State of CSS 2024

CSS Usage

No matter how you use CSS, the data shows that making sure your code works across all browsers is still a concern, especially for newer features such as :has().

Testing Environments

An encouraging sign of accessibility's growing importance, screen reader testing has gone up from 16.6% to 19% year-over-year.

While this data is unsurprising, it's a nice reminder that CSS can do a lot more than format webpages.

In what context do you primarily use CSS?

Design Methodology

While a large majority of respondents use CSS to implement pre-existing designs, it'll be interesting to see if this changes as design apps evolve, and AI tools become capable of going straight from idea to code.

Which of these best describes how you primarily design with CSS?

CSS vs JavaScript Balance

Even in the context of a CSS survey, it turns out a majority of respondents still spend most of their time in the JavaScript ecosystem. Only time will tell if this too will shift now that CSS is becoming more capable.

How do you divide your time between writing CSS (including HTML markup) and JavaScript code?

Browser Incompatibilities

There are few worse feelings that knowing a new feature will solve your issue perfectly, yet not being able to use it because of poor browser support.

This is the case with Anchor Positioning, a promising new feature that is sadly not yet broadly supported.

Container Queries on the other hand are available at a baseline level and ready to be used, despite showing up in many respondent's answers!

Are there any existing CSS features that you have difficulties using (or avoid altogether) because of lack of support, or differences between browsers?

My 2024 Pick: Getting Stuck: All the Ways position:sticky Can Fail

In all my years in CSS, position: sticky has to be one of the most frustrating capabilities, but it’s also extremely useful. I always wanted to write a guide to help people with that but luckily I don’t need to because Kilian nailed this one.

Missing Features

In the absence of a magic wand that lets us conjure up any CSS feature we can dream of, the best we can hope for is that this data can help push browser vendors in the right direction!

The good news: conditional logic, mixins, and masonry layouts are all currently being worked on in some form or another!

My 2024 Pick: Scroll-driven Animations

This is a game changer that will soon be supported in all major browsers. It's incredible that what once required a lot of JavaScript is now achievable with just a few lines of CSS.
