Azonao atao koa ny mampiasa dropdowns ao amin'ny navbaro. Ny menio midina dia mila singa famonosana ho an'ny fametrahana, koa aoka ho azo antoka ny hampiasa singa misaraka sy misy akany ho an'ny .nav-itemsy .nav-linkaraka ny aseho eto ambany.

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

      </ul>
    </div>

teny

Asio fanaraha-maso sy singa isan-karazany ao anaty navbar:

<nav class="navbar navbar-light bg-light">
  <div class="container-fluid">
    <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>

Ireo singa ankizy avy hatrany amin'ny .navbarfampiasana fandrindrana flex ary ho default amin'ny justify-content: space-between. Mampiasà fitaovana flex fanampiny raha ilaina hanitsiana io fihetsika io.

<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>
    </form>
  </div>
</nav>

Miasa ihany koa ny vondrona fampidirana. Raha endrika iray manontolo na endrika iray ny navbar-nao, dia azonao atao ny mampiasa ilay <form>singa ho fitoeran-javatra ary mitahiry HTML sasany.

<nav class="navbar navbar-light bg-light">
  <form class="container-fluid">
    <div class="input-group">
      <span class="input-group-text" id="basic-addon1">@</span>
      <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="basic-addon1">
    </div>
  </form>
</nav>

Ny bokotra isan-karazany dia tohanana ao anatin'ireo endrika navbar ireo ihany koa. Fampahatsiahivana lehibe ihany koa izany fa ny fitaovana fampifanarahana mitsangana dia azo ampiasaina hampifanaraka ireo singa samihafa.

<nav class="navbar navbar-light bg-light">
  <form class="container-fluid justify-content-start">
    <button class="btn btn-outline-success me-2" type="button">Main button</button>
    <button class="btn btn-sm btn-outline-secondary" type="button">Smaller button</button>
  </form>
</nav>

Text

Navbars dia mety ahitana sombin-tsoratra miaraka amin'ny fanampian'ny .navbar-text. Ity kilasy ity dia manitsy ny firindrana mitsangana sy ny elanelana marindrano ho an'ny tady lahatsoratra.

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

Afangaro ary ampifanaraho amin'ny singa sy fitaovana hafa raha ilaina.

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Navbar w/ text</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarText" aria-controls="navbarText" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarText">
      <ul class="navbar-nav me-auto mb-2 mb-lg-0">
        <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="#">Features</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="#">Pricing</a>
        </li>
      </ul>
      <span class="navbar-text">
        Navbar text with an inline element
      </span>
    </div>
  </div>
</nav>

Tetika loko

Ny fametrahana ny navbar dia tsy mora kokoa noho ny fampifangaroana kilasy sy kojakoja momba ny lohahevitra background-color. Misafidiana amin'ny .navbar-lightfampiasana loko maivana, na .navbar-darkho an'ny loko maizina. Avy eo, ampifanaraho amin'ny .bg-*utility.

<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>

fitoeran

Na dia tsy ilaina aza izany dia azonao atao ny mametaka navbar iray .containermba hampifantoka azy amin'ny pejy iray–na dia mariho fa mbola ilaina ny fitoeran-javatra anatiny. Na azonao atao ny manampy kaontenera ao anatiny .navbarmba hampifantoka ny votoatin'ny navbar ambony raikitra na static .

<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>

Ampiasao ny iray amin'ireo kaontenera mandray andraikitra hanovana ny haben'ny votoatin'ny navbaro.

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

fametrahana

Ampiasao ny fampiasanay toerana hametrahana ny navbar amin'ny toerana tsy mitongilana. Misafidiana avy amin'ny raikitra mankany ambony, raikitra mankany ambany, na mipetaka amin'ny tampony (horonana miaraka amin'ny pejy mandra-pahatongany eny ambony, dia mijanona eo). Navbars raikitra dia mampiasa position: fixed, midika izany fa nesorina tamin'ny fikorianan'ny DOM mahazatra izy ireo ary mety mitaky CSS manokana (oh, padding-topeo amin'ny <body>) mba hisorohana ny fifandonana amin'ny singa hafa.

Mariho ihany koa fa ny .sticky-topfampiasana position: sticky, izay tsy tohanana tanteraka amin'ny navigateur rehetra .

