I used classnames package as a tutorial but it doesn’t work.
Here is an error
Uncaught DOMException: Failed to execute ‘add’ on ‘DOMTokenList’: The token provided (‘skin-blue hold-transition sidebar-mini’) contains HTML space characters, which are not valid in tokens.
Here is a code
render() {
const bodyClassName = classnames(
{
'skin-blue': true,
'hold-transition': true,
'sidebar-mini': true,
});
return <div style={styles.root}>
<ReactBody className={bodyClassName}/>
<NavigationMenu/>
</div>
}
}
How to solve this problem?
