부트스트랩에서 .nav와 .navbar의 차이점에 대한 자세한 설명

내비게이션 바는 Bootstrap 웹사이트의 훌륭한 기능이자 눈에 띄는 기능입니다. 탐색 모음은 앱이나 웹사이트 탐색 헤더의 반응형 기본 구성 요소 역할을 합니다. 탐색 모음은 모바일 뷰포트에서 축소되고 사용 가능한 뷰포트 너비가 증가함에 따라 수평으로 확장됩니다. Bootstrap 탐색 모음의 핵심에는 탐색 모음에 사이트 이름과 기본 탐색 정의 스타일이 포함되어 있습니다. 이 글은 주로 부트스트랩 내비게이션 바에 있는 .nav와 .navbar의 차이점에 대한 자세한 설명을 소개하고 있습니다. 편집자는 이것이 꽤 좋다고 생각합니다. 이제 여러분에게 공유하고 참고할 수 있기를 바랍니다.

1. ul과 li로 구성된 간단한 탐색:

<ul class="nav nav-pills justify-content-center bg-dark nav-dark">
    <li class="nav-item">
      <a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="nav-link">1</a>
    </li>
    <li class="nav-item">
      <a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="nav-link">2</a>
    </li>
    <li class="nav-item">
      <a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="nav-link">3</a>
    </li>
  </ul>

 

//解析：.nav .nav-item .nav-link表示ul li是导航——.nav-pills表示胶囊状导航——.bg-dark/.nav-dark表示黑底白字——.justify-content-center表示导航栏在浏览器上居中显示

은 브라우저에 다음과 같이 표시됩니다.

브라우저 창이 축소되면 다음과 같이 표시됩니다.

2. 탐색 표시줄 - < ;nav> 라벨의 Class="navbar navbar-expand-sm"——

의 class="navbar-nav"——

  3. 탐색 모음 축소

  창이 576px 미만인 경우 단순한 프로그래밍 세로가 아닙니다. 탐색; 버튼 버튼으로 표시됩니다. 탐색 링크 숨기기, 표시하려면 버튼을 클릭하세요.

  4. 검색 상자를 나타내는 양식을 탐색 모음에 추가합니다. [? ? ? ? ? 】

  그림과 같이 네비게이션 바의 폼을 오른쪽 정렬하여 가장 오른쪽으로 이동시키는 방법은 무엇인가요? ? ? ? ? float:eight도 작동합니다. .

  emmmm....위의 해결책을 알고 있습니다. 그리드 시스템을 사용하여 왼쪽에 ul과 li를, 오른쪽에 양식을 각각 배열한 다음 Float 형식을 추가합니다.

  코드는 다음과 같습니다.

  <p class="container-fluid">
    <p class="row">
      <!-- 导航栏 -->
      <nav class="navbar fixed-top navbar-expand-sm bg-dark navbar-dark">
        <p class="col-lg-4">
        <ul class="navbar-nav">
          <li class="nav-item">
            <a class="nav-link" href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >link1</a>
          </li>
          <li class="nav-item">
            <a class="nav-link" href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >link2</a>

  <!-- 导航栏表单与按钮 -->
      <p class="col-lg-8">
