Nav

Navbar navigationis nexus in .navoptiones nostras aedificant cum suo proprio genere determinativo et usum toggler classium requirunt ad stylum proprium respondendi. Navigatio in navbaribus crescet etiam ad spatium horizontale occupandum quam maxime ad contenta navbarum tutanda conservanda.

Civitates activae - cum .activepagina hodierna indicantes directe applicari possunt ad .nav-links vel ad proximum parentem suum .nav-item.

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <a class="navbar-brand" href="#">Navbar</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>
  <div class="collapse navbar-collapse" id="navbarNav">
    <ul class="navbar-nav">
      <li class="nav-item active">
        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></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>

        <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
      </li>
    </ul>
  </div>
</nav>

Et quia classibus nostris utimur navigiis, potes indicem substructum omnino accedere, si lubet.

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <a class="navbar-brand" href="#">Navbar</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>
  <div class="collapse navbar-collapse" id="navbarNavAltMarkup">
    <div class="navbar-nav">
      <a class="nav-item nav-link active" href="#">Home <span class="sr-only">(current)</span></a>
      <a class="nav-item nav-link" href="#">Features</a>
      <a class="nav-item nav-link" href="#">Pricing</a>
      <a class="nav-item nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
    </div>
  </div>
</nav>

Etiam stillicidiis uti in navbaribus tuis potes. Menus dropdown requirunt elementum involuti pro positione, ita scito uti elementis separatis et nidificatis pro .nav-itemet .nav-linkut infra ostendetur.

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

      </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>
      <li class="nav-item dropdown">
        <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
          Dropdown link
        </a>
        <div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
          <a class="dropdown-item" href="#">Action</a>
          <a class="dropdown-item" href="#">Another action</a>
          <a class="dropdown-item" href="#">Something else here</a>
        </div>
      </li>
    </ul>
  </div>
</nav>

Formae

Pone varias formas controllata et composita intra navbar cum .form-inline.

<nav class="navbar navbar-light bg-light">
  <form class="form-inline">
    <input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
    <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
  </form>
</nav>

Pueri elementa immediata in .navbarusu extensionis flexae et voluntatis defectui sunt justify-content: space-between. Utere additional utilitates inflectere ut opus ad hunc agendi modum accommodent.

<nav class="navbar navbar-light bg-light">
  <a class="navbar-brand">Navbar</a>
  <form class="form-inline">
    <input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
    <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
  </form>
</nav>

Circuli input etiam laborant;

<nav class="navbar navbar-light bg-light">
  <form class="form-inline">
    <div class="input-group">
      <div class="input-group-prepend">
        <span class="input-group-text" id="basic-addon1">@</span>
      </div>
      <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="basic-addon1">
    </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">
  <form class="form-inline">
    <button class="btn btn-outline-success" type="button">Main button</button>
    <button class="btn btn-sm btn-outline-secondary" type="button">Smaller button</button>
  </form>
</nav>

Textum

Navbars particulas textus ope continere potest .navbar-text. Classis haec verticalem alignment et horizontalem spatii chordarum textuum accommodat.

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

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

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <a class="navbar-brand" href="#">Navbar w/ text</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-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 mr-auto">
      <li class="nav-item active">
        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></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>
</nav>

Color consilia

Lemma navbarum numquam facilius egit propter compositionem classes et background-colorutilitates earum. Elige ex .navbar-lightusu colorum levium colorum, vel .navbar-darkcolorum obscurorum colorum. Deinde mos cum .bg-*utilitate.

<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 requiritur, navbarem in .containerpagina involvere potes vel unum intra ad solum centrum contenta top navbar fixi seu statice addere .

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

Cum continens intra navbarum tuum est, eius color horizontalis sub punctorum interpunctionibus submovetur minor quam .navbar-expand{-sm|-md|-lg|-xl}classis tua. Hoc efficit ut ne duplices in commentatione super- spectorum inferiorum, cum navbarum tuum collapsum sit.

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

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

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

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

Responsivum se gerendi rationibus

Navbars uti possunt .navbar-toggler, .navbar-collapse, et .navbar-expand{-sm|-md|-lg|-xl}classes mutare cum contentus eorum post puga cecidit. 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.
