Navbar

Nā palapala a me nā hiʻohiʻona no ke poʻomanaʻo hoʻokele ikaika a Bootstrap, ka navbar. Loaʻa i ke kākoʻo no ka hōʻailona ʻana, ka hoʻokele ʻana, a me nā mea hou aku, me ke kākoʻo no kā mākou plugin collapse.

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}nā papa hāʻule pane a me nā papa kala .
ʻO nā Navbars a me kā lākou mau ʻike he wai ma ka paʻamau. E hoʻohana i nā pahu koho e kaupalena i ko lākou ākea ākea.
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.
Ua hūnā ʻia nā Navbars i ka wā e paʻi ai. E hoʻoikaika iā lākou e paʻi ʻia ma ka hoʻohui .d-printʻana i ka .navbar. E ʻike i ka papa hana hōʻike .
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 heluhelu no kahi laʻana a me ka papa inoa o nā ʻāpana i kākoʻo ʻia.

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 .
.form-inlineno nā ʻano mana 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.

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).
