The masonry keyword allows you to create masonry grid layouts.

:defined represents any element that has been defined. This includes standard elements and custom elements that have been successfully defined.

In a media query, it’s obvious what width means. It always refers to the width of the viewport. With size container queries it’s not that obvious.

Cascade layers are one of the most interesting and useful additions to CSS recently. It will change the way we write CSS, how we use selectors, naming conventions, and probably also more things that I can’t think of right now.

There are a lot of interesting things you can do with the :has() pseudo-class. I’ve already covered some of them on day 26.

From now on you can transform elements with the translate, rotate, and scale properties.

Relative units used in container queries work differently than relative units in media queries.

With cascade layers comes a new CSS-wide property value, revert-layer.

There are several CSS-wide property values you can use to specify a particular defaulting behavior for a property explicitly.
