I started html when I was about 11 so I’m at 25 years.

I just discovered last night there’s an aspect ratio property…

https://caniuse.com/mdn-css_properties_aspect-ratio

It’s pretty new though. Less than 2 years I think.

I was just shocked. Last night I’m like “hmm need to maintain aspect ratio on this box. Maybe I can use calc and vh or something.

And this shocked up in Google. Rocked my world. I wanna go back across a bunch of products I’ve worked on over the years to fix stuff using this!

One of my favourite features now!

It is definitely magical! So many hours saved trying to find the right responsive break points for those particular card UIs.

aspect-ratio is a new standard, so don't feel too bad about that

Those are pretty new. text-underline-offset is another one that made my "fake" underlines obsolete

Also remember text-decoration-style, text-decoration-color and text-decoration-skip - setting this last one to 'ink' will make the underline, ahem, skip over the glyphs with descenders, adding to legibility

no problem. I work every day with CSS ... you can't know every new feature unless you have at least one use case to get know the new feature. The "old" technics are still working but if you want the benefits of new technics like text-decoration-skip-ink you have to use the new ones. So as long as you do not run into such problems like "skip-ink" you do not have to learn ne new ones.

That's a good side effect from using Tailwind CSS docs. They curate new CSS properties and add the most important (in their opinion) once they're supported by all modern browsers.
