title: (React) CSSTransition with css modules
body: <p>I'm trying to implement a CSSTransition to a modal in my project. The problem is that I am using css modules.</p>
  
  <p><strong>My modal's render method</strong></p>
  
  <pre><code>render() {
          return (
              &lt;Aux&gt;
                  &lt;Backdrop
                      show={this.props.show}
                      clicked={this.props.modalClosed}/&gt;
                  &lt;CSSTransition
                      in={this.props.show}
                      timeout={1000}
                      mountOnEnter
                      unmountOnExit
                      classNames={?}
                  &gt;
                      &lt;div
                          className={classes.Modal}
                      &gt;
                          {this.props.children}
                      &lt;/div&gt;
                  &lt;/CSSTransition&gt;
              &lt;/Aux&gt;
          )
      }
  </code></pre>
  
  <p><strong>My Modal.css</strong></p>
  
  <pre><code>    .fade-enter {
  
      }
  
      .fade-enter-active {
          animation:openModal 0.4s ease-out forwards;
      }
  
      .fade-exit{
  
      }
  
      .fade-exit-active{
          animation: closeModal 0.4s ease-out forwards;
      }
  </code></pre>
  
  <p>What do i pass to the classNames attribute in the CSSTransition component in order to make it work?</p>