<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>

Scralling

Ampio .navbar-nav-scrollamin'ny .navbar-nav(na zana-tsipìka navbar hafa) mba ahafahana mivezivezy mitsangana ao anatin'ny atiny azo toggle amin'ny navbar nirodana. Amin'ny alàlan'ny default, miditra amin'ny 75vh(na 75% amin'ny haavon'ny viewport) ny horonan-taratasy, saingy azonao atao ny manafoana izany amin'ny fananana CSS eo an-toerana --bs-navbar-heightna fomba fanao mahazatra. Any amin'ny seranan-tsambo lehibe kokoa rehefa mivelatra ny navbar dia hiseho toy ny ao amin'ny navbar mahazatra ny atiny.

Mariho fa ity fihetsika ity dia miaraka amin'ny mety ho tsy fahampian'ny overflow-rehefa mametraka overflow-y: auto(ilaina ny manodina ny atiny eto), overflow-xdia mitovy amin'ny auto, izay hanapaka votoaty marindrano.

Ity misy ohatra navbar mampiasa .navbar-nav-scrollmiaraka amin'ny style="--bs-scroll-height: 100px;", miaraka amin'ny fampiasana margin fanampiny ho an'ny elanelana tsara indrindra.

<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">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>

Fihetsika mamaly

Ny Navbars dia afaka mampiasa .navbar-toggler, .navbar-collapse, ary .navbar-expand{-sm|-md|-lg|-xl|-xxl}kilasy hamaritana hoe rahoviana ny atiny no mirodana ao ambadiky ny bokotra iray. Miaraka amin'ny fitaovana hafa, azonao atao ny misafidy mora foana ny fotoana hanehoana na hanafenana singa manokana.

Ho an'ny navbar izay tsy mirodana mihitsy, ampio ny .navbar-expandkilasy amin'ny navbar. Ho an'ny navbar izay mirodana foana, aza ampiana .navbar-expandkilasy.

Toggler

Navbar togglers dia miankavia amin'ny alàlan'ny default, fa raha manaraka singa iray amin'ny mpiray tam-po toy ny a .navbar-brand, dia ho tonga amin'ny farany havanana izy ireo. Ny famadihana ny marikao dia hampivadika ny fametrahana ny toggler. Ireto ambany ireto ny ohatra amin'ny karazana toggle samihafa.

Tsy .navbar-brandaseho amin'ny teboka faran'izay kely indrindra:

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

Indraindray ianao te-hampiasa ny plugin collapse hanetsika singa fitoeran-javatra ho an'ny atiny izay mipetraka ivelan'ny .navbar. Satria miasa amin'ny idsy data-bs-targetmifanandrify ny plugin-nay, dia vita izany!

Collapsed content

Toggleable via the navbar brand.

<div class="collapse" id="navbarToggleExternalContent">
  <div class="bg-dark p-4">
    <h5 class="text-white h4">Collapsed content</h5>
    <span class="text-muted">Toggleable via the navbar brand.</span>
  </div>
</div>
<nav class="navbar navbar-dark bg-dark">
  <div class="container-fluid">
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarToggleExternalContent" aria-controls="navbarToggleExternalContent" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
  </div>
</nav>

Rehefa manao izany ianao dia manoro hevitra ny hampidirana JavaScript fanampiny mba hamindra ny fifantohana amin'ny programa amin'ny fitoeran-javatra rehefa misokatra. Raha tsy izany, dia mety ho sarotra amin'ny mpampiasa klavier sy ny mpampiasa ny teknolojia manampy ny fitadiavana ny atiny vao nambara - indrindra raha ny fitoeran'entana nosokafana dia tonga alohan'ny mpanodina ao amin'ny firafitry ny antontan-taratasy. Manoro hevitra ihany koa izahay mba hahazoana antoka fa manana ny aria-controlstoetra ny toggler, manondro ny idfitoeran'ny atiny. Amin'ny teoria dia ahafahan'ny mpampiasa teknolojia manampy hitsambikina mivantana avy amin'ny toggler mankany amin'ny fitoeran-javatra feheziny izany-saingy tsy misy dikany ny fanohanana izany amin'izao fotoana izao.
