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.
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!
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-basis) and by applying
object-fit: cover to photos to make them fully cover their parent list items.
In web development it’s useful when we can say “if the browser supports X, then we know it also supports Y”.
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.
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.
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?
How to break out to full-bleed, various ways.
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.
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!
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.
Scott Jehl of Filament Group demonstrates a one-liner technique for loading external CSS files without them delaying page rendering.
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.
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.
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.
Modern CSS Solutions for Old CSS Problems
A handy tool that generates the required HTML and CSS for various section separator effects (including diagonal lines, spikes, and waves) by cleverly manipulating backgrounds and generated content.
Here’s a handy resource providing BEM-based naming suggestions for some of the most common web components.
Here’s Chris Ferdinandi with a list of resources to help those who are new to web development get started. I’m keeping this one handy so I can share it with any friends who’re thinking of getting into this game.
In this tutorial we'll use the box-shadow property to create a layered card component, and animate it on hover.
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.
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.
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.
The BBC Global Experience Language (GEL) Technical Guides are a series of framework-agnostic, code-centric recommendations and examples for building GEL design patterns in websites. They illustrate how to create websites that comply with all BBC guidelines and industry best practice, giving special emphasis to accessibility.
I first got into web design/development in the late 90s, and only as I type this sentence do I realize how long ago that was. Here’s a history of CSS and web design, as I remember it.
I wanted to see if it was possible to create SVG charts that would work without JS. Well, it is. I've also created an experimental Svelte component library called Pancake to make these techniques easier to use.
Here’s Rob Weychert advocating a combination of CSS custom properties,
calc() and Sass to automate the construction of a flexible typographic scale in CSS.

Create a more flexible component which allows the text to wrap based on the content rather than the viewport size.
Cassie Evans shows us how to combine
background-image and a keyframe animation (all in HTML and CSS) for a lovely progressive underline effect on multi-line text.
Evan Minto notes that flexible grids created with CSS Grid’s
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.
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.
Automatically compiles SASS/SCSS files to .css and .min.css upon saving. You may also quickly compile all SCSS/SASS files in your project.
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
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.
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.
And here’s how it looks:
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.
A handy tool for identifying colours – provided in numerous different CSS-ready formats – and creating a complimentary colour palette from an image you upload or provide as a URL.
Great resource from CSS Grid expert Rachel Andrew, with the Patterns and Examples sections which provide quick-start grid layouts being particularly handy.
