PPK looks at aspect-ratio, a CSS property for layout that, for the most part, does exactly what you would think it does. It’s getting more interesting as it’s behind a flag in Firefox and Safari now, so we’ll have universal support pretty darn soon. I liked how he called it a “weak declaration” whic..

There are four keywords that are valid values for any CSS property (see the title). Of those, day to day, I’d say I see the inherit used the most.

It is often used for highlighting elements, for example, the :focus style. In this article, let’s put a point..
