Icons

Icons are loaded using @svgr/webpack. This is configured in element-web

Each .svg exports a ReactComponent at the named export Icon. Icons have role="presentation" and aria-hidden automatically applied. These can be overriden by passing props to the icon component.

eg

import { Icon as FavoriteIcon } from 'res/img/element-icons/favorite.svg';

const MyComponent = () => {
    return <>
        <FavoriteIcon>
        <FavoriteIcon className="mx_MyComponent-icon" role="img" aria-hidden="false">
    </>;
}

Styling

Icon components are svg elements and can be styled as usual.

// _MyComponents.scss
.mx_MyComponent-icon {
    height: 20px;
    width: 20px;

    * {
        fill: $accent;
    }
}

// MyComponent.tsx
import { Icon as FavoriteIcon } from 'res/img/element-icons/favorite.svg';

const MyComponent = () => {
    return <>
        <FavoriteIcon>
        <FavoriteIcon className="mx_MyComponent-icon" role="img" aria-hidden="false">
    </>;
}
