Custom Properties
- https://adactio.com/journal/17106 A bridge between JavaScript and CSS, JK did some work where he updated a class name from JavaScript (el.classList.add). He automatically thought of updating a class name because, frankly, that’s how I’ve always done it. I’d say about 90% of the DOM scripting I’ve ever done involves toggling the presence of class values: accordions, fly-out menus, tool-tips, and other progressive disclosure patterns. But really, I should try to avoid touching the DOM at all. It can have performance implications, possibly triggering unnecessary repaints and reflows. Now with custom properties, there’s a direct line of communication between JavaScript and CSS. No need to use the HTML as a courier. A lot of CP’s potential comes from the fact that they’re not just confined to CSS.
A Utility Class for Covering Elements (on CSS { In Real Life })
Need to overlay one HTML element on top of and fully covering another, such as a heading with translucent background on top of an image? Michelle Barker has us covered with this blog post in which she creates an overlay utility to handle this. She firstly shows how it can be accomplished with positioning, then modernises her code using the inset CSS logical property, before finally demonstrating a neat CSS Grid based approach.
Newsletters, by Robin Rendle
A fantastic so-called “Scroll Story” from Robin Rendle. In his own words it’s “an elaborate blog post where I rant about a thing” however given the beautiful typography, layout and illustrations on show I think he’s selling it a little short!
Create an Automatically Responsive Flexbox Gallery (on egghead.io)
Here’s a lovely intrinsically responsive (no media queries) photo gallery solution from Stephanie Eckles. It can accommodate differently sized images and achieves its layout by a combination of flexbox features (flex-wrap, flex-basis) and by applying object-fit: cover to photos to make them fully cover their parent list items.
Browser Support Heuristics
In web development it’s useful when we can say “if the browser supports X, then we know it also supports Y”.
Creating websites with prefers-reduced-data (on polypane.app)
Even though more and more people get access to the internet every day, not all of them have fast gigabit connections or unlimited data. Using the media query prefers-reduced-data we can keep our sites accessible to everyone.
Minimalist Container Queries
Scott Jehl’s experimental take on a container/element query aimed at letting us set responsive styles for our elements based on their immediate context rather than that of the viewport.
I made a quick and minimal take on approximating Container/Element Queries using a web component and basic CSS selectors.
Cheating Entropy with Native Web Technologies (on Jim Nielsen’s Weblog)
This is why, over years of building for the web, I have learned that I can significantly cut down on the entropy my future self will have to face by authoring web projects in vanilla HTML, CSS, and JS. I like to ask myself questions like:
- Could this be done with native ES modules instead of using a bundler?
- Could I do this with DOM scripting instead of using a JS framework?
- Could I author this in CSS instead of choosing a preprocessor?

A Guide To The State Of Print Stylesheets In 2018 - Smashing Magazine
Rachel Andrew explains how to write CSS for a nicely optimised printed page that uses a minimum of ink and paper and ensures that content is easy to read.
Create a line break while maintaining inline status (on Piccalilli)
Sometimes you want to create a line break after an inline element, while retaining that inline element’s inline status.
Daniel Post shared a really cool performance-optimisation trick for Eleventy on Twitter the other day. When statically generating your site you can loop through your pages and, for each, use PurgeCSS to find the required CSS, then inline that into the <head>. This way, each page contains only the CSS it needs and no more!
I’ve just installed this on my personal site. I was already inlining my CSS into the <head> but the promise of only including the minimum CSS that each specific page needs was too good to resist.
Turned out it was a breeze to get working, a nice introduction to Eleventy transforms, and so far it’s working great!
Three CSS Alternatives to JavaScript Navigation (on CSS-Tricks)
In general this is a decent article on non-JavaScript-based mobile navigation options, but what I found most interesting is the idea of having a separate page for your navigation menu (at the URL /menu, for example).
Who said navigation has to be in the header of every page? If your front end is extremely lightweight or if you have a long list of menu items to display in your navigation, the most practical method might be to create a separate page to list them all.
The Simplest Way to Load CSS Asynchronously (Filament Group)
Scott Jehl of Filament Group demonstrates a one-liner technique for loading external CSS files without them delaying page rendering.
Color Theme Switcher (on mxb.dev)
Max shows us how to build a colour theme switcher to let users customise your website. He uses a combination of Eleventy, JSON, Nunjucks with macros, a data attribute on the html element, CSS custom properties and a JavaScript based switcher.
3 Popular Website Heroes Created With CSS Grid Layout (on Modern CSS Solutions)
Some serious CSS Grid positioning, image manipulation and alpha transparency ninjitsu on display here from Stephanie Eckles!
This episode explores creating website heroes - aka “headers” - with one of my favorite ways to use CSS grid layout: by turning it into a canvas.
Sass and clamp (on Adactio: Journal)
Given what we can now do with CSS, do we still need Sass?
Sass was the hare. CSS is the tortoise. Sass blazed the trail, but now native CSS can achieve much the same result.
Striking a Balance Between Native and Custom Select Elements (on CSS-Tricks)
We’re not going to try to replicate everything that the browser does by default with a native select element. We’re going to literally use a select element when any assistive tech is used. But when a mouse is being used, we’ll show the styled version and make it function as a select element.

