If the value of totalNetworkScore is negative, I want to update the background color of a styled div to red.
If the value of totalNetworkScore is negative, I want to update the background color of a styled div to red.
If you're looking to assign conditional classes, consider using a ternary operator.
:class="{{totalNetworkScore ? 'green' : 'red'}}"
For styling in css:
.green {
background: green;
}
.red {
background: red;
}
To achieve this effect, consider utilizing the @emotion/core library with the following approach:
import { css } from "@emotion/core";
import React from "react";
checkNegative = counter => {
if (counter) {
return css`
background: green;
`;
}
};
class CustomComponent extends React.Component {
state = { counter: -1 };
render() {
return <div css={checkNegative(this.state.counter)}>some text</div>;
}
}
export default CustomComponent;
