; by Chris Coyier (@chriscoyier) on CodePen.

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.
Andre Garzia: While we Blink, we loose the Web:
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...
Get Viewport Lines and Columns in CodeMirror
27.11.2018
CodeMirror is an amazing utility for presenting code in a browser environment. Syntax highlighting, widgets, and a number of advanced functions make it a unique, useful tool. When using CodeMirror inside the Firefox DevTools debugger, I found that adding hundreds of column breakpoint widgets...
Stuff you can do with CSS pointer events
27.7.2018
Martijn Cuppens (the same fella with the very weird div!) has some more irresistible CSS trickery. Three of the examples are about making a child element trigger an event on a parent element (almost like the magic that is :focus-within).
Here's how I reasoned it out to myself:
You know how if...
Did you know that style and script tags can be set to display: block?
25.7.2018
The other night, Amit Patel mentioned that you can set script tags in HTML to display: block with CSS and then edit that code inline with the contentEditable attribute. This means that you can then see it all update live in the browser as you type. Shortly after, Marius Gundersen replied that...

I remember seeing this Tom Dale tweet a while back. It's literally about the browser's ability to look at the HTML of the document you're looking at as it first arrived. Now the tweet is stirring up a new round of conversation.
Jonathan Snook has kind of a baby bear take:
We have the ability...
8 Digit Hex Colors
16.7.2018
One of the most requested capabilities in my early days of web development was the ability to set opacity on elements and even PNG images without the need for browser-specific CSS or hacks. Eventually we got native opacity support and even enjoyed rgba(), the ability to cite an opacity level with...