How to create an accordion hover effect with box-shadows (Sarah L. Fossheim)
In this tutorial we'll use the box-shadow property to create a layered card component, and animate it on hover.
CSS Triggers
Check whether or not a CSS property is a good candidate for smooth animation based on whether updates to its value trigger expensive changes (to, for example, “element geometry”) causing layout updates and repaints.
4 Ways to Animate the Color of a Text Link on Hover | CSS-Tricks
Let’s create a pure CSS effect that changes the color of a text link on hover – but slide that new color in instead of simply swapping colors.
The Contrast Triangle
Removing underlines from links in HTML text presents an accessibility challenge. In order for a design to be considered accessible, there is now a three-sided design contraint - or what I call "The Contrast Triangle". Your text, links and background colors must now all have sufficient contrast from each other. Links must have a contrast ratio of 3:1 from their surrounding text. By not using underlines, a design has to rely on contrast alone to achieve this.

Using CSS Custom Properties to streamline animation
Thanks to a great tip from Lucas Hugdahl on Twitter, here’s how to use CSS custom properties (variables) in your transforms so you don't need to rewrite the whole transform rule in order to transition (animate) a single property.
You don’t need a media query for that: #1 Inline content separators
Create a more flexible component which allows the text to wrap based on the content rather than the viewport size.
Animating the underlining of multi-line text
Cassie Evans shows us how to combine background–size, a linear-gradient based background-image and a keyframe animation (all in HTML and CSS) for a lovely progressive underline effect on multi-line text.
Intrinsically Responsive CSS Grid with minmax and min
Evan Minto notes that flexible grids created with CSS Grid’s repeat, auto-fill, and minmax are only intrinsically responsive (responsive to their container rather than the viewport) up to a point, because when the container width is narrower than the minimum width specified in minmax the grid children overflow.
CSS pointer-events to the rescue
Sometimes, for reasons unknown, we find that clicking or tapping an element just isn’t working. Here’s a CSS-based approach that might help.

How to control SVG icon size and colour in context
A while back I read a great SVG icon tip from Andy Bell which I’d been meaning to try and finally did so today. Andy recommended that for icons with text labels we set the width and height of the icons to 1em since that will size them proportionately to the adjacent text and additionally lets us use font-size to make any further sizing tweaks.
Box Shadow around the full box
Sometimes when coding a UI element you want a shadow around the whole box. However, most CSS box-shadow examples/tutorials tend to show inset box-shadows or ones that otherwise sit off to the side.
Here’s how to apply box-shadow to the whole box for a simple but nice effect.
.box-with-shadow {
box-shadow: 0 0 4px #ccc;
}And here’s how it looks:
Styling a Select Like It’s 2019 (Filament Group, Inc.)
Recently, we’d seen some articles suggest that things haven’t changed a great deal with select's styling limitations, but I decided to return to the problem and tinker with it myself to be sure. As it turns out, a reasonable set of styles can create a consistent and attractive select across new browsers, while remaining just fine in older ones too.
