Style

Learn how the style attributes work.

background

The background attribute will let you specify a color as the background of the element.

You can learn about the syntax of this attribute here.

Example:

#![allow(unused)]
fn main() {
fn app(cx: Scope) -> Element {
    render!(
        rect {
            background: "red"
        }
    )
}
}

Compatible elements: rect

shadow

The shadow attribute let's you draw a shadow outside of the element.

Syntax: <x> <y> <intensity> <size> <color>

Example:

#![allow(unused)]
fn main() {
fn app(cx: Scope) -> Element {
    render!(
        rect {
            shadow: "0 0 25 2 rgb(0, 0, 0, 120)"
        }
    )
}
}

corner_radius & corner_smoothing

The corner_radius attribute let's you smooth the corners of the element, with corner_smoothing you can archieve a "squircle" effect.

Example:

#![allow(unused)]
fn main() {
fn app(cx: Scope) -> Element {
    render!(
        rect {
            corner_radius: "10",
            corner_smoothing: "75%"
        }
    )
}
}

Compatible elements: rect

border

You can add a border to an element using the border and border_align attributes.

  • border syntax: [width] <solid | none> [color].
  • border_align syntax: <inner | outer | center>.

Example:

#![allow(unused)]
fn main() {
fn app(cx: Scope) -> Element {
    render!(
        rect {
            border: "2 solid black",
            border_align: "inner"
        }
    )
}
}

Compatible elements: rect

overflow

Specify how overflow should be handled.

Accepted values: clip | none.

Example:

#![allow(unused)]
fn main() {
fn app(cx: Scope) -> Element {
    render!(
        rect {
            overflow: "clip"
            width: "100",
            height: "100%",
            rect {
                width: "500",
                height: "100%",
                background: "red",
            }
        }
    )
}
}

  • With RGB: rgb(150, 60, 20)
  • With RGB and alpha: rgb(150, 60, 20, 70)
  • With HSL: hsl(28deg, 80%, 50%)
  • With HSL and alpha: hsl(28deg, 80%, 50%, 25%)
