<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Navbar</a>

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Navbar</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">

            <li><a class="dropdown-item" href="#">Something else here</a></li>
          </ul>
        </li>

    <form class="d-flex">
      <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
      <button class="btn btn-outline-success" type="submit">Search</button>
    </form>
  </div>
</nav>

Elemen anak langsung .navbarnggunakake tata letak fleksibel lan bakal dadi standar kanggo justify-content: space-between. Gunakake utilitas fleksibel tambahan yen perlu kanggo nyetel prilaku iki.

<nav class="navbar navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand">Navbar</a>
    <form class="d-flex">
      <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
      <button class="btn btn-outline-success" type="submit">Search</button>

    <button class="btn btn-sm btn-outline-secondary" type="button">Smaller button</button>
  </form>
</nav>

Teks

Navbar bisa ngemot potongan teks kanthi bantuan .navbar-text. Kelas iki nyetel alignment vertikal lan spasi horisontal kanggo strings teks.

<nav class="navbar navbar-light bg-light">
  <div class="container-fluid">
    <span class="navbar-text">
      Navbar text with an inline element
    </span>
  </div>
</nav>

Nyampur lan cocog karo komponen lan keperluan liyane yen perlu.

<nav class="navbar navbar-expand-lg navbar-light bg-light">

          <a class="nav-link" href="#">Pricing</a>
        </li>
      </ul>
      <span class="navbar-text">
        Navbar text with an inline element
      </span>
    </div>
  </div>
</nav>

Skema warna

Theming navbar wis tau dadi luwih gampang thanks kanggo kombinasi kelas tema lan background-colorkeperluan. Pilih saka .navbar-lightkanggo nggunakake werna latar mburi cahya, utawa .navbar-darkkanggo werna latar mburi peteng. Banjur, setel karo .bg-*keperluan.

<nav class="navbar navbar-dark bg-dark">
  <!-- Navbar content -->
</nav>

<nav class="navbar navbar-dark bg-primary">
  <!-- Navbar content -->
</nav>

<nav class="navbar navbar-light" style="background-color: #e3f2fd;">
  <!-- Navbar content -->
</nav>

Wadhah

Sanajan ora dibutuhake, sampeyan bisa mbungkus navbar ing .containertengah-tengah ing sawijining kaca–sanajan elinga yen wadhah njero isih dibutuhake. Utawa sampeyan bisa nambah wadhah nang .navbarkanggo mung tengah isi navbar ndhuwur tetep utawa statis .

<div class="container">
  <nav class="navbar navbar-expand-lg navbar-light bg-light">
    <div class="container-fluid">
      <a class="navbar-brand" href="#">Navbar</a>
    </div>
  </nav>
</div>

Gunakake sembarang wadhah responsif kanggo ngganti ambane isi ing navbar sampeyan diwenehi.

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-md">
    <a class="navbar-brand" href="#">Navbar</a>
  </div>
</nav>

Panggonan

Gunakake utilitas posisi kita kanggo nyelehake navbar ing posisi non-statis. Pilih saka tetep menyang ndhuwur, tetep menyang ngisor, utawa nempel ing ndhuwur (gulung karo kaca nganti tekan ndhuwur, banjur tetep ana). Navbar tetep nggunakake position: fixed, tegese lagi ditarik saka aliran normal DOM lan mbutuhake CSS khusus (contone, padding-toping <body>) kanggo nyegah tumpang tindih karo unsur liyane.

Elinga uga .sticky-topnggunakake position: sticky, sing ora didhukung kanthi lengkap ing saben browser .

<nav class="navbar navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Default</a>
  </div>
</nav>

<nav class="navbar fixed-top navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Fixed top</a>
  </div>
</nav>

<nav class="navbar fixed-bottom navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Fixed bottom</a>
  </div>
</nav>

<nav class="navbar sticky-top navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Sticky top</a>
  </div>
</nav>

Nggulung

Tambah .navbar-nav-scrollmenyang .navbar-nav(utawa sub-komponen navbar liyane) kanggo ngaktifake nggulung vertikal ing isi toggleable saka navbar ambruk. Kanthi gawan, gulung mlebu ing 75vh(utawa 75% saka dhuwur viewport), nanging sampeyan bisa ngganti karo properti adat CSS lokal --bs-navbar-heightutawa gaya khusus. Ing viewport luwih gedhe nalika navbar ditambahi, isi bakal katon kaya ing navbar standar.

Wigati dimangerteni menawa prilaku iki ana kemungkinan overflowcacat - nalika nyetel overflow-y: auto(dibutuhake kanggo nggulung konten ing kene), overflow-xpadha karo auto, sing bakal ngethok sawetara konten horisontal.

Punika conto navbar nggunakake .navbar-nav-scrollkaro style="--bs-scroll-height: 100px;", karo sawetara keperluan margin ekstra kanggo spasi paling luweh.

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Navbar scroll</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarScroll" aria-controls="navbarScroll" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarScroll">
      <ul class="navbar-nav me-auto my-2 my-lg-0 navbar-nav-scroll" style="--bs-scroll-height: 100px;">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Link</a>
        </li>
        <li class="nav-item dropdown">
          <a class="nav-link dropdown-toggle" href="#" id="navbarScrollingDropdown" role="button" data-bs-toggle="dropdown" aria-expanded="false">
            Link
          </a>
          <ul class="dropdown-menu" aria-labelledby="navbarScrollingDropdown">
            <li><a class="dropdown-item" href="#">Action</a></li>
            <li><a class="dropdown-item" href="#">Another action</a></li>
            <li><hr class="dropdown-divider"></li>
            <li><a class="dropdown-item" href="#">Something else here</a></li>
          </ul>
        </li>
        <li class="nav-item">
          <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Link</a>
        </li>
      </ul>
      <form class="d-flex">
        <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
        <button class="btn btn-outline-success" type="submit">Search</button>
      </form>
    </div>
  </div>
</nav>

Tumindak responsif

Navbar bisa nggunakake .navbar-toggler, .navbar-collapse, lan .navbar-expand{-sm|-md|-lg|-xl|-xxl}kelas kanggo nemtokake nalika isine ambruk ing mburi tombol. Ing kombinasi karo keperluan liyane, sampeyan bisa kanthi gampang milih nalika nuduhake utawa ndhelikake unsur tartamtu.

Kanggo navbar sing ora tau ambruk, nambah .navbar-expandkelas ing navbar. Kanggo navbar sing tansah ambruk, ora nambah .navbar-expandkelas sembarang.

Toggler

Toggler Navbar didadekake siji kiwa minangka standar, nanging yen padha ngetutake unsur sedulur kaya a .navbar-brand, bakal kanthi otomatis didadekake siji ing sisih tengen. Mbalikake markup sampeyan bakal mbalikke panggonan toggler. Ing ngisor iki conto gaya toggle sing beda.
