}기본적인 header를 만들었다면 JS를 이용해 스크롤 동작에 따라 css를 적용될 수 있도록 하기위해 스크롤 시에 sticky라는 class를 생성해 준다.
<script type="text/javascript">
window.addEventListener("scroll", function(){
var header = document.querySelector("header");
header.classList.toggle("sticky", window.scrollY > 0);
//Y축 방향으로 스크롤이 발생하면 sticky라는 class를 토글
})
</script>생성된 .sticky에 스타일을 적용해 준다.
header.sticky {
padding: 5px 100px;
background: #fff;
}
header.sticky ul li a, header.sticky .logo {
color: #000;
}결과
