CSS Houdini Could Change the Way We Write and Manage CSS

28.3.2019
CSS Houdini may be the most exciting development in CSS. Houdini is comprised of a number of separate APIs, each shipping to browsers separately, and some that have already shipped (here's the browser support). The Paint API is one of them. I’m very excited about it and recently started to think...

In this 15 minute tutorial we’re going to build a simple decentralized chat application which runs entirely in a web browser. All you will need is a text editor, a web browser, and a basic knowledge of how to save HTML files and open them in the browser. We’re going...

All About mailto: Links

22.3.2019
You can make a garden variety anchor link (<a>) open up a new email. Let's take a little journey into this feature. It's pretty easy to use, but as with anything web, there are lots of things to consider. The basic functionality <a href="mailto:someone@yoursite.com">Email...

Blurred Borders in CSS

20.3.2019
Say we want to target an element and just visually blur the border of it. There is no simple, single built-in web platform feature we can reach for. But we can get it done with a little CSS trickery. Here's what we're after: The desired result. Let's see how we can code this effect, how we...

The Process of Implementing A UI Design From Scratch

13.3.2019
This is a fantastic post by Ahmad Shadeed. It digs into the practical construction of a header on a website — the kind of work that many of us regularly do. It looks like it's going to be fairly easy to create the header at first, but it starts to get complicated as considerations for screen...

Downsides of Smooth Scrolling

11.3.2019
Smooth scrolling has gotten a lot easier. If you want it all the time on your page, and you are happy letting the browser deal with the duration for you, it's a single line of CSS: html { scroll-behavior: smooth; } I tried this on version 17 of this site, and it was the second most-hated thing...

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...

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...

Introduction In this article, we'll learn how to use most methods available in the nodeJS console class more effectively. To demonstrate, I'll use Chrome browser version 70

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...
