Percentage of respondents who have used `:has()`.

Of all the features included in the survey, :has() is both the most-used and the most-loved one. Also worth pointing out: Subgrid gets second place in the most-loved rankings, while aspect-ratio is #2 in usage and #3 in sentiment.

After Subgrid, line-clamp got the most comments, many of them from respondents with a negative opinion of the feature.

The least-used features were sibling-count and sibling-index, which makes sense since their browser support is still very new and limited. And the least-loved feature overall was Trigonometric Functions… no doubt due to the “trigonometry” part!

Finally, be sure to filter by “Widely Available” Baseline Status to see what features are available to use right now!

Year-over-year percentage increase in respondents who had heard about `light-dark()`.

Features Over Time

Looking at trends over time and in context paints quite an interesting picture. The feature with the single largest year-over-year usage increase is text-wrap: pretty, while the one with the largest awareness increase is light-dark().

Color functions also stand out for placing towards the bottom of the chart in terms of usage, which might mean they haven't yet found their audience.

Finally, the Appreciation tab lets us look at the difference in positivity between respondents interested in a feature and those who have actually used it. Anchor positioning shows a -12% drop-off, which could mean that the API isn't as user-friendly as people expect.

Layout Pain Points

While Grid is undeniably powerful, that power also comes with a steep learning curve that can turn using this fairly complex feature into a real pain point.

Further down the rankings, dealing with height, overflow, positioning, and alignment still all prove to be common issues for CSS developers.

Shapes & Graphics Pain Points

Now that we're fairly comfortable with rectangles, we've started looking towards the wider world of triangles, circles, and polygons. Sadly drawing these complex shapes remains tough with CSS only.

Which is why many of us resort to SVG–which is not without its own issues.

Colors Pain Points

Many respondents would like CSS to go beyond the light/dark dichotomy, and actually provide more tools for managing full-fledged theming, as well as do a better job ensuring proper contrast when picking colors.

And while new color spaces such as oklch() are certainly powerful, they also come with their own range of issues.

Interactions Pain Points

While many of us are waiting for better browser support for scroll-driven animations, others are pointing out potential accessibility issues with new interaction patterns such as carousels.

Another common pain point was the difficulty of “animating to auto”, something that is thankfully now possible!

We asked members of the CSS community to share their “pick of the year”

My 2025 Pick: text-wrap: balance;

I can’t remember the last time a new CSS property was introduced that I could just add to any stylesheet new and old. It’s a little magic one liner that makes your titles much nicer with zero downsides. Add it to your css resets!

Typography Pain Points

Controlling vertical text alignment (a.k.a. leading) in the browser has been an issue for as long as I can remember. Thankfully text-box-edge and text-box-trim promise to give us more granular tools to properly set type online.

My 2025 Pick: Font Clamp Generators

My pick of the year is all the font clamp generators that people have been creating and sharing. What’s great about them is that they are all so different so it accommodates different learning styles. Especially, if reading documentation alone doesn’t help understanding how something works.
