Bevy ECSS

What is Bevy ECSS?

Bevy ECSS is a crate which allows the usage of a subset of CSS to interact with bevy_ecs. It's mainly aimed to apply styling on bevy_ui but it can be used by any component by implementing custom properties.

Why the name?

Just because Bevy ECS + CSS is a perfect fit!

Usage

To use Bevy ECSS just add a StyleSheet with a loaded css file to any entity and all style sheet rules will be applied to the entity and all its descendants (children of children of children and so on).

use bevy::prelude::*;
use bevy_ecss::prelude::*;

fn setup_awesome_ui(root: Entity, mut commands: Commands, asset_server: Res<AssetServer>) {
    commands
        .entity(root)
        .insert(StyleSheet::new(asset_server.load("sheets/awesome.css")));
}

That's it, now your UI will indeed look awesome!
