How Scrollspy works
<!-- [1] [2] [4](scrollable area) -->
<body data-spy="scroll" data-target=".navbar" data-offset="50">
<!-- [2] -->
<nav class="navbar navbar-inverse navbar-fixed-top">
...
<ul class="nav navbar-nav">
<!-- [3] -->
<li><a href="#section1">Section 1</a></li>
...
</nav>
<!-- [3] -->
<div id="section1">
<h1>Section 1</h1>
<p>Try to scroll this page and look at the navigation bar while scrolling!</p>
</div>

</body>
data-spy=”scroll” : 스크롤 가능 영역으로 사용해야하는 요소에 추가 (
body data-spy="scroll")스크롤 가능 영역에 있는(
body) data-target(.navbar) 의 ID 또는 클래스값이 있는 속성(nav)을 추가 (navbar가 스크롤 가능 영역과 연결되어 있는지 확인하는 것)navbar의 목록 항목에 있는 a 링크의 href값과 스크롤 가능한 요소의 ID와 일치해야함 (
<div id="section1"> = <a href="#section1">)선택적 data-offset속성은 스크롤 위치를 계산할 때 위에서 오프셋할 픽셀 수를 지정 (스크롤 가능한 요소로 이동할 때 탐색 모음 내부의 링크가 활성 상태를 너무 빨리 또는 너무 일찍 변경한다고 느낄 때 유용함, 기본값은 10 픽셀)
상대 위치 지정 필요 : data-spy = “scroll”이있는 요소가 제대로 작동하려면 값이 “relative”인 CSS 위치 속성이 필요 (
body position : relative)
