[psyopus69]

Dear Rafael, thanks a lot for your work!
Can you help me with next problem:
when i change slide, i don't see any color effects on buttons (with links on slides)
my code:

import AwesomeSlider from 'react-awesome-slider';
import AwsSliderStyles from 'react-awesome-slider/src/styles';
import AwesomeSliderStyles from 'react-awesome-slider/src/styled/fold-out-animation/index';
import React from "react";

const Test = (props) => {
return <AwesomeSlider animation="foldOutAnimation" cssModule={[AwsSliderStyles, AwesomeSliderStyles]}>

;
};

export {
Test,
};
