The rule

After an introduction animation finishes, the introductory elements must be fully removed from the active layout.

Simply fading out the elements can cause unexpected user interface problems.

An introductory screen should be completely removed from the active layout. This means using a method like `display: none` in web development. Only changing the transparency of the intro screen is not enough. Fading only with opacity can leave parts of the intro screen still active. This can block user interaction or create visual issues.

A designer creates an app with a short intro animation. The developer makes the intro screen fade out using only opacity. After the intro, a button appears where the intro screen used to be. The user tries to tap the button, but it does not respond. The faded intro screen is still blocking the button, even though the user cannot see it.

How can a developer make sure a floating element, like a dropdown, appears above other page elements?

Floating elements need a special stacking order. This order is called a stacking context.

What common CSS mistakes cause display problems in web development?

Using an extra `div` with `overflow: hidden` can hide content. Absolutely positioned child elements can make the `:empty` selector unreliable.

How can a developer build a mobile view for a web application without breaking the desktop view?

A developer must treat mobile and desktop as two separate apps. They should use media queries to define distinct CSS layouts for each.

How can a developer ensure a user interface panel keeps a constant height and does not shift or 'dance'?

A developer must define a fixed total height for the main container. Every element inside this container needs a fixed slot.
