[코딩 초보 개발일지] 입문_04-3. css 작업물 만들기(백그라운드 네비)

아래와 같이 백그라운드 네비게이션을 만들자

<Step 01>

1. #header 에 백그라운드네비 생성

2. 넓이, 높이값, 색상 등 부여

3. position 으로 위치값 부여

 : header 하위이므로 header에 relative.

4. z-index로 층부여(서브메뉴 보이도록)

5. 제이쿼리 부여 전 display:none;

<Step 02>

 

1. 서브메뉴 전체가 hover 되도록 submenu 제이쿼리 수정

2. bgnav도 함께 hover 되도록 제이쿼리 수정

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
    <script>
        $(".nav>ul>li").mouseover(function(){
            $(".nav>ul>li").find(".submenu").stop().slideDown(200);
            $(".bgnav").stop().slideDown(200);
        });
        $(".nav>ul>li").mouseleave(function(){
            $(".nav>ul>li").find(".submenu").stop().slideUp(200);
            $(".bgnav").stop().slideUp(200);
        });
    </script>
