CSS or BS?

We show you a CSS property name. You tell us if it’s real or if we made it up. That’s it. It starts easy. It does not stay easy.

Don’t judge a book by its cover

Some neat CSS from Tess that’s a great example of progressive enhancement; these book covers look good in all browsers, but they look even better in some.

Responsive Letter Spacing – Cloud Four

Another clever use of clamp() and calc() for web typography, but this time it’s adjusting letter-spacing.

I’m more proud of these 128 kilobytes than anything I’ve built since | by Mike Hall | Jul, 2025 | Medium

I don’t normally link to articles on Medium—I respect you too much—and I do wish this were written on Mike Hall’s own site, but this is just too good not to share.

And don’t dismiss this as a nostalgiac case study from the past:

At no point did the constraints make the product feel compromised. Users on modern devices got a smooth experience and instant feedback, while those on older devices got fast, reliable functionality. Users on feature phones got the same core experience without the bells and whistles.

The constraints forced us to solve problems in ways we wouldn’t have considered otherwise. Without those constraints, we could have just thrown bytes at the problem, but with them every feature had to justify itself. Core functionality had to work everywhere, and without JavaScript crutches proper markup became essential.

This experience changed how I approach design problems. Constraints aren’t a straitjacket, keeping us from doing our best work; they are the foundation that makes innovation possible. When you have to work within severe limitations, you find elegant solutions that scale beyond those limitations.
