Using CSS Custom Properties to Adjust Variable Font Weights in Dark Mode

10.12.2020
Black isn’t always slimming. When recently testing a dark mode option for one of my sites, I experienced first-hand the issue that Robin Rendle addresses in this article. All of my page text — headings and body copy — appeared to bulk up when I switched to dark mode. And it didn’t matter what fonts...

Web Performance Calendar

7.12.2020
The Web Performance Calendar just started up again this year. The first two posts so far are about, well, performance! First up, Rick Viscomi writes about the mythical “fast” web page: How you approach measuring a web page’s performance can tell you whether it’s built for speed or whether it feels...

DRY-ing up styled-components

23.11.2020
I like working with styled-components. They allow you write CSS in your JavaScript, keeping your CSS in very close proximity to your JavaScript for a single component. As a front-end developer who loves to dissect a web page and break it down into reusable components, the idea of styled-components...

What’s Missing from CSS?

21.11.2020
The survey results from the State of CSS aren’t out yet, but they made this landing page that randomly shows you what one person wrote to answer that question. Just clicking the reload button a bunch, I get the sense that the top answers are: Container Queries Parent...

A Dynamically-Sized Sticky Sidebar with HTML and CSS

20.11.2020
Creating page content that sticks to the viewport as you scroll, something like a jump-to-anchor menu or section headings, has never been easier. Throw a position: sticky into your CSS ruleset, set the directional offset (e.g. top: 0) and you’re ready to impress your teammates with minimal effort....

Creating WebGL Effects with CurtainsJS

18.11.2020
This article focuses adding WebGL effects to <image> and <video> elements of an already “completed” web page. While there are a few helpful resources out there on this subject (like these two), I hope to help simplify this subject by distilling the process into a...

Parsing Markdown into an Automated Table of Contents

13.11.2020
A table of contents is a list of links that allows you to quickly jump to specific sections of content on the same page. It benefits long-form content because it shows the user a handy overview of what content there is with a convenient way to get there. This tutorial will show you how to parse...

How to Work With WordPress Block Patterns

12.11.2020
Just a little post I wrote up over at The Events Calendar blog. The idea is that a set of blocks can be grouped together in WordPress, then registered in a register_block_pattern() function that makes the group available to use as a “block pattern” in any page or post. Block patterns...

This page is a truly naked, brutalist html quine.

4.11.2020
Here’s a fun page coming from secretGeek.net. You don’t normally think “fun” with brutalist minimalism but the CSS trickery that makes it work on this page is certainly that. The HTML is literally displayed on the page as tags. So, in a sense, the HTML is both the page...

Websites We Like: Whimsical

3.11.2020
Whimsical is an app that lets you create flowcharts, wireframes, and mind maps but it was only earlier today that I spotted just how great the website is — especially the product pages. Check out this page where they describe how to use the Mind Maps feature where you can use the product right...

More on content-visibility

28.10.2020
Back in August 2020, when the content-visiblity property in CSS trickled its way into Chrome browsers, Una Kravets and Vladimir Levin wrote about it and we covered it. The weirdest part is that to get the performance value out of it, you pair it with contain-intrinsic-size on these big chunks...

How Hacker News Crushed David Walsh Blog

28.10.2020
Earlier this month, David’s heartfelt posting about leaving Mozilla made the front page of Hacker News. Traffic increased by 800% to his already-busy website, which slowed and eventually failed under the pressure. Request Metrics monitors performance and uptime for David’s blog, and our metrics...

Comparing Various Ways to Hide Things in CSS

27.10.2020
You would think that hiding content with CSS is a straightforward and solved problem, but there are multiple solutions, each one being unique. Developers most commonly use display: none to hide the content on the page. Unfortunately, this way of hiding content isn’t bulletproof because now that...

Core Web Vital Tooling

26.10.2020
I still think the Google-devised Core Web Vitals are smart. When I first got into caring about performance, it was all: reduce requests! cache things! Make stuff smaller! And while those are all very related to web performance, they are abstractly related. Actual web performance to users are things...

How to Make an Unobtrusive Scroll-to-Top Button

5.10.2020
A button to return to the top of the page allows the user to quickly return to the top of the page without making too much effort. This can be very useful when the page has a lot of content or which happens, for example, on one page websites, when infinite scrolling is used, or on mobile devices...

Achieving Vertical Alignment (Thanks, Subgrid!)

30.9.2020
Our tools for vertical alignment have gotten a lot better as of late. My early days as a website designer involved laying out 960px wide homepage designs and aligning things horizontally across a page using a 12-column grid. Media queries came along which required a serious mental shift. It solved...
