GSAPを使用したスクロールアニメーションについて

Question

アニメーションにGSAPを使用しています。ユーザーがマウスホイールをスクロールするとスクロールアニメーションが必要です。アニメーションはページの読み込みに取り組んでいます。私はコンテンツがスクロールにアニメートする必要があります。最初の2つの記事は機能していますが、スクロールするときにはアニメーションが機能しません。

(function() { 
 
    var content = document.getElementById("content"); 
 
    var xScroll = 0; // initialize 
 
    function scrollHorizontally(e) { 
 
     xScroll = xScroll+e.deltaY*20; 
 
     // set limits to avoid overshooting and stucking at beginning or end 
 
     var max = document.getElementById("content").innerWidth; 
 
      if (xScroll <= 0) { 
 
       xScroll = 0; 
 
      } else if (xScroll >= max) { 
 
       xScroll = max; //replace with the width of the scrollable container 
 
      } 
 
     // scroll smooth to xScroll 
 
     TweenLite.to(content, 1, { ease: Power1.easeOut, scrollTo:{x:xScroll} }); 
 
     var rt = ($(window).width() - ($(".active_05").offset().left)); 
 
     if(rt>200) 
 
     { 
 
      $(".about_menu").addClass("active"); 
 
     } 
 
     else 
 
     { 
 
        
 
     $(".about_menu").removeClass("active"); 
 
     } 
 
     e.preventDefault(); 
 
    } 
 
    if (content.addEventListener) { 
 
     // Standard 
 
     content.addEventListener("wheel", scrollHorizontally, false); 
 
    } else { 
 
     // IE 6/7/8 
 
     content.attachEvent("onmousewheel", scrollHorizontally); 
 
    } 
 

 

 
     var article_1=document.getElementById("article_1"); 
 
    TweenLite.from(article_1, .5, { ease: Power0.easeOut, y: 10 }); 
 

 

 
    var article_2=document.getElementById("article_2"); 
 
    TweenLite.from(article_2, .5, { ease: Power0.easeOut, y: 10 }); 
 
    var article_3=document.getElementById("article_3"); 
 
    TweenLite.from(article_3, .5, { ease: Power0.easeOut, y: 15 }); 
 

 
     var article_3=document.getElementById("article_4"); 
 
    TweenLite.from(article_3, .5, { ease: Power0.easeOut, y: 15 }); 
 

 
     var article_3=document.getElementById("article_5"); 
 
    TweenLite.from(article_3, .5, { ease: Power0.easeOut, y: 15 }); 
 

 

 
})();
