Navbar
Sgrìobhainnean agus eisimpleirean airson bann-cinn seòlaidh cumhachdach, freagairteach Bootstrap, an navbar. A’ toirt a-steach taic airson branndadh, seòladh, agus barrachd, a’ toirt a-steach taic don plugan tuiteam againn.
Mar a tha e ag obair
Seo na dh’ fheumas tu a bhith eòlach mus tòisich thu leis a’ bhàr nav:
- Feumaidh navbars còmhdach
.navbar
le.navbar-expand{-sm|-md|-lg|-xl|-xxl}
airson tuiteam freagairteach agus clasaichean sgeama dathan . - Tha navbars agus an susbaint siùbhlach gu bunaiteach. Atharraich an soitheach gus an leud còmhnard aca a chuingealachadh ann an diofar dhòighean.
- Cleachd na clasaichean farsaingeachd agus goireas sùbailte againn airson smachd a chumail air farsaingeachd agus co-thaobhadh taobh a-staigh na bàraichean seòlaidh.
- Tha navbars freagairteach gu bunaiteach, ach is urrainn dhut an atharrachadh gu furasta gus sin atharrachadh. Tha giùlan ciallach an urra ris a’ plugan Collapse JavaScript againn.
- Dèan cinnteach gum bi ruigsinneachd ann le bhith a’ cleachdadh
<nav>
eileamaid no, ma tha thu a’ cleachdadh eileamaid nas gnèitheach leithid<div>
, cuir a risrole="navigation"
a h-uile bàr seòlaidh gus a chomharrachadh gu soilleir mar sgìre shònraichte airson luchd-cleachdaidh teicneòlasan cuideachaidh. - Sònraich an rud làithreach le bhith a’ cleachdadh
aria-current="page"
airson na duilleige làithreach noaria-current="true"
airson an rud làithreach ann an seata.

earrann gluasad lùghdaichte de na sgrìobhainnean ruigsinneachd againn .
Susbaint le taic
Bidh Navbars a’ tighinn le taic togte airson dòrlach de fo-phàirtean. Tagh bho na leanas mar a dh 'fheumar:
.navbar-brand
airson do chompanaidh, toradh no ainm pròiseict..navbar-nav
airson seòladh làn-àirde agus aotrom (a’ toirt a-steach taic airson dropdowns)..navbar-toggler
airson a chleachdadh leis a’ plugan tuiteam againn agus giùlan toggling seòlaidh eile.- Goireasan sùbailte agus farsaingeachd airson smachdan agus gnìomhan cruth sam bith.
.navbar-text
airson sreathan teacsa le fòcas dìreach a chur ris..collapse.navbar-collapse
airson a bhith a’ cruinneachadh agus a’ falach susbaint navbar le briseadh pàrant.- Cuir roghainn a-steach
.navbar-scroll
gus susbaint bàr seòlaidh leudaichte a shuidheachadhmax-height
agus scrollaich .
Seo eisimpleir de na fo-phàirtean gu lèir a tha air an toirt a-steach do bhàr seòlaidh freagairteach le cuspair solais a thuiteas gu fèin-ghluasadach aig an lg
àite brisidh (mòr).

Bidh an eisimpleir seo a’ cleachdadh cùl -fhiosrachadh ( bg-light
) agus farsaingeachd ( my-2
, my-lg-0
, me-sm-0
, my-sm-0
) clasaichean goireis.
Brand
Faodar .navbar-brand
an cur an sàs anns a’ mhòr-chuid de na h-eileamaidean, ach tha acair ag obair as fheàrr, oir is dòcha gu feum cuid de na h-eileamaidean clasaichean goireis no stoidhlichean àbhaisteach.
Teacs
Cuir do theacsa taobh a-staigh eileamaid leis a’ .navbar-brand
chlas.

Nav
Bidh ceanglaichean seòlaidh Navbar a’ togail air na .nav
roghainnean againn leis a’ chlas atharrachaidh aca fhèin agus feumaidh iad clasaichean toggler a chleachdadh airson stoidhle freagairteach ceart. Bidh seòladh ann am bàraichean seòlaidh cuideachd a’ fàs gus a bhith a’ gabhail thairis na h-uimhir de dh’ àite còmhnard ’s as urrainn gus susbaint do bhàr-seòlaidh a chumail ceangailte gu tèarainte.
Cuir ris a’ .active
chlas .nav-link
gus an duilleag làithreach a chomharrachadh.
Thoir an aire gum bu chòir dhut cuideachd am aria-current
feart a chuir ris an fhaidhle gnìomhach .nav-link
.

Agus leis gu bheil sinn a’ cleachdadh chlasaichean airson ar seòladairean, faodaidh tu an dòigh-obrach stèidhichte air liosta a sheachnadh gu tur ma thogras tu.

