Spinners
Léirigh staid luchtaithe comhpháirte nó leathanaigh le rothlóirí Bootstrap, tógtha go hiomlán le HTML, CSS, agus gan JavaScript.
Faoi
Is féidir “sreangóirí” Bootstrap a úsáid chun staid luchtaithe do thionscadail a thaispeáint. Níl siad tógtha ach le HTML agus CSS, rud a chiallaíonn nach bhfuil JavaScript ag teastáil uait chun iad a chruthú. Beidh roinnt JavaScript saincheaptha uait, áfach, chun a n-infheictheacht a scoránaigh. Is féidir a gcuma, a ailíniú, agus a méid a shaincheapadh go héasca lenár ranganna fóntais iontacha.
Chun críocha inrochtaineachta, cuimsíonn gach lódóir anseo role="status"
agus nead <span class="visually-hidden">Loading...</span>
.
prefers-reduced-motion
cheist na meán. Féach an
rannán tairiscint laghdaithe dár gcáipéisíocht inrochtaineachta .
Rothaí teorann
Bain úsáid as na rothlóirí teorann le haghaidh táscaire luchtaithe éadrom.
<div class="spinner-border" role="status">
<span class="visually-hidden">Loading...</span>
</div>
Dathanna
Úsáideann an rothlóir teorann currentColor
dá chuid border-color
, rud a chiallaíonn gur féidir leat an dath a shaincheapadh le fóntais datha téacs . Is féidir leat aon cheann dár bhfóntais datha téacs a úsáid ar an rothlóir caighdeánach.
<div class="spinner-border text-primary" role="status">
<span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-secondary" role="status">
<span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-success" role="status">
<span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-danger" role="status">
<span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-warning" role="status">
<span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-info" role="status">
<span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-border text-light" role="status">
<span class="visually-hidden">Loading...</span>

<div class="spinner-border text-dark" role="status">

border-color
fóntais? Sonraíonn gach rothlóir
transparent
teorann teorainn le haghaidh taobh amháin ar a laghad, agus mar sin
.border-{color}
sháródh fóntais é sin.
spinner ag fás
Mura bhfuil fonn ort rothlóir teorann, aistrigh chuig an rothlóir fáis. Cé nach ndéanann sé casadh go teicniúil, fásann sé arís agus arís eile!
<div class="spinner-grow" role="status">
<span class="visually-hidden">Loading...</span>
</div>
Arís eile, tógtar an rothlóir seo le currentColor
, ionas gur féidir leat a chuma a athrú go héasca le fóntais dath téacs . Anseo tá sé i gorm, chomh maith leis na leaganacha tacaithe.
<div class="spinner-grow text-primary" role="status">
<span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow text-secondary" role="status">
<span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow text-success" role="status">
<span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow text-danger" role="status">
<span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow text-warning" role="status">
<span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow text-info" role="status">
<span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow text-light" role="status">
<span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow text-dark" role="status">
<span class="visually-hidden">Loading...</span>
</div>
Ailíniú
Tógtar rothlóirí i Bootstrap le rem
s , currentColor
, agus display: inline-flex
. Ciallaíonn sé seo gur féidir iad a athrú go héasca, a dhathú agus a ailíniú go tapa.
Imeall
Bain úsáid as fóntais corrlaigh mar .m-5
spásáil éasca.
<div class="spinner-border m-5" role="status">
<span class="visually-hidden">Loading...</span>
</div>
Socrúchán
Úsáid fóntais flexbox , fóntais snámhphointe , nó fóntais ailínithe téacs chun rothlóirí a chur go díreach san áit a dteastaíonn uait iad in aon chás.
Flex
<div class="d-flex justify-content-center">
<div class="spinner-border" role="status">
<span class="visually-hidden">Loading...</span>
</div>
</div>
<div class="d-flex align-items-center">
<strong>Loading...</strong>
<div class="spinner-border ms-auto" role="status" aria-hidden="true"></div>
</div>
Snámháin
<div class="clearfix">
<div class="spinner-border float-end" role="status">
<span class="visually-hidden">Loading...</span>
</div>
</div>
Ailíniú téacs
<div class="text-center">
<div class="spinner-border" role="status">
<span class="visually-hidden">Loading...</span>
</div>
</div>
Méid
Cuir leis .spinner-border-sm
agus .spinner-grow-sm
chun rothlóir níos lú a dhéanamh ar féidir é a úsáid go tapa laistigh de chomhpháirteanna eile.
<div class="spinner-border spinner-border-sm" role="status">
<span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow spinner-grow-sm" role="status">
<span class="visually-hidden">Loading...</span>
</div>
Nó, bain úsáid as CSS saincheaptha nó stíleanna inlíne chun na toisí a athrú de réir mar is gá.
<div class="spinner-border" style="width: 3rem; height: 3rem;" role="status">
<span class="visually-hidden">Loading...</span>
</div>
<div class="spinner-grow" style="width: 3rem; height: 3rem;" role="status">
<span class="visually-hidden">Loading...</span>
</div>
Cnaipí
Úsáid rothlóirí laistigh de chnaipí chun a chur in iúl go bhfuil gníomh á phróiseáil nó ar siúl faoi láthair. Is féidir leat freisin an téacs a mhalartú amach as an eilimint rothlaithe agus úsáid a bhaint as téacs cnaipe de réir mar is gá.
