CSS content-visibility

The CSS language is full of small gaps which are frustrating to navigate. Between CSS properties to hide a container and its contents, there is still room for improvement. visibility: hidden keeps height and width integrity while display: none on a container hides everything. You can use .container > * to hide all contents of a container, but what if there was a better way?

There is a better way to hide the contents of an element while respecting the container's border and dimensions. That better way is using the content-visibility property:

.my-container.contents-loading {
  content-visibility: hidden;
}

A demo of such functionality:

Avoiding a .container > * selector by using content-visibility: hidden is so much nicer from a maintenance perspective!
