스크롤하여 꼬리말을 표시

Question

나는 시차를 사용하여 스크롤에 꼬리말을 숨기려고했지만 실제로는 이것이 작동하지 않는 img를 대상으로합니다.

나는 이것을 썼다.하지만 주 내용 페이지가 튀어 나와서 꼬리말을 천천히 드러내 기 시작했다. 풋터 슬라이드를 보는 바닥 http://red-team-design.com/simple-and-effective-dropdown-login-box/

스크롤 여기

$(window).on('scroll', function() { 
     if ($(window).scrollTop() > 85) { 
      $('.footer').show(); 
     } else { 
      $('.footer').hide(); 
     } 
    }); 

스크립트는 예이다.

순수한 CSS 방법이 있습니까? 여기에 트릭을 놓치지 마세요. 당신의 도움이

Answer 2

네, 순수 CSS의에 대한 감사합니다. 그냥 position: fixed 및 z-index: 0 것을 넣을 필요가 있기 (위해) 때문에, 같은 :

.footer {  
    position: fixed; 
    bottom: 0; 
    left: 0; 
    right: 0; 
    z-index: 0; 
} 

및 주요 내용 position: relative 및 z-index: 1 여기

.main-content {  
    position: relative; 
    z-index: 1; 
}
