Documenta et exempla quomodo utendi partes navigationis includuntur Bootstrap.

In hac pagina

Basis nav

Navigatio praesto est in Bootstrap communem notam et stilum communem, a basi .navclassium ad civitates activas et debiles. Swap determinatio classes ad commutandum inter se stilum.

Basis .navpars cum flexbox aedificatur et fundamentum validum praebent ad omnes rationes navigationis componendas. Includit stylum quemdam vincit (ad operandum cum electronicis), quaedam ligamen ad fasciculum pro amplioribus locis hit, et stylos fundamentales debiles.

Pars basis .navnullum .activestatum includit. Classis exempla includunt, maxime ad demonstrandum hoc genus particulare stylum speciale non felis.

Status activus ad technologias adiuvandas deferat, aria-currentattributo utere — utens pagevalore paginae hodiernae vel trueitem in statuto currenti.

<ul class="nav">
  <li class="nav-item">
    <a class="nav-link active" aria-current="page" href="#">Active</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
  </li>
</ul>

Classes per totum adhibentur, ut signum tuum super flexibile esse possit. Utere <ul>s sicut supra, <ol>si ordo rerum tuarum interest, vel <nav>elementum tuum volve. Quia .navusus display: flex, nexus nav idem se gerere volunt ac nav res, sed sine notae extra.

<nav class="nav">
  <a class="nav-link active" aria-current="page" href="#">Active</a>
  <a class="nav-link" href="#">Link</a>
  <a class="nav-link" href="#">Link</a>
  <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
</nav>

Praesto styles

Mutare rationem .navcomponentium cum mutatis et utilitatibus. Misce et aequare prout opus est, vel aedificare tuum.

Noctis Horizontalis

Mutare alignment horizontalem nav cum flexbox utilitatibus . Defalta, navigiae permixtae sunt, sed facile eas ad centrum vel ad dextram aligned transmutare potes.

Sitas .justify-content-center:

<ul class="nav justify-content-center">
  <li class="nav-item">
    <a class="nav-link active" aria-current="page" href="#">Active</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
  </li>
</ul>

Dextra-aligned with .justify-content-end:

<ul class="nav justify-content-end">
  <li class="nav-item">
    <a class="nav-link active" aria-current="page" href="#">Active</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
  </li>
</ul>

Vertical

Navigationem tuam pone mutando flex item directionem cum .flex-columnutilitate. Eget eos ACERVUS in quibusdam viewports sed non aliis? Versionibus responsivis utere (exempli gratia .flex-sm-column).

<ul class="nav flex-column">
  <li class="nav-item">
    <a class="nav-link active" aria-current="page" href="#">Active</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
  </li>
</ul>

Ut semper, navigatio verticalis sine <ul>s quoque fieri potest.

<nav class="nav flex-column">
  <a class="nav-link active" aria-current="page" href="#">Active</a>
  <a class="nav-link" href="#">Link</a>
  <a class="nav-link" href="#">Link</a>
  <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
</nav>

Tabs

Nav superne fundamentalem accipit et addit .nav-tabsclassem ad interfacem tabbed generandam. Use them to create tabbable regions with our tab JavaScript plugin .

<ul class="nav nav-tabs">
  <li class="nav-item">
    <a class="nav-link active" aria-current="page" href="#">Active</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
  </li>
</ul>

Diripio

Accipe ipsum HTML, sed utere .nav-pillsloco:

<ul class="nav nav-pills">
  <li class="nav-item">
    <a class="nav-link active" aria-current="page" href="#">Active</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
  </li>
</ul>

Imple et iustifica

Coge .navcontenta tua extendere plenam latitudinem in promptu unum duorum generum determinatorum. Ut proportionaliter imple omnia spatia tua .nav-items, utere .nav-fill. Animadverte quod omne spatium horizontale occupatum est, sed non omne nav item latitudinem eandem habet.

<ul class="nav nav-pills nav-fill">
  <li class="nav-item">
    <a class="nav-link active" aria-current="page" href="#">Active</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Much longer nav link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
  </li>
</ul>

Cum navigatione subnixa utens <nav>, tuto praeterire potes .nav-itemquod solum ad elementa .nav-linkferendis requiritur .<a>

<nav class="nav nav-pills nav-fill">
  <a class="nav-link active" aria-current="page" href="#">Active</a>
  <a class="nav-link" href="#">Much longer nav link</a>
  <a class="nav-link" href="#">Link</a>
  <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
</nav>

Pro aequalibus elementis utere .nav-justified. Omne spatium horizontalis a nexus nav occupabitur, sed .nav-fillsupra dissimilis, omnis item navis latitudo eadem erit.

<ul class="nav nav-pills nav-justified">
  <li class="nav-item">
    <a class="nav-link active" aria-current="page" href="#">Active</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Much longer nav link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  <li class="nav-item">
    <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
  </li>
</ul>

Simili .nav-fillexemplo usus <nav>navigationis substructio.

