Forbhreathnú

Bainimid úsáid as bloc mór de naisc nasctha le haghaidh ár leathanach, rud a fhágann go bhfuil naisc deacair a chailleann agus go héasca inscálaithe - go léir agus limistéir mhóra buailte á soláthar againn. Tógtar uimhriú le heilimintí liosta HTML ionas gur féidir le léitheoirí scáileáin líon na nasc atá ar fáil a fhógairt. Bain úsáid as eilimint timfhilleadh <nav>chun é a aithint mar mhír loingseoireachta do léitheoirí scáileáin agus teicneolaíochtaí cúnta eile.

Ina theannta sin, ós rud é gur dócha go mbeidh níos mó ná rannóg loingseoireachta amháin dá leithéid ag leathanaigh, moltar tuairisc a sholáthar aria-labelchun <nav>a chuspóir a léiriú. Mar shampla, má úsáidtear comhpháirt an leathanaigh chun nascleanúint a dhéanamh idir sraith torthaí cuardaigh, d’fhéadfadh lipéad cuí a bheith ar aria-label="Search results pages".

<nav aria-label="Page navigation example">
  <ul class="pagination">
    <li class="page-item"><a class="page-link" href="#">Previous</a></li>
    <li class="page-item"><a class="page-link" href="#">1</a></li>
    <li class="page-item"><a class="page-link" href="#">2</a></li>
    <li class="page-item"><a class="page-link" href="#">3</a></li>
    <li class="page-item"><a class="page-link" href="#">Next</a></li>
  </ul>
</nav>

Ag obair le deilbhíní

Ag iarraidh íocón nó siombail a úsáid in ionad an téacs le haghaidh roinnt nasc uimhriúcháin? Bí cinnte go soláthróidh tú tacaíocht cheart don léitheoir scáileáin le ariatréithe.

<nav aria-label="Page navigation example">
  <ul class="pagination">
    <li class="page-item">
      <a class="page-link" href="#" aria-label="Previous">
        <span aria-hidden="true">&laquo;</span>
      </a>
    </li>
    <li class="page-item"><a class="page-link" href="#">1</a></li>
    <li class="page-item"><a class="page-link" href="#">2</a></li>
    <li class="page-item"><a class="page-link" href="#">3</a></li>
    <li class="page-item">
      <a class="page-link" href="#" aria-label="Next">
        <span aria-hidden="true">&raquo;</span>
      </a>
    </li>
  </ul>
</nav>

Stáit faoi mhíchumas agus stáit ghníomhacha

Is féidir naisc uimhriúcháin a shaincheapadh do chúinsí éagsúla. Bain úsáid .disabledas naisc a bhfuil an chuma orthu nach féidir cliceáil orthu agus .activechun an leathanach reatha a léiriú.

Cé go n- .disabledúsáideann an rang pointer-events: nonechun iarracht a dhéanamh feidhmiúlacht naisc <a>s a dhíchumasú, níl an t-airí CSS sin caighdeánaithe fós agus níl sé freagrach as nascleanúint méarchláir. Mar sin, ba cheart duit tabindex="-1"naisc faoi mhíchumas a chur leis i gcónaí agus JavaScript saincheaptha a úsáid chun a bhfeidhmiúlacht a dhíchumasú go hiomlán.

<nav aria-label="...">
  <ul class="pagination">
    <li class="page-item disabled">
      <a class="page-link">Previous</a>
    </li>
    <li class="page-item"><a class="page-link" href="#">1</a></li>
    <li class="page-item active" aria-current="page">
      <a class="page-link" href="#">2</a>
    </li>
    <li class="page-item"><a class="page-link" href="#">3</a></li>
    <li class="page-item">
      <a class="page-link" href="#">Next</a>
    </li>
  </ul>
</nav>

Is féidir leat ancairí gníomhacha nó díchumasaithe a mhalartú go roghnach le haghaidh <span>, nó an t-ancaire a fhágáil ar lár i gcás na saigheada roimhe seo agus na saigheada seo chugainn, chun feidhm chliceáil a bhaint agus fócas an mhéarchláir a chosc agus na stíleanna atá beartaithe a choinneáil.

<nav aria-label="...">
  <ul class="pagination">
    <li class="page-item disabled">
      <span class="page-link">Previous</span>
    </li>
    <li class="page-item"><a class="page-link" href="#">1</a></li>
    <li class="page-item active" aria-current="page">
      <span class="page-link">2</span>
    </li>
    <li class="page-item"><a class="page-link" href="#">3</a></li>
    <li class="page-item">
      <a class="page-link" href="#">Next</a>
    </li>
  </ul>
</nav>

Sizing

An bhfuil fonn ort uimhriú níos mó nó níos lú? Cuir .pagination-lgnó .pagination-smle haghaidh méideanna breise.

<nav aria-label="...">
  <ul class="pagination pagination-lg">
    <li class="page-item active" aria-current="page">
      <span class="page-link">1</span>
    </li>
    <li class="page-item"><a class="page-link" href="#">2</a></li>
    <li class="page-item"><a class="page-link" href="#">3</a></li>
  </ul>
</nav>

<nav aria-label="...">
  <ul class="pagination pagination-sm">
    <li class="page-item active" aria-current="page">
      <span class="page-link">1</span>
    </li>
    <li class="page-item"><a class="page-link" href="#">2</a></li>
    <li class="page-item"><a class="page-link" href="#">3</a></li>
  </ul>
</nav>

Ailíniú

Athraigh ailíniú na gcomhpháirteanna uimhriúcháin le fóntais flexbox .
