           <Route exact path="/" component={HomePage} />
           <Route path="/contentwrapper" component={Contentwrapper} />
         </Switch>
       </Router>
     </span>
     <Footer />

    this.handlePageChange = this.handlePageChange.bind(this);
    this.state = {};
  }   

  handlePageChange() {
    this.props.history.push("./contentwrapper");
    console.log("yes");
  }