Faodaidh tu cuideachd dropdowns a chleachdadh anns a’ bhàr seòlaidh agad. Feumaidh clàir tuiteam-sìos eileamaid còmhdaich airson a shuidheachadh, mar sin bi cinnteach gun cleachd thu eileamaidean fa leth agus neadachaidh airson .nav-item
agus .nav-link
mar a chithear gu h-ìosal.

Foirmean
Cuir diofar smachdan cruth agus co-phàirtean taobh a-staigh bàr nav:
<nav class="navbar navbar-light bg-light">
<div class="container-fluid">
<form class="d-flex">
<input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
<button class="btn btn-outline-success" type="submit">Search</button>
</form>
</div>
</nav>
Bidh clann sa bhad a’ .navbar
cleachdadh cruth sùbailte agus bidh iad bunaiteach gu justify-content: space-between
. Cleachd goireasan sùbailte a bharrachd mar a dh’ fheumar gus an giùlan seo atharrachadh.
<nav class="navbar navbar-light bg-light">
<div class="container-fluid">
<a class="navbar-brand">Navbar</a>
<form class="d-flex">
<input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
<button class="btn btn-outline-success" type="submit">Search</button>
</form>
</div>
</nav>
Bidh buidhnean cuir a-steach ag obair cuideachd. Mas e foirm slàn a th’ anns a’ bhàr seòlaidh agad, no foirm sa mhòr-chuid, faodaidh tu an <form>
eileamaid a chleachdadh mar shoitheach agus sàbhail beagan HTML.
<nav class="navbar navbar-light bg-light">
<form class="container-fluid">
<div class="input-group">
<span class="input-group-text" id="basic-addon1">@</span>
<input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="basic-addon1">
</div>
</form>
</nav>
Tha grunn phutanan a’ faighinn taic mar phàirt de na foirmean navbar sin cuideachd. Tha seo cuideachd na dheagh chuimhneachan gum faodar goireasan co-thaobhadh dìreach a chleachdadh gus eileamaidean de dhiofar mheudan a cho-thaobhadh.
<nav class="navbar navbar-light bg-light">
<form class="container-fluid justify-content-start">
<button class="btn btn-outline-success me-2" type="button">Main button</button>
<button class="btn btn-sm btn-outline-secondary" type="button">Smaller button</button>
</form>
</nav>
Teacs
Faodaidh pìosan teacsa a bhith ann an Navbars le cuideachadh bho .navbar-text
. Bidh an clas seo ag atharrachadh co-thaobhadh dìreach agus farsaingeachd chòmhnard airson sreathan teacsa.
<nav class="navbar navbar-light bg-light">
<div class="container-fluid">
<span class="navbar-text">
Navbar text with an inline element

Measgaich agus maids le co-phàirtean agus goireasan eile mar a dh’ fheumar.

