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.

SVG file recommendations:

• Colours should not be defined absolutely. Use currentColor instead.
• There should not be a padding in SVG files. It should be added by CSS.

Example usage:

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

const MyComponent = () => {
    return <>
        <FavoriteIcon className="mx_Icon mx_Icon_16">
    </>;
}

If possible, use the icon classes from here.

Custom styling

Icon components are svg elements and may be custom styled as usual.

_MyComponents.pcss:

.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 className="mx_MyComponent-icon" role="img" aria-hidden="false">
    </>;
}
