When I scroll down within the full page react's slides, though the page on the viewport of the screen the background color of the div does not change, I use react-on-screen npm package withing the full page react component but when I use the react-on-screen without full page react component it works great, I think when I scrolldown within the full-page-react slides the viewport don't think the new slides are new pages so the div background color doesn't change. Plus I tried to resize the window when the div in the last page is on the screen then the background is changed. Can you help me about this problem?

render() {

    const { height } = this.state;

    return (

      <Layout>

        <ReactFullpage

          refresh

          keyboardScrolling

          lazyLoading

          scrollOverflowReset={false}

          slidesNavigation={deger}

          onLeave={this.onLeave}

          render={({ state, fullpageApi }) => {

            return (

              <ReactFullpage.Wrapper>

                <React.Fragment>

                  <div className="section">

                    <p>Section 1</p>

                  </div>

                  <div className="section">

                    <div className="Index_LogoWrapper" style={{ height }}>

                      <LogoImage />

                      <div className="Index_ContactUsWrapper">

                        <div className="Index_ContactUs">

                      </div>

                    </div>

                  </div>

                  <div className="section">

                    <TrackVisibility>

                      <ComponentToTrack />

                    </TrackVisibility>

                  </div>

                </React.Fragment>

              </ReactFullpage.Wrapper>

            );

          }}

        />

      </Layout>

    );

  }

If the component you use to change the color relies on the scrolling position then you'll have to use the option scrollBar of fullPage.js in your react-fullpage component.

Otherwise I would encourage you to use the fullpage.js callbacks such as afterLoad or onLeave or even use the fullpage.js state classes that get added to the body element.

See one of my video tutorials about how to perform CSS 3 animations with fullpage.js state classes:
