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

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

Kōwhiria mai i te pūmau ki runga, ka mau ki raro, ka piri ranei ki runga (panuku me te wharangi tae noa ki runga, ka noho ki reira). Ka whakamahia e nga navbars position: fixed, ko te tikanga ka toia mai i te rere noa o te DOM ka hiahiatia he CSS ritenga (hei tauira, padding-topi runga i te <body>) kia kore ai e inaki ki etahi atu huānga.

Kia mahara ano ko .sticky-topnga whakamahinga position: sticky, kaore i te tino tautokona i ia kaitirotiro .

<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>

Tāpirihia .navbar-nav-scrollki tetahi .navbar-collapse(tetahi atu waahanga-iti ranei) kia taea ai te panuku poutū i roto i nga ihirangi takahuri o te pae whakaterenga kua tiango. Ma te taunoa, ka whana te panuku ki roto i te 75vh(75% ranei o te teitei tauranga tiro), engari ka taea e koe te whakakore i tera me nga momo raarangi, ritenga ritenga ranei. I nga tauranga tirohanga nui ake ina whakaroahia te paewhakatua, ka puta nga ihirangi penei i te pae whakaterenga taunoa.

Kia mahara ko tenei whanonga ka tae mai me te ngoikoretanga o te overflow—ka tautuhi overflow-y: auto(he mea tika kia panuku te ihirangi ki konei), overflow-xhe rite ki te auto, ka tapahia etahi ihirangi whakapae.

Anei tetahi tauira navbar e whakamahi ana .navbar-nav-scrollme te style="max-height: 100px;", me etahi taputapu taapiri taapiri mo te mokowhiti tino pai.

Ma te whakakotahi me etahi atu taputapu, ka taea e koe te whiriwhiri i te wa e whakaatu ai, e huna ana ranei i etahi waahanga.

Mo nga pae whakatere e kore e tiango, taapirihia te .navbar-expandkaraehe ki te pae whakatere. Mo nga pae whakatere ka tiango i nga wa katoa, kaua e taapirihia he .navbar-expandkaraehe.
