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.

When debugging, your attitude matters

12.4.2020
Julia Evans: I was debugging some CSS last week, and I think that post is missing something important: your attitude. Now – I’m not a very good CSS developer yet. I’ve never written CSS professionally and I don’t understand a lot of basic CSS concepts (I think I finally understood for the first...

Thinking in Behaviors, Not Screen Sizes

11.4.2020
Chase McCoy wrote a nifty post about the “gap problem” when making a grid of items. His argument might be summarized like this: how should we space elements with margins in CSS? He notes that the gap property isn’t quite ready for prime time when it comes to using it with flexbox, like this: .grid...

Tips for Writing Animation Code Efficiently

10.4.2020
I’ve been coding web animations and helping others do the same for years now. However, I have yet to see a concise list of tips focused on how to efficiently build animations, so here you go! I will be using the GreenSock Animation Platform (GSAP). It provides a simple, readable API and solves...

CSS Foldable Display Polyfill

9.4.2020
Foldable phones are starting to be a thing. Early days, for sure, but some are already shipping, and they definitely have web browsers on them. Stands to reason that, as web designers, we are going to want to know where that fold is so we can design screens that fit onto the top half and bottom...

Create Diagonal Layouts Like it’s 2020

9.4.2020
Nils Binder covers the ways: 1. Use an SVG in the form of a triangle. This technique is nicely described by Erik Kennedy on CSS-Tricks. 2. Hide part of your section using clip-path. Read Diagonal Containers in CSS by Sebastiano Guerriero or Sloped edges with consistent angle...

Creating Scheduled Push Notifications

8.4.2020
Scheduled is the key word there — that’s a fairly new thing! When a push notification is scheduled (i.e. “Take your pill” or “You’ve got a flight in 3 hours”) that means it can be shown to the user even if they’ve gone offline. That’s an improvement from the past where push notification...

The WebAIM Million—Updated

8.4.2020
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...

Learn Eleventy From Scratch

7.4.2020
The latest edition of Andy Bell’s Piccalilli landed in my inbox this morning with a sweet offer: preorder Andy’s course on learning Eleventy from scratch at a third of the price. Why the plug? No, not sponsorships or anything like that. I just happen to hear a heckuva lot about Eleventy...

How to Re-Create a Nifty Netflix Animation in CSS

7.4.2020
The design for Netflix’s browse page has remained pretty similar for a few years now. One mainstay component is the preview slider that allows users to scroll through content and hover on items to see a preview. One unique characteristic of the UI is its hover behavior. When a show preview...

CSS Findings From The New Facebook Design

7.4.2020
Ahmad Shadeed digs around the new Facebook’s front-end code. One that stood out to me: .element { inset: 4px 0; /* Which is equivalent to: top: 4px, bottom: 4px, left: 0, right: 0 */ } Whaaat? This is the first I’ve heard of the inset property. Ahmad said he saw it working...

A Grid of Logos in Squares

6.4.2020
Let’s build a literal grid of squares, and we’ll put the logos of some magazines centered inside each square. I imagine plenty of you have had to build a logo grid before. You can probably already picture it: an area of a site that lists the donors, sponsors, or that is showing off...

Continuous Deployments for WordPress Using GitHub Actions

6.4.2020
Continuous Integration (CI) workflows are considered a best practice these days. As in, you work with your version control system (Git), and as you do, CI is doing work for you like running tests, sending notifications, and deploying code. That last part is called Continuous Deployment (CD)....
