Ba éléments ya mwana ya mbala moko ya .navbarkosalela flex layout mpe ekozala par défaut na justify-content: space-between. Salelá ba utilitaires flex ya kobakisa soki esengeli mpo na kobongisa bizaleli oyo.

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

Ba récipients

Atako esengeli te, okoki kozinga navbar na a .containermpo na katikati na yango na lokasa–atako yeba ete eloko ya kati esengeli naino. To okoki kobakisa eloko moko na kati ya .navbarmpo na kotya kaka na katikati ya makambo oyo ezali na kati ya navbar ya likoló oyo ezali kotɛngatɛnga to oyo ezali kotɛngatɛnga te .

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

Botiami na esika

Salelá ba utilitaires na biso ya position mpo na kotia ba navbars na ba positions oyo ezali statique te. Poná kati na oyo ekangami na likoló, ekangami na nse, to ekangami na likoló (kosala défilement na lokasa tii ekokóma na likoló, na nsima etikalaka wana). Ba navbars fixes esalela position: fixed, elingi koloba ba bendami na flux normal ya DOM mpe ekoki kosenga CSS personnalisé (ndakisa, padding-topna <body>) mpo na kopekisa superposition na ba éléments mosusu.

Yeba mpe ete .sticky-topesalela position: sticky, oyo esimbami mobimba te na navigateur nyonso .

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

Na ndenge ya libela, kosala défilement ebandi na 75vh(to 75% ya bosanda ya esika ya kotala), kasi okoki koboya yango na propriété personnalisée ya CSS ya esika --bs-navbar-heightto ba styles personnalisés. Na ba viewports ya minene tango navbar epanzani, contenus ekobima ndenge esalemaka na navbar ya défaut.

Svp yeba que comportement oyo eza na inconvénient potentiel ya overflow—ntango setting overflow-y: auto(esengeli pona ko défiler contenus awa), overflow-xezali équivalent ya auto, oyo eko crop mua contenus horizontal.

Tala ndakisa navbar kosalela .navbar-nav-scrollna style="--bs-scroll-height: 100px;", na mwa ba utilitaires ya marge ya likolo mpo na espacement optimal.

Makambo ya libanda

Tango mosusu olingi kosalela plugin ya collapse mpo na ko déclencher élément ya conteneur mpo na contenus oyo structurellement efandi libanda ya .navbar. Po plugin na biso esalaka na idpe data-bs-targetmatching, yango esalemaka facilement!

<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>

Ntango ozali kosala bongo, tozali kolendisa yo otya JavaScript mosusu mpo na komema focus na ndenge ya programɛ na esika oyo batyaka biloko ntango ekofungwama. Soki te, basaleli ya klaviatware mpe basaleli ya mayele ya kosunga bakozala mbala mosusu na mokakatano mpo na koluka makambo oyo emonisami sika - mingimingi soki eloko oyo efungolamaki eyei liboso ya mobongisi-nzela na ebongiseli ya mokanda. Tosengi mpe kosala ete toggler ezala na aria-controlsattribut, kolakisa na idya conteneur ya contenus. Na théorie, yango epesaka nzela na basaleli ya tekiniki ya lisalisi mpo na kopumbwa mbala moko uta na toggler kino na conteneur oyo yango ezali kotambwisa–kasi lisungi mpo na oyo ezali na ntango oyo mpenza patchy.
