Center

Center is a thin convenience wrapper around Align.

It exists for readability. When you want to center one child and nothing more, Center makes that intent obvious without exposing the lower-level struct directly.

Use it for empty states, spinners, single cards, or onboarding messages. Do not use it when you need multiple children or when you need more explicit positioning behavior.

Example

use fission::core::ui::Text;
use fission::prelude::*;

let node = Center {
    child: Box::new(Text::new("Loading...").into_node()),
}
.build(ctx, view);

Field table

Field	Type	Meaning	Notes / default behavior
child	Box<Node>	The node to center in the available space.	Required. Center has no extra alignment fields of its own.

Behavior and advice

Because Center simply builds an Align, it shares the same layout behavior: it fills bounded parent space and centers the child inside that space, while falling back to the child's size on unbounded axes.

Choose Center when you want the most direct way to say "put this in the middle." Choose Container when styling is also part of the job, and choose Row or Column when sibling layout matters.
