Nav

Ba liens ya navigation ya Navbar etongami na ba .navoptions na biso na classe na bango moko ya modificateur mpe esengaka kosalela ba classes ya toggler mpo na styling ya réponse ya malamu. Navigation na ba navbars ekokola pe pona ko occuper espace horizontal ebele ndenge ekoki pona ko garder ba contenus ya navbar na yo na sécurité aligné.

Ba états .activeactifs —na —mpo na kolakisa lokasa ya lelo ekoki kosalelama mbala moko na .nav-links to baboti na bango ya penepene .nav-items.

<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">