<nav class="nav nav-pills nav-justified">
  <a class="nav-link active" aria-current="page" href="#">Active</a>
  <a class="nav-link" href="#">Much longer nav link</a>
  <a class="nav-link" href="#">Link</a>
  <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
</nav>

Opus inflectere utilitates

Si responsivas variationes nav opus est, considera utens seriem flexboxs utilitatum . Dum verbosius, hae utilitates maiorem customizationem dant per fractiones responsivas. In exemplo infra, nostra nav in puncto infimo iacebit, tum ad horizontem horizontalem accommodabit quae latitudinem praesto a parvo puncto incipientis implet.

<nav class="nav nav-pills flex-column flex-sm-row">
  <a class="flex-sm-fill text-sm-center nav-link active" aria-current="page" href="#">Active</a>
  <a class="flex-sm-fill text-sm-center nav-link" href="#">Longer nav link</a>
  <a class="flex-sm-fill text-sm-center nav-link" href="#">Link</a>
  <a class="flex-sm-fill text-sm-center nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
</nav>

De accessibility

Si navigiis ad vecturam navigationis uteris, scito te ad role="navigation"maxime logicum parentis vasi addere <ul>, vel <nav>elementum circa totam navigationem involvere. Munus ipsum non addas <ul>, quia hoc impediret quominus technologiae adiuvativae tamquam index actualis nuntiaretur.

Nota vectes navigationis, etiam si visibiliter dicuntur tabs cum .nav-tabsclasse, dari non debere role="tablist", role="tab"vel role="tabpanel"attributa. Hae tantum aptae sunt ad interfaces dynamicas tabbed, de quibus in WAI ARIA Auctoring Exercitia . Vide in hac sectione in sectione interfaces dynamicas mores JavaScript pro exemplo. Attributum aria-currentnon est necessarium in interfaces dynamicas tabbed cum JavaScript noster tractat statum electum addendo aria-selected="true"in tabe activa.

per dropdowns

Add dropdown menus with a little extra HTML and the dropdowns JavaScript plugin .

JavaScript mores

Utere tab JavaScript plugin-include eam singillatim vel per bootstrap.jsfasciculum compilatum — proferre tabs et pilulas nostras navigationis ad creandos panes tabu- lares contentorum localium.

Dynamica interfaces tabbed, de quibus in WAI ARIA Praefectis auctoribus, attributa require role="tablist", role="tab", role="tabpanel"et additamenta ut eorum structuram, functionem et statum hodiernum deferant technologiarum assistivorumaria- utentes (ut lectores ductiles). Pro praxi, <button>elementa pro tabs utentes commendamus, sicut hae potestates sunt quae mutationem dynamicam trigger, potius quam nexus qui ad novam paginam vel locum navigant.

Nota quod interfaces dynamicas non debet continere guttae menus, cum hoc causat quaestiones tam usabilitatis quam accessibilitatis. Ex prospectu usabili, quod nunc elementum felis tab's ostendi non statim visibile est (sicut in menu dropdown clausus est) confusionem movere potest. Ex parte accessibilitatis, nunc sensibilis modus non est ad describendam hanc modi constructionem ad exemplar WAI ARIA vexillum, quod significat non facile intellegi posse technologiae adiuvandae utentes.

Hoc est aliquis placeholder contentum domo tab's adiunctis contentis. Alter tab strepitando visibilitatem hanc pro altera toggle faciet. Tab JavaScript swaps classes ad moderandum visibilitatem et styling contentus. Ea uti potes cum tabs, pilis, et quibusvis aliis .navnavigationibus -powered.

Nota quod si usus <nav>es, directe ei non debes addere role="tablist", sicut hoc elementi munus proprium quasi terminus navigandi vincet.

Via JavaScript

Admitte tabbable tabs per JavaScript (singulis tab indiget ut singillatim reducitur);

var triggerTabList = [].slice.call(document.querySelectorAll('#myTab a'))
triggerTabList.forEach(function (triggerEl) {
  var tabTrigger = new bootstrap.Tab(triggerEl)

  triggerEl.addEventListener('click', function (event) {
    event.preventDefault()
    tabTrigger.show()
  })
})

Singula tab in pluribus modis movere potes:

var triggerEl = document.querySelector('#myTab a[href="#profile"]')
bootstrap.Tab.getInstance(triggerEl).show() // Select tab by name

var triggerFirstTabEl = document.querySelector('#myTab li:first-child a')
bootstrap.Tab.getInstance(triggerFirstTabEl).show() // Select first tab

Pade effectus

Ut tabescas in tabes, addas .fadesingulis .tab-pane. Prima tab pane debet etiam .showfacere ut initialis visibiles.
