or, instead of writing valuable content, let me just release another shitty webpage with CSS tools

Project Wallace @projectwallace.com · 14/09/2026

🍾 NEW: Baseline overview Quickly scan the Baseline status of your website's CSS! 🩻 www.projectwallace.com/baseline-ove...

A portion of a page from project wallace. It shows three panels, two on the top, one at the bottom. The top left panel is titled "Baseline status summary" and shows a table and graph showing that 26 feaures are widely available, 2 newly available and 5 limited available. The top right panel is titled "Widely available features by year" and shows a table with all years since 2018 and each year has a bar graph of how many features of that year are used. The bottom panel shows a huge table with each used feature, the amount of usage, the dates fro when it became newly available, widely available, often a link to caniuse.com, and finally a column that indicates browser support for Edge, Chrome, Firefox and Safari.

Mixing web-features with wallace's CSS analysis and you get... a new tool for CSS archeologists! h/t @patrickbrosset.com for pointing me to github.com/web-platform...

A bar chart titles "Widely available, by year". There are 12 columns for the years 2018 through 2026 and "not yet widely", "not baseline" and "untracked". The bars for these last three are grayed out.

Values per item:

2018: 3560
2019: 1818
2020: 107
2021: 9
2022: 182
2023: 222
2024: 120
2025: 58
2026: 10
not yet widely: 8
not baseline: 49
untracked: 671

Project Wallace stylelint overview. There are three errors. 1 is for an `if()` that contains only an `else` branch. 2 is for an `if()` without an `else`. 3 is for an `else` that isn't the last condition in the `if()`.

npmx.dev's view of the `@projectwallace/css-design-tokens` package. It shows a bright green/positive banner saying "Package size decreased since v0.11.8!🎉 Install size reduced by 93% (15.8 MB smaller)"

Okay, so I learned a thing about Grids today. Many of my components have these declarations to make spacing nice: `display: grid; gap: 2rem`. Apparently, `grid-template-columns` is now implicitly set to `auto`. Yada yada, 2018 @chriscoyier.net has my back! css-tricks.com/preventing-a...

Dogfooding the Wallace stylelint plugin on an upcoming new page on the website. There's so much to improve: more granular error ranges, better error messaging, subtle bugs to fix. But it'll be good!

webpage with 3 columns. first column is really narrow and has radio buttons for presets: recommended, meintainability, performance and correctness. Second column shows a bunch of CSS with lots of red squiggly lines, indicating errors. Third column shows a table of all errors found and one row selected.

"Your CSS has dirty secrets and Wallace knows them." is just a title that hits. Immediate guilt and fear flow through your veins. "Does it know about... the floats?", you ask yourself. Ha, who are you kidding, of course it does. And that tiny 8px font-size. Thought you'd get away with that, did ya?

Tried some wildly different fonts but I think Teko is just the best reflection of my border-radius:0 design. Added 2 gradients to the header at a late stage, quite like them. Added a lot more spacing to the homepage, but made the forms to submit URL a bunch smaller.

Project Wallace homepage. A hero banner says "Your css has dirty secrets and Wallace knows them" against a mostly dark gray background.

Project Wallace analysis page. The page header shows the page's title inline with toggles for choosing whether to analyze a URL, file or pasted CSS. The same gradient dark background is used.

Partial screenshot of a blog post that announces The CSS Selection

Excerpt from The CSS Selection about @media:

"The max-width and min-width features are quite unexpectedly used on most websites (88% and 86%). I did not expect prefers-reduced-motion to have such a great adoption rate even though it’s almost half of that of the top two. There are some other surprises here, like forced-colors being used a bunch more than prefers-color-scheme."

Did you know @projectwallace.com has a CSS Complexity calculator? It's a fun complement to CSS Specificity. It doesn't measure the impact a selector has but the number of parts that it has. more parts: harder to understand for humans. www.projectwallace.com/selector-com...

We're progressing! Hoping to launch The CSS Selection later this week, maybe before the weekend if all goes well. Also hoping that the estimated reading time of 45-60 minutes won't scare people too much 😅

A social media preview image, or card. The title is "The CSS Selection". Subtitled: "The state of real-world CSS usage, 2026 edition". The bottom shows some stats: 100+ metrics, 100,000 websites, 41% use :has(), 9.61% use @container. The design shows a bright grean/teal outline and a dark background with a dark-green to dark-gray gradient from top to bottom. There are two seemingly random rectangular shapes in the top right, probably visual decoration.

If you really hate looking at unused custom properties, maybe clean them up? 😇 I know looking at unused custom properties not applied in devtools is not the same as potentially flawed static analysis on a large chunk of CSS, but hey...
