Edge Goes Chromium: What Does it Mean for Front-End Developers?

11.4.2019
In December 2018, Microsoft announced that Edge would adopt Chromium, the open source project that powers Google Chrome. Many within the industry reacted with sadness at the loss of browser diversity. Personally, I was jubilant. An official release date has yet to be announced, but it will be...

Get a CSS Custom Property Value with JavaScript

11.4.2019
Here’s a neat trick from Andy Bell where he uses CSS Custom Properties to check if a particular CSS feature is supported by using JavaScript. Basically, he's using the ability CSS has to check for browser support on a particular property, setting a custom property that returns a value of either...

Using a Mixin to Take the Math out of Responsive Font Sizes

9.4.2019
Responsive Font Size (RFS) is an engine that automatically calculates and updates the font-size property on elements based on the dimensions of the browser viewport. If you’re thinking that sounds familiar, that’s because there is a slew of tools out there that offer various approaches for fluid...

Native Lazy Loading

9.4.2019
IntersectionObserver has made lazy loading a lot easier and more efficient than it used to be, but to do it really right you still gotta remove the src and such, which is cumbersome. It's definitely not as easy as: <img src="celebration.jpg" loading="lazy" alt="..." /> Addy Osmani says...

AI-Based Video Preview from Cloudinary (Sponsored)

8.4.2019
The early days of video on the web weren’t great. We started with custom browser plugins and codecs, then moved to Flash, and eventually we found our way HTML <video>. Once we solved the technology problem, we started using more video for content and advertising. The next problem...

Fixed Headers, On-Page Links, and Overlapping Content, Oh My!

3.4.2019
Let's take a basic on-page link: <a href="#section-two">Section Two</a> When clicked, the browser will scroll itself to the element with that ID: <section id="section-two"></section>. A browser feature as old as browsers themselves, just about. But as soon as...

Yet Another JavaScript Framework

1.4.2019
On March 6, 2018, a new bug was added to the official Mozilla Firefox browser bug tracker. A developer had noticed an issue with Mozilla's nightly build. The report noted that a 14-day weather forecast widget typically featured on a German website had all of a sudden broken and disappeared. Nothing...

A historical look at lowercase defaultstatus

1.4.2019
Browsers, thank heavens, take backward compatibility seriously. Ancient websites generally work just fine on modern browsers. There is a way higher chance that a website is broken because of problems with hosting, missing or altered assets, or server changes than there is with changes in...

Differential Serving

1.4.2019
There is "futuristic" JavaScript that we can write. "Stage 0" refers to ideas for the JavaScript language that are still proposals. Still, someone might turn that idea into a Babel plugin and it could compile into code that can ship to any browser. For some of these lucky proposals, Stage 0 becomes...

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...
