Affix

페이지를 위아래로 스크롤 할 때 메뉴가 항상 표시되고 해당 위치에 고정

탐색메뉴 또는 소셜아이콘 버튼과 함께 사용되어 페이지를 위아래로 스크롤하는 동안 특정 영역에 고정 되도록 함

스크롤 위치에 따라 동작을 켜고 끌 수 있음 (CSS position이 static에서 fixed로 변함)

  1. 연결 플러그인은 .affix, .affix-top 및 .affix-bottom의 세 가지 클래스를 전환함. (각 클래스는 특정 상태를 나타냄) .affix 클래스에 fixed position을 제외하고 실제 위치를 처리하려면 CSS 속성을 추가해야 함

  2. 플러그인은 .affix-top 또는 .affix-bottom 클래스를 추가하여 요소가 맨 위 또는 맨 아래 위치에 있음을 나타냄 (이 시점에서는 CSS로 위치를 지정할 필요가 없음)

  3. 부착된 요소를 지나 스크롤하면 실제 부착이 트리거됨 여기서 플러그인은 .affix-top 또는 .affix-bottom 클래스를 .affix 클래스(설정 위치: fixed)로 바꿈. 이 때 CSS 상단 또는 하단 속성을 추가하여 부착된 요소를 페이지에 배치해야 함

  4. 하단 오프셋이 정의된 경우, 이 오프셋을 지나 스크롤하면 .affix 클래스가 .affix-bottom으로 바뀜, (오프셋은 선택적이므로 하나를 설정하면 적절한 CSS를 설정해야 함) 이 경우 필요할 때 절대 위치를 추가

How Affix works

<!--  --> 
<nav class="navbar navbar-inverse" data-spy="affix" data-offset-top="197">
  <ul class="nav navbar-nav">
    <li class="active"><a href="#">Basic Topnav</a></li>
    <li><a href="#">Page 1</a></li>
    <li><a href="#">Page 2</a></li>
    <li><a href="#">Page 3</a></li>
  </ul>
</nav>

<div class="container-fluid" style="height:1000px">
  <h1>Some text to enable scrolling</h1>
  <h1>Some text to enable scrolling</h1>
  <h1>Some text to enable scrolling</h1>
  <h1>Some text to enable scrolling</h1>
  <h1>Some text to enable scrolling</h1>
  <h1>Some text to enable scrolling</h1>
  <h1>Some text to enable scrolling</h1>
  <h1>Some text to enable scrolling</h1>
  <h1>Some text to enable scrolling</h1>
  <h1>Some text to enable scrolling</h1>
  <h1>Some text to enable scrolling</h1>
</div>

  1. 부착하려는 요소에 data-spy=”affix”를 추가

  2. 필요에 따라 data-offset-topbottom속성을 추가 하여 스크롤 위치를 계산해 추가하면 그 위치부터 부착됨

위의 첫 번째 예에서 Apprite 플러그인은 상단에서 197픽셀을 스크롤했을 때 .affix 클래스(position:fixed)를 <nav> 요소에 추가. 예를 열면 0의 값을 가진 CSS 최상위 속성을 .afix 클래스에 추가한 것도 볼 수 있음. 이렇게 하면 상단에서 197픽셀을 스크롤했을 때 탐색 막대가 항상 페이지 맨 위에 있어야 함.

Scrollspy & Affix

Horizontal Menu (Navbar)

<body data-spy="scroll" data-target=".navbar" data-offset="50">
