use crate::prelude::*;
/// # Align
/// Align content horizontally and vertically.
///
/// ## Example
/// ```
/// #set align(center)
///
/// Centered text, a sight to see \
/// In perfect balance, visually \
/// Not left nor right, it stands alone \
/// A work of art, a visual throne
/// ```
///
/// ## Parameters
/// - body: Content (positional, required)
/// The content to align.
///
/// - alignment: Axes<Option<GenAlign>> (positional, settable)
/// The alignment along both axes.
///
/// Possible values for horizontal alignments are:
/// - `start`
/// - `end`
/// - `left`
/// - `center`
/// - `right`
///
/// The `start` and `end` alignments are relative to the current [text
/// direction](@text/dir).
///
/// Possible values for vertical alignments are:
/// - `top`
/// - `horizon`
/// - `bottom`
///
/// To align along both axes at the same time, add the two alignments using
/// the `+` operator to get a `2d alignment`. For example, `top + right`
/// aligns the content to the top right corner.
///
/// ### Example
/// ```
/// #set page(height: 6cm)
/// #set text(lang: "ar")
///
/// مثال
/// #align(
/// end + horizon,
/// rect(inset: 12pt)[ركن]
/// )
/// ```
