07:22 - Why?

Container queries are media queries for components (e.g. they are based on the element’s size, not the browser). This is in line with how we write components. It will change the way we write CSS.

08:49 - The Syntax

Containers need to be defined as containers via containment context .container { contain: size layout; }

New contain value:

.inline-container { contain: inline-size; }

This is the same as the logical properties. Assuming you read LTR, or RTL:

size - width and height inline-size = width block-size = height /* @container { } */ @container (inline-size > 45em) { .media-object { grid-template: "img content" auto / auto 1fr; } }
