WTF is a Static API


Just like there is a movement to make more websites (and more of websites) from pre-rendered static files (Jamstack), so to might we consider moving content-based APIs to be static. Sean C Davis: A static API is simply a collection of flat JSON files that live on a content delivery...

`lh` and `rlh` units


There’s some new units I was totally unaware of from the Level 4 spec for CSS values! The lh unit is “equal to the computed value of line-height” and rlh is the same only of the root element (probably the <html> element) rather than the current element. Why would that...

The Anatomy of a Tablist Component in Vanilla JavaScript Versus React


If you follow the undercurrent of the JavaScript community, there seems to be a divide as of late. It goes back over a decade. Really, this sort of strife has always been. Perhaps it is human nature. Whenever a popular framework gains traction, you inevitably see people comparing it to rivals....

@property


The @property is totally new to me, but I see it’s headed to Chrome, so I suppose it’s good to know about! There is a draft spec and an “intent to ship” document. The code from that document shows: @property --my-property { syntax: "<color"; initial-value: green; ...

Chrome + System Fonts Snafu


There was just a bug late last year where system fonts (at least on Mac, I don’t know what the story was on other platforms) in Chrome appeared too thin and tracked-in at small sizes and too thick and tracked-out at larger sizes. That one was fixed, thankfully. But while it was a problem,...

Accessible Font Sizing, Explained


The Web Content Accessibility Guidelines (WCAG), an organization that defines standards for web content accessibility, does not specify a minimum font size for the web. But we know there’s such a thing as text that is too small to be legible, just as text that can be too large to consume. So,...

Innovating on Web Monetization: Coil and Firefox Reality


I still think Coil is cool. I have it installed on CSS-Tricks as a publisher and money trickles in. I have a paid account and I trickle out money to other sites that use it. I wrote about all that last year. This’ll explode to something huge if we actually get the Web Monetization API stuff....

How to Add Lunr Search to your Gatsby Website


The Jamstack way of thinking and building websites is becoming more and more popular. Have you already tried Gatsby, Nuxt, or Gridsome (to cite only a few)? Chances are that your first contact was a “Wow!” moment — so many things are automatically set up and ready to use.  There are some...

Styling in the Shadow DOM With CSS Shadow Parts 


Safari 13.1 just shipped support for CSS Shadow Parts. That means the ::part() selector is now supported in Chrome, Edge, Opera, Safari, and Firefox. We’ll see why it’s useful, but first a recap on shadow DOM encapsulation… The benefits of shadow DOM encapsulation I work at giffgaff where we have...

The WebAIM Million—Updated


This report made a big splash last year. It’s a large chunk of research that shows just how terribly the web does with accessibility. It’s been updated this year and (drumroll…) we got a little worse. I’ll use their blockquote: The number of errors increased 2.1% between...

Let a website be a worry stone


Ethan Marcotte just redesigned his website and wrote about how the process was a distraction from the difficult things that are going on right now. Adding new features to your blog or your portfolio, tidying up performance issues, and improving things bit by bit can certainly relieve a lot...

Wide Gamut Color in CSS with Display-P3


Here’s something I’d never heard of before: Display-P3 support in CSS Color Module Level 4 spec. This is a new color profile supported by certain displays and it introduces a much wider range of colors that we can choose from. Right now the syntax looks something like this in CSS: header...

CSS :nth-of-class selector


That's not a thing. But it kinda is! Bram covers how frustrating .bar:nth-child(2) is. It's not "select the second element of class .bar." It's "select the second element if it also has the class .bar." The good news? There is a real selector that does the former: :nth-child(2 of .bar) { } Safari...

Building a Real-Time Chat App with React and Firebase


In this article, we’ll cover key concepts for authenticating a user with Firebase in a real-time chat application. We’ll integrate third-party auth providers (e.g. Google, Twitter and GitHub) and, once users are signed in, we’ll learn how to store user chat data in the Firebase Realtime Database...
