[html] 고정 된 flexbox 탐색 메뉴 아래에 스크롤 가능한 컨텐츠 배치

다음 스 니펫 (전체 화면 모드로 볼 필요가 있음)이 있습니다. <main>요소를 요소 바로 아래 에 배치하려고합니다 <header>. 나는이 <header>나는 그것이의 콘텐츠를 통해 사용자가 스크롤로 화면 상단에 있고 싶어하기 때문에 고정 된 위치를 <main>요소입니다. 내가 아는 모든 것을 시도했지만 가장 좋은 방법은 <header>요소를 요소 위에 배치 <main>하여 내용의 큰 부분을 잘라내는 것입니다.

내가 찾은 가장 가까운 솔루션은 <main>요소 에 추측 된 상단 패딩을 배치하여를 지우는 것 <header>입니다. 그러나 px 대신 rem 크기 조정을 사용하기 때문에이 솔루션은 다양한 화면 크기를 잘 설명하지 못합니다. <header>상대 또는 백분율 기반 높이를 사용 하는 여러 요소를 내부에 배치하면 상단 패딩 아이디어가 더욱 악화됩니다 . 한 화면 크기에서는 모든 것이 완벽하게 정렬 될 수 있으며 다른 화면 크기에서는 내용이 사라질 수 있습니다.

마지막으로 jQuery를 사용하여 상단 패딩을 동적으로 설정할 수 있다는 것을 알고 있지만 항상 제대로 작동하지는 않습니다. 궁금한 점은 순수한 CSS / html 솔루션이 있다는 것입니다.

아무도 내가 여기서 잃어버린 것을 말해 줄 수 있습니까? 상단 패딩 방법이 유일하게 실행 가능한 솔루션입니까?

나는 같은 결과를 얻었지만 (내가 틀렸다면 나를 교정하십시오), js는 없습니다. 그리고 아래 내용에 의해 헤더 높이가 고려되는 것 같습니다.

주요 아이디어 – 포장하지 않는 <header>과에 적용 position: sticky, z-index필요하지도.

정확히 코드를 사용하지 않았지만 결과를 반복하려고했습니다. 문제에 대한 유용한 아이디어를 찾을 수 있기를 바랍니다.

화면 너비가 작고 메뉴를 토글하면 일부 답변의 코드가 기본 콘텐츠를 아래로 푸시합니다. 내 코드에는 해당 문제가 없습니다.

헤더를 줄 바꿈 할 필요가 없으므로 헤더 요소의 상위 2 개 div 컨테이너를 제거하십시오. 헤더 요소는 이미 컨테이너입니다.

height:200rem;머리글 스타일과 padding-top: 13rem or 5rem주요 요소 스타일을 제거하십시오 .

마지막으로 헤더 스타일의 위치 속성을 끈적 대신 absolute및 z 색인을 추가합니다.

이것은 일종의 거친 해킹이지만 문서 흐름에 남아있는 실제 헤더 뒤에 숨어있는 두 번째 헤더를 만들 수 있습니다. <main> .

헤더를 구성하는 요소를 복제하고 더 낮게 z-index설정하고에서 position: fixed로 전환하십시오 position: relative. 그런 다음 숨겨진 <header>요소 의 높이를 제거하고 padding-topfrom을 제거하십시오 <main>.

$(document).ready(function() {
  $('#navToggle').click(function() {
    $("div#bottom-container > nav").slideToggle();
  });

  $(window).resize(function() {
      if(window.innerWidth >= "751") {
          $("header > div#bottom-container > nav").show();
      }else {
          $("header > div#bottom-container > nav").hide();
      }
  });

  $("header > div#bottom-container > nav > ul > li > a").click(function(e) {
     if (window.innerWidth <= "750") {
       if ($(this).siblings().size() > 0) {
         e.preventDefault();
         $(this).siblings().slideToggle("slow");
      }
    }
  });

편집 : 나는 왜 내가 이것을 전에 생각하지 않았는지 모른다. 그냥 설정 #headwrap과 <main>에 position: relative. 그런 다음, 제거 height에 <main>와 세트 <body>에 display: flex와 flex-direction: column. 마지막으로의 내용을 <main>로 묶습니다 <div>.

여기에서는 스크롤을 보여주기 위해 div의 높이를 4000px로 설정했습니다.

$(document).ready(function() {
  $('#navToggle').click(function() {
    $("div#bottom-container > nav").slideToggle();
  });

  $(window).resize(function() {
      if(window.innerWidth >= "751") {
          $("header > div#bottom-container > nav").show();
      }else {
          $("header > div#bottom-container > nav").hide();
      }
  });

     if (window.innerWidth <= "750") {
       if ($(this).siblings().size() > 0) {
         e.preventDefault();
         $(this).siblings().slideToggle("slow");
      }
    }
  });

당신은 위치 를 찾고 있지 않습니까? 상단 : 0; ? 오른쪽 스크롤 할 때 사용자를 따르는 메뉴를 원하십니까? 그런 다음 # bottom-container 를 다음과 같이 변경하십시오 .

#bottom-container {
  display: flex;
  flex-direction: column;
  text-align: center;
  box-shadow: 2px 5px 10px 1px rgba(0, 0, 0, 0.55);
  position: sticky;
  top: 0;
  z-index: 1;
}

그리고 그게 전부라고 생각합니다. 그러나 하나는 확실합니다.이 구조를 어떻게 만들 었는지 다시 생각해야합니다. 지저분합니다. 다음과 같은 결과를 얻을 수 있습니다.

당신이 그것을 사용할 필요가 없다면 JS cuz도 없습니다. 이게 도움이 되길 바란다.

jQuery 대신 Vanilla-JavaScript를 제공 할 수 있습니다…

페이지가로드 될 때 (onload 이벤트) “header”의 크기를 가져 와서 “main”의 패딩에 추가하십시오.

window.addEventListener("load", function(e){
  my_main.style.paddingTop = my_header.clientHeight + "px";
}, 1);

작동하기 위해 “header”와 “main”요소에 “id”를 부여했습니다.

<header id="my_header"> <main id="my_main">

window.addEventListener("load", function(e){
  my_main.style.paddingTop = my_header.clientHeight + "px";
}, 1);