Sgeama dathan
Cha robh e a-riamh cho furasta a bhith ag obair air a’ bhàr nav le taing don mheasgachadh de chlasaichean cuspaireil agus background-color
goireasan. Tagh bho .navbar-light
airson a chleachdadh le dathan cùl-raon aotrom, no .navbar-dark
airson dathan cùl-raoin dorcha. An uairsin, gnàthaich le .bg-*
goireasan.
<nav class="navbar navbar-dark bg-dark">
<!-- Navbar content -->
</nav>
<nav class="navbar navbar-dark bg-primary">
<!-- Navbar content -->
</nav>
<nav class="navbar navbar-light" style="background-color: #e3f2fd;">
<!-- Navbar content -->
</nav>
Gabhadairean
Ged nach eil feum air, faodaidh tu bàr-seòlaidh a phasgadh ann an .container
duilleag gus a mheadhanachadh - ged a thoir an aire gu bheil feum air soitheach a-staigh fhathast. No faodaidh tu soitheach a chuir a-steach .navbar
don ionad gus susbaint bàr-seòlaidh mullach stèidhichte no statach a-mhàin .
<div class="container">
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<div class="container-fluid">
<a class="navbar-brand" href="#">Navbar</a>
</div>
</nav>
</div>
Cleachd gin de na soithichean freagairteach gus atharrachadh dè cho farsaing ‘s a tha an susbaint anns a’ bhàr seòlaidh agad air a thaisbeanadh.
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<div class="container-md">
<a class="navbar-brand" href="#">Navbar</a>
</div>
</nav>
Suidheachadh
Cleachd na goireasan suidheachaidh againn gus navbars a chuir ann an suidheachaidhean neo-statach. Tagh bho bhith stèidhichte gu mullach, stèidhichte aig a’ bhonn, no steigte chun mhullach (sgrolaich leis an duilleag gus an ruig e am mullach, an uairsin fuirich ann). Bidh navbars stèidhichte a’ cleachdadh position: fixed
, a’ ciallachadh gu bheil iad air an tarraing bho shruth àbhaisteach an DOM agus is dòcha gu feum iad CSS àbhaisteach (me, padding-top
air an <body>
) gus casg a chuir air tar-tharraing le eileamaidean eile.
Thoir an aire cuideachd gu bheil .sticky-top
cleachdadh position: sticky
, nach eil a’ faighinn làn thaic anns a h-uile brobhsair .
<nav class="navbar navbar-light bg-light">
<div class="container-fluid">
<a class="navbar-brand" href="#">Default</a>
</div>
</nav>
<nav class="navbar fixed-top navbar-light bg-light">
<div class="container-fluid">
<a class="navbar-brand" href="#">Fixed top</a>
</div>
</nav>
<nav class="navbar fixed-bottom navbar-light bg-light">
<div class="container-fluid">
<a class="navbar-brand" href="#">Fixed bottom</a>
</div>
</nav>
<nav class="navbar sticky-top navbar-light bg-light">
<div class="container-fluid">
<a class="navbar-brand" href="#">Sticky top</a>
</div>
</nav>
Sgrolaich
Cuir .navbar-nav-scroll
ri .navbar-nav
(no fo-phàirt navbar eile) gus scrollaidh dìreach a chomasachadh taobh a-staigh susbaint toggle ann am bàr-seòlaidh a thuit. Gu gnàthach, bidh scrollaidh a’ tòiseachadh aig 75vh
(no 75% de dh’ àirde an t-seallaidh), ach faodaidh tu a dhol thairis air sin le seilbh àbhaisteach CSS ionadail --bs-navbar-height
no stoidhlichean àbhaisteach. Aig puirt-seallaidh nas motha nuair a thèid am bàr seòlaidh a leudachadh, nochdaidh susbaint mar a tha e ann am bàr seòlaidh bunaiteach.
Thoir an aire gu bheil an giùlan seo a’ tighinn le tarraing air ais a dh’ fhaodadh a bhith ann - nuair a tha overflow
suidheachadh overflow-y: auto
(feumar an susbaint a sgrùdadh an seo), overflow-x
co-ionann ri auto
, a bheir bàrr air susbaint chòmhnard.
Seo eisimpleir navbar a’ cleachdadh .navbar-nav-scroll
le style="--bs-scroll-height: 100px;"
, le cuid de ghoireasan iomaill a bharrachd airson am farsaingeachd as fheàrr.
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<div class="container-fluid">
<a class="navbar-brand" href="#">Navbar scroll</a>

Giùlan freagairteach
Faodaidh Navbars .navbar-toggler
, .navbar-collapse
, agus .navbar-expand{-sm|-md|-lg|-xl|-xxl}
clasaichean a chleachdadh gus faighinn a-mach cuin a thuiteas an susbaint aca air cùl putan. Còmhla ri goireasan eile, faodaidh tu gu furasta taghadh cuin a sheallas tu no a chuireas tu am falach eileamaidean sònraichte.
Airson navbars nach tuit gu bràth, cuir a’ .navbar-expand
chlas air a’ bhàr nav. Airson navbars a bhios an-còmhnaidh a 'tuiteam, na cuir .navbar-expand
clas sam bith ris.
Togbhail
Tha toglaichean Navbar air an co-thaobhadh ris an taobh chlì a ghnàth, ach ma leanas iad eileamaid sibling mar a .navbar-brand
, bidh iad gu fèin-obrachail air an co-thaobhadh ris an fhìor làimh dheis. Ma chuireas tu do chomharradh air ais cuiridh sin cùl ri suidheachadh an toggler. Gu h-ìosal tha eisimpleirean de dhiofar stoidhlichean toggle.
Gun a bhith .navbar-brand

Susbaint bhon taobh a-muigh
Aig amannan bidh thu airson am plugan tuiteam a chleachdadh gus eileamaid soithich a bhrosnachadh airson susbaint a tha gu structarail na shuidhe taobh a-muigh an fhaidhle .navbar

agus a’ data-bs-target
maidseadh, tha sin furasta a dhèanamh!

Nuair a nì thu seo, tha sinn a’ moladh JavaScript a bharrachd a thoirt a-steach gus am fòcas a ghluasad gu prògramach chun ghobhar nuair a thèid fhosgladh. Rud eile, tha coltas ann gum bi ùine chruaidh aig luchd-cleachdaidh meur-chlàr agus luchd-cleachdaidh theicneòlasan cuideachaidh an t-susbaint ùr fhoillseachadh - gu sònraichte ma thig an soitheach a chaidh fhosgladh ron toggler ann an structar na sgrìobhainn. Tha sinn cuideachd a’ moladh dèanamh cinnteach gu bheil aria-controls
buadhan aig an toggler, a’ comharrachadh meud an id
t-soithich susbaint. Ann an teòiridh, leigidh seo le luchd-cleachdaidh teicneòlas cuideachaidh leum gu dìreach bhon toggler chun inneal a tha e a’ cumail smachd - ach tha taic airson seo gu math neo-chunbhalach an-dràsta.
