I'm curious as to why styled components weren't working before

I'm attempting to utilize the before on styled components in React, but it doesn't seem to be functioning correctly. Prior to adding before, the background image was displayed, but after its inclusion, the image is no longer showing up;

import styled from  'styled-components'
export const Container=styled.div `
&:before {
content:'';
top:0px;
left:0px;
right:0px;
position:absolute;
background-image:url(${({bg})=>bg});
background-size:cover;
}
`;

Answer №1

Experiment using ::before with double colons, and don't forget to specify height and width.
