我有一點困難讓覆蓋導航覆蓋頁面內的所有元素。當我爲頁面內的單個部分創建容器或行時,疊加層似乎不覆蓋。覆蓋導航不包括頁面上的所有元素

下面的代碼,並鏈接到codepen http://codepen.io/anon/pen/aOGYdy

      results = []; 
      while (i >= 0) { 

       if (sectionY - px < windowY && windowY < sectionY + px) { 
        time = Math.abs(windowY - sectionY)/speed; 
        $(document.body).animate({ scrollTop: sectionY }, time, 'swing'); 
       } 
       results.push(i--); 
      } 
     }, wait));

}.call(this)); 

//slide 
// Cache selectors 
var lastId,

只需添加一個Z-指數.overlay

http://codepen.io/anon/pen/oXdqYy

.overlay { 
    position: fixed !important; 
    background: #22a7f0; 
    top: 0; 
    left: 0; 
    width: 100%; 
    height: 0%; 
    opacity: 0; 
    visibility: hidden; 
    -webkit-transition: opacity .35s, visibility .35s, height .35s; 
      transition: opacity .35s, visibility .35s, height .35s; 
    overflow: hidden; 
    z-index: 99; 
}
