Ma kēia ʻaoʻao

Pehea e hana ai

Eia ka mea e pono ai ʻoe e ʻike ma mua o ka hoʻomaka ʻana me ka navbar:

Pono nā Navbars i kahi kāʻei .navbarme .navbar-expand{-sm|-md|-lg|-xl|-xxl}nā papa hāʻule pane a me nā papa kala .
ʻO nā Navbars a me kā lākou mau ʻike he wai ma ka paʻamau. E hoʻololi i ka ipu e kaupalena i ko lākou ākea ākea ma nā ʻano like ʻole.
E hoʻohana i kā mākou papa hana hoʻokaʻawale a hoʻololi no ka hoʻomalu ʻana i ka spacing a me ke kaulike ʻana i loko o nā navbars .
Hoʻololi nā Navbars ma ka maʻamau, akā hiki iā ʻoe ke hoʻololi maʻalahi iā lākou e hoʻololi i kēlā. ʻO ke ʻano pane e pili ana i kā mākou Collapse JavaScript plugin.
E hōʻoia i ka loaʻa ʻana ma o ka hoʻohana ʻana i kahi <nav>mea a i ʻole, inā e hoʻohana ana i kahi mea maʻamau e like me ka <div>, e hoʻohui i kahi role="navigation"i kēlā me kēia navbar e hoʻomaopopo maopopo iā ia he ʻāina ʻāina no nā mea hoʻohana i nā ʻenehana kōkua.
E hōʻike i ka mea o kēia manawa ma ka hoʻohana ʻana aria-current="page"no ka ʻaoʻao o kēia manawa a i ʻole aria-current="true"ka mea i kēia manawa i kahi set.
Mea hou ma v5.2.0: Hiki ke hoʻohālikelike ʻia nā Navbars me nā mea hoʻololi CSS i hoʻopili ʻia i ka .navbarpapa kumu. .navbar-lightua hoʻopau ʻia a .navbar-darkua kākau hou ʻia e kāpae i nā mea hoʻololi CSS ma mua o ka hoʻohui ʻana i nā kaila hou.

ʻO ka hopena animation o kēia māhele e pili ana i ka prefers-reduced-motionnīnau media. E ʻike i ka ʻāpana hoʻohaʻahaʻa o kā mākou palapala hiki ke komo .

Maʻiʻo i kākoʻo ʻia

Hele mai nā Navbars me ke kākoʻo i kūkulu ʻia no ka liʻiliʻi o nā ʻāpana. E koho mai i ka mea e pono ai:

.navbar-brandno kāu hui, huahana, a i ʻole inoa papahana.
.navbar-navno ka hoʻokele piha kiʻekiʻe a me ka māmā (me ke kākoʻo no nā hāʻule iho).
.navbar-togglerno ka hoʻohana ʻana me kā mākou plugin collapse a me nā ʻano hoʻokele hoʻokele ʻē aʻe .
Hoʻololi a me ka hoʻokaʻawale ʻana i nā pono no kēlā me kēia ʻano kaohi a me nā hana.
.navbar-textno ka hoʻohui ʻana i nā kaula kikoʻī o ka kikokikona.
.collapse.navbar-collapseno ka hui pū ʻana a me ka hūnā ʻana i nā maʻiʻo o ka navbar e kahi ʻāpana makua.
E hoʻohui i kahi koho .navbar-scrolle hoʻonoho i kahi max-heightmaʻiʻo navbar i hoʻonui ʻia .

Eia kekahi laʻana o nā ʻāpana ʻāpana āpau i hoʻokomo ʻia i loko o kahi navbar hoʻonaʻauao māmā e hāʻule ʻakomi i ka wahi haʻi lg(nui).

Maʻiʻo waho

I kekahi manawa makemake ʻoe e hoʻohana i ka plugin collapse e hoʻomaka i kahi mea pahu no ka ʻike e noho ana ma waho o ka .navbar. No ka mea e hana ana kā mākou plugin i ka ida me ka data-bs-targethoʻohālikelike ʻana, maʻalahi ia hana!

Maʻiʻo hāʻule

Hiki ke hoʻololi ʻia ma o ka brand navbar.

Ke hana ʻoe i kēia, manaʻo mākou e hoʻokomo i ka JavaScript hou e hoʻoneʻe i ka manaʻo programmatically i ka ipu ke wehe ʻia. A i ʻole, paʻakikī paha nā mea hoʻohana keyboard a me nā mea hoʻohana i nā ʻenehana kōkua i ka ʻimi ʻana i ka ʻike hou i hōʻike ʻia - ʻoiai inā ʻo ka ipu i wehe ʻia ma mua o ka mea hoʻololi i ke ʻano o ka palapala. Manaʻo pū mākou e hōʻoia i ka mea hoʻololi i ke ʻano aria-controls, e kuhikuhi ana i ka idpahu maʻiʻo. Ma ke kumumanaʻo, ʻae kēia i nā mea hoʻohana ʻenehana kōkua e lele pololei mai ka toggler a i ka ipu āna e hoʻomalu ai - akā paʻakikī ke kākoʻo no kēia.

Offcanvas

E hoʻololi i kāu navbar e hoʻonui ana a e hāʻule ana i loko o kahi pahu huki waho me ka ʻāpana offcanvas . Hoʻonui mākou i nā ʻano paʻamau offcanvas a hoʻohana i kā mākou .navbar-expand-*papa e hana i kahi ʻaoʻao hoʻokele ikaika a maʻalahi.

Ma ka laʻana ma lalo nei, no ka hana ʻana i kahi navbar offcanvas i hāʻule mau ma nā wahi haʻi āpau, e haʻalele i ka .navbar-expand-*papa.
