A quick look behind the scenes The way you write CSS selectors does play a role i
For me, 2022 is the best year ever for CSS. We got a lot of new stuff supported in stable browsers and it’s just like living a dream. From CSS subgrid, :has selector, container queries, and the new viewport units. So many things to grasp, I understand - but I’m sure we agree that this is exciting, isn’t it? Recently, the Chrome team released experimental support for a new proposed CSS spec, style
There is no universal solution for making every kind of table responsive and usable on smaller screens, so we have to rely on various patterns, which Adrian explains in this two-part series. Tables allow us to organize data into grid-like format of rows and columns. Scanning the table in one direction allows users to search and compare the data while scanning in the other direction lets users get
A tree view (collapsible list) can be created using only HTML and CSS, without the need for JavaScript. Accessibility software will see the tree view as lists nested inside disclosure widgets, and the standard keyboard interaction is supported automatically. Giant planets Gas giants Jupiter Saturn Ice giants Uranus Neptune The HTML We begin with the HTML for simple nested lists: <ul> <li> Giant pl
One of the advantages of doing so is that the crop value will be automatically updated if you decide to change the value of your CSS variables (with no need to modify the mixin call) or if the line-height variable is modified at different media queries (with no need to re-use the mixin). The mixin explainedWhen using the lhCrop mixin, a ::before pseudo-element is created with a negative margin whi
UGURUS offers elite coaching and mentorship for agency owners looking to grow. Start with the free Agency Accelerator today. I bookmarked a tweet a few months ago, as it was a bonafide CSS trick and that’s what we love around here. The issue is: how do we make a full-browser-width container when we’re inside a limited-width parent? Starting Point This image is 100% wide as it’s limited-width paren
Browser compatibility A primary reason so many CSS features are set to cooperatively release is due to the efforts of Interop 2022. Before studying the Interop efforts, it's important to look at Compat 2021’s efforts. Compat 2021 The goals for 2021, driven by developer feedback via surveys, were to stabilize current features, improve the test suite and increase passing scores of browsers for five
In this article, we’ll be taking a closer look at two gradients: conic-gradient and radial-gradient. You’ll see how each one of them works in detail, what the differences and similarities are between them, how and where to use them, and some use cases for each. CSS gradients are a useful CSS feature that can be used to create interesting UI effects or even help us in drawing something without the
A while ago, I was inspecting facebook.com home page feed to learn and see how they build things out. I’m always curious to see how people write CSS. I noticed a very, very interesting border-radius value for the card component in the main feed. I shared the following tweet about this little discovery. Then, I received this reply from Miriam Suzanne: is it always 8px? That math looks like a toggle
IntroductionIn my humble opinion, the best websites and web applications have a tangible “real” quality to them. There are lots of factors involved to achieve this quality, but shadows are a critical ingredient. When I look around the web, though, it's clear that most shadows aren't as rich as they could be. The web is covered in fuzzy grey boxes that don't really look much like shadows. In this t
Working on a web design involves handling the design for different screen sizes. Based on those designs, the developer will use CSS media queries to detect the viewport width or height, and then alter the design based on that. This is how we used to design web layouts for the past 10 years, and it’s about to get even better. I have some good news for you. CSS Container queries, a long-requested fe
A collection of separator styles for horizontally dividing sections on a website. The dividers are created using several techniques, including styling pseudo-elements, using gradients and inserting SVG graphics with responsiveness in mind. Today we’d like to share some separator styles with you. When you have several sections in one page, it’s nice to separate them with some kind of line or backgr

Aspect ratio Aspect ratio is most commonly expressed as two integers and a colon in the dimensions of: width:height, or x:y. The most common aspect ratios for photography are 4:3 and 3:2, while video, and more recent consumer cameras, tend to have a 16:9 aspect ratio. Two images with the same aspect ratio.
