(This is a sponsored post.) It’s probably no surprise to you that CSS-Tricks is (proudly) hosted on Cloudways, DigitalOcean’s managed hosting arm. Given both CSS-Tricks and Cloudways are part of DigitalOcean, it was just a matter of time before we’d come together this way. And here we are!…
CSS Tricks
Thank You (2024 Edition)
I’ ll be honest: writing this post feels like a chore some years. Rounding up and reflecting on what’ s happened throughout the year is somewhat obligatory for a site like this, especially when it’ s a tradition that goes back as far as 2007. “ Hey, look at all the cool…
A CSS Wishlist for 2025
2024 has been one of the greatest years for CSS: cross-document view transitions, scroll-driven animations, anchor positioning, animate to height: auto, and many others. It seems out of touch to ask, but what else do we want from CSS? Well, many things! We put our heads together and…
The Little Triangle in the Tooltip
Tooltips are like homemade food: everyone uses them and everyone has their own recipe to make them. If you don’ t remember a particular recipe, you will search for one, follow it, and go on with your day. This “ many ways to do the same thing” concept is general…
How to Create Multi-Step Forms With Vanilla JavaScript and CSS
Multi-step forms are a good choice when your form is large and has many controls. No one wants to scroll through a super-long form on a mobile device. By grouping controls on a screen-by-screen basis, we can improve the experience of filling out long, complex forms. But when…
Fluid Superscripts and Subscripts
Superscripts and subscripts are essential elements in academic and scientific content — from citation references to chemical formulas and mathematical expressions. Yet browsers handle these elements with a static approach that can create significant problems: elements become either too small on mobile devices or disproportionately large on desktop…
CSSWG Minutes Telecon (2024-12-04): Just Use Grid vs. Display: Masonry
The CSS Working Group (CSSWG) meets weekly (or close to it) to discuss and quickly resolve issues from their GitHub that would otherwise be lost in the back-and-forth of forum conversation. While each meeting brings interesting conversation, this past Wednesday (December 4th) was special. The CSSWG met to…
Yet Another Anchor Positioning Quirk
I strongly believe Anchor Positioning will go down as one of the greatest additions to CSS. It may not be as game-changing as Flexbox or Grid, but it does fill a positioning gap that has been missing for decades. As awesome as I think it is, CSS Anchor Positioning…
One of Those “Onboarding” UIs, With Anchor Positioning
Welcome to “ Anchor Positioning 101” where we will be exploring this interesting new CSS feature. Our textbook for this class will be the extensive “ Anchor Positioning Guide” that Juan Diego Rodriguez published here on CSS-Tricks. I’ m excited for this one. Some of you may remember when CSS-Tricks released…
WordPress Multi-Multisite: A Case Study
Follow Up: We Officially Have a CSS Logo!
As a follow up to the search for a new CSS logo, it looks like we have a winner! Since our last post, the color shifted away from a vibrant pink to a color with a remarkable history among the CSS community: rebeccapurple CodePen Embed Fallback With 400…
Alt Text: Not Always Needed
Alt text is one of those things in my muscle memory that pops up anytime I’ m working with an image element. The attribute almost writes itself. < img src=”image.jpg” alt=””> Or if you use Emmet, that’ s autocompleted for you. Don’ t forget the alt text! Use it even if there’ s…
Solved by CSS: Donuts Scopes
Imagine you have a web component that can show lots of different content. It will likely have a slot somewhere where other components can be injected. The parent component also has its own styles unrelated to the styles of the content components it may hold. This makes a…
Anchoreum: A New Game for Learning Anchor Positioning
You’ ve played Flexbox Froggy before, right? Or maybe Grid Garden? They’ re both absolute musts for learning the basics of modern CSS layout using Flexbox and CSS Grid. I use both games in all of the classes I teach and I never get anything but high-fives from my students…
Popping Comments With CSS Anchor Positioning and View-Driven Animations
The State of CSS 2024 survey wrapped up and the results are interesting, as always. Even though each section is worth analyzing, we are usually most hyped about the section on the most used CSS features. And if you are interested in writing about web development (maybe start…
Fluid Everything Else
We all know how to do responsive design, right? We use media queries. Well no, we use container queries now, don’t we? Sometimes we get inventive with flexbox or autoflowing grids. If we’re feeling really adventurous we can reach for fluid typography. I’m a bit uncomfortable that responsive…
State of CSS 2024 Results
They’ re out! Like many of you, I look forward to these coming out each year. I don’ t put much stock in surveys but they can be insightful and give a snapshot of the CSS zeitgeist. There are a few little nuggets in this year’ s results that I find…
Tooltip Best Practices
In this article, I try to summarize the best practices mentioned by various accessibility experts and their work (like this, this, and this) into a single article that’ s easy to read, understand, and apply. Let’ s begin. What are tooltips? Tooltips are used to provide simple text hints for…
Come to the light-dark() Side
You’ d be forgiven for thinking coding up both a dark and a light mode at once is a lot of work. You have to remember @media queries based on prefers-color-scheme as well as extra complications that arise when letting visitors choose whether they want light or dark mode…
Clarifying the Relationship Between Popovers and Dialogs
The difference between Popovers (i.e., the popover attribute) and Dialogs (i.e., both the < dialog> element and the dialog accessible role) is incredibly confusing — so much that many articles (like this, this, and this) have tried to shed some light on the issue. If you’ re still feeling confused, …
