use crate::def_attribute;
def_attribute!(
/// Specify a color as the background of an element.
///
/// You can learn about the syntax of this attribute in [`Color Syntax`](crate::_docs::color_syntax).
///
/// ### Example
///
/// ```rust, no_run
/// # use freya::prelude::*;
/// fn app() -> Element {
/// rsx!(
/// rect {
/// background: "red"
/// }
/// )
/// }
/// ```
background,
/// Specify the opacity of an element's background color.
///
/// ### Example
///
/// ```rust, no_run
/// # use freya::prelude::*;
/// fn app() -> Element {
/// rsx!(
/// rect {
/// background: "red",
/// background_opacity: "0.5"
/// }
/// )
/// }
/// ```
background_opacity,
/// Specify borders for an element.
///
/// The `border` attribute follows this syntax:
/// border: `<width(s)> <alignment> <fill>`
///
/// Width specification follows CSS-like patterns:
/// - Single value: Applied to all sides
/// - Two values: First for top/bottom, second for left/right
/// - Three values: First for top, second for left/right, third for bottom
/// - Four values: Top, right, bottom, left (clockwise from top)
///
/// Alignment must be one of:
/// - `inner`: Border drawn inside the element bounds
/// - `outer`: Border drawn outside the element bounds
/// - `center` (default): Border centered on the element bounds
///
/// *Border alignment* determines how the border is positioned relative to the element's edge. Alignment can be `inner`, `outer`, or `center`.
///
/// Note: Borders exist outside the layout system, which means they will be drawn underneath child elements and may overlap with adjacent elements.
/// Add appropriate padding or margin to prevent border overlap with other content.
///
/// ### Examples
///
/// A solid, black border with a width of 2 pixels on every side. Border is aligned to the inside of the rect's edge.
///
/// ```rust, no_run
/// # use freya::prelude::*;
/// fn app() -> Element {
/// rsx!(
/// rect {
/// border: "2 inner black",
/// }
/// )
/// }
/// ```
///
/// A solid, red border with different widths on each side. Border is aligned to the center of the rect's edge.
///
/// ```rust, no_run
/// # use freya::prelude::*;
/// fn app() -> Element {
/// rsx!(
/// rect {
/// border: "1 2 3 4 center red",
/// }
/// )
/// }
/// ```
///
/// Borders can take any valid fill type, including gradients.
///
/// ```rust, no_run
/// # use freya::prelude::*;
/// fn app() -> Element {
/// rsx!(
/// rect {
/// border: "1 inner linear-gradient(red, green, yellow 40%, blue)",
/// }
/// )
/// }
/// ```
///
/// Similarly to the `shadow` attribute, multiple borders can be drawn on a single element when separated by a comma. Borders specified later in the list are drawn on top of previous ones.
///
/// ```rust, no_run
/// # use freya::prelude::*;
/// fn app() -> Element {
/// rsx!(
/// rect {
/// border: "6 outer red, 5 outer orange, 4 outer yellow, 3 outer green, 2 outer blue, 1 outer purple",
/// }
/// )
/// }
/// ```
border,
/// Draw a shadow of the element.
///
/// The `shadow` attribute follows this syntax:
/// shadow: `<x> <y> <intensity> <size> <color>`
///
/// - `x` and `y`: Define the offset position of the shadow
/// - `intensity`: Controls the shadow's blur amount
/// - `size`: Specifies the shadow's size/spread
/// - `color`: Any valid color value for the shadow
///
/// ### Example
///
/// ```rust, no_run
/// # use freya::prelude::*;
/// fn app() -> Element {
/// rsx!(
/// rect {
/// shadow: "0 0 25 2 rgb(0, 0, 0, 120)"
/// }
/// )
/// }
/// ```
shadow,
/// Round the corners of an element by a specified radius.
///
/// The `corner_radius` attribute follows this syntax:
/// corner_radius: `<all> | <tl-tr> <bl-br> | <tl> <tr> <br> <bl>`
///
/// - Single value: Applied to all corners
/// - Two values: First for top-left & top-right, second for bottom-left & bottom-right
/// - Four values: Top-left, top-right, bottom-right, bottom-left (clockwise from top-left)
///
/// This creates rounded corners on rectangular elements like rects or buttons.
///
/// ### Example
///
/// ```rust, no_run
/// # use freya::prelude::*;
/// fn app() -> Element {
/// rsx!(
/// rect {
/// corner_radius: "10" // All corners
/// }
/// )
/// }
/// ```
///
/// ```rust, no_run
/// # use freya::prelude::*;
/// fn app() -> Element {
/// rsx!(
/// rect {
/// corner_radius: "10 5" // 10 for top corners, 5 for bottom corners
/// }
/// )
/// }
/// ```
///
/// ```rust, no_run
/// # use freya::prelude::*;
/// fn app() -> Element {
/// rsx!(
/// rect {
/// corner_radius: "10 20 30 40" // Different radius for each corner
/// }
/// )
/// }
/// ```
corner_radius,
/// Control the smoothing effect for rounded corners to create a "squircle" effect.
///
/// Higher values create more of a squircle shape (rounded square), while lower values
/// result in a more traditionally rounded corner.
///
/// ### Example
///
/// ```rust, no_run
/// # use freya::prelude::*;
/// fn app() -> Element {
/// rsx!(
/// rect {
/// corner_radius: "10",
/// corner_smoothing: "75%"
/// }
/// )
/// }
/// ```
corner_smoothing,
