Conas a oibríonn sé

Tógtar comhpháirteanna dul chun cinn le dhá eilimint HTML, roinnt CSS chun an leithead a shocrú, agus cúpla tréithe. Ní úsáidimid an eilimint HTML5<progress> , ag cinntiú gur féidir leat barraí dul chun cinn a chruachadh, iad a bheochan agus lipéid téacs a chur os a gcionn.

Bainimid úsáid as .progressmar fhillteán chun uasluach an bharra dul chun cinn a léiriú.
Bainimid úsáid as an taobh istigh .progress-barchun an dul chun cinn go dtí seo a chur in iúl.
Teastaíonn .progress-barstíl inlíne, rang fóntais, nó CSS saincheaptha chun a leithead a shocrú.
Teastaíonn .progress-barroinnt roleagus ariatréithe chun é a dhéanamh inrochtana, lena n-áirítear ainm inrochtana (ag baint úsáide as aria-label, aria-labelledby, nó a mhacasamhail).

Cuir é sin go léir le chéile, agus tá na samplaí seo a leanas agat.
