      <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>

Pueri elementa immediata extensionis flexae .navbarutendi et deficere debent justify-content: space-between. Utere additional utilitates inflectere ut opus ad hunc agendi modum accommodent.

<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">

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

Variae globuli fulciuntur ut pars harum formarum navbarum quoque. Hoc etiam magnum est monumentum quod utilitates dam verticalis adhiberi possunt ad varias mediocritates ponendas.

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

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

Miscere et aequare cum aliis componentibus et utilitatibus prout opus est.

<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">

<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>

Continentes

Etsi non quaeritur, navbarem in .containerpagina ad centrum involvere potes—quamvis nota interiorem receptaculum adhuc requiri. .navbarVel vas in medio ad solum centrum contenta capitis navbar fixi seu statice addere potes .

<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>

Utere omnibus vasis responsivis ad mutandum quam late contentum in navbare tuo praebeatur.

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

Placement

Utere positione nostra utilitates ad collocandas navbares in positionibus non-staticis. Elige a summo ad fixa, vel ad imum fixa, vel in cacumen haerere (cum paginae cartulas usque ad summum pervenerit, ibi remanet). Usus navbarum fixum position: fixed, significantes se e normali fluxu domae trahi et consuetudo CSS (exempli gratia) requirere potest padding-topne <body>cum aliis elementis incidat.

Nota etiam .sticky-topusus position: sticky, qui non plene in omni navigatro sustentatur .

<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>

Scrolling

Adde .navbar-nav-scrolla .navbar-nav(vel aliis navbar sub-componentibus) ut volumen verticalem efficiat intra contenta toggleabilium navbaris collapsae. Defalta, scrolling calcibus in ad 75vh(vel 75% e regione prospecti altitudinis), sed vincire potes quod cum loci CSS consuetudine proprietatis --bs-navbar-heightvel stylorum consuetudinum. In amplioribus aspectibus cum navbar dilatetur, contentus apparebit sicut in defalta navbar.

Quaeso note hunc agendi modum cum potentiale incommodo — overflowcum occasu overflow-y: auto(requiritur hic ad librum contentum venire), overflow-xinstar est auto, quod aliqua contentum horizontalem carpet.

Hic est exemplum navbar utens .navbar-nav-scrollcum style="--bs-scroll-height: 100px;"aliquibus extra margine utilitatibus ad optimum spacing.

<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>

Responsivum se gerendi rationibus

Navbars uti possunt .navbar-toggler, .navbar-collapse, et .navbar-expand{-sm|-md|-lg|-xl|-xxl}classes determinare cum contenta sua post puga pyga collapsa sunt. Cum aliis utilitatibus coniuncti, facile eligere potes quando elementa particularia demonstrare vel abscondere.

Nam navbars qui nunquam concidunt, .navbar-expandclassem in navbar addunt. Navbars enim quae semper concidunt, nullam .navbar-expandclassem addunt.

Toggler

Navbar togglers per defaltam varius relictus est, sed si fratrem quasi elementum sequantur .navbar-brand, automatice ad ius tenus perpendentur. Aversando notam tuam retexam collocationem toggler. Infra exempla toggle stylorum diversorum sunt.
