Grupp ta' input
Estendi faċilment il-kontrolli tal-formola billi żżid test, buttuni, jew gruppi ta 'buttuni fuq kull naħa ta' inputs testwali, selezzjonijiet personalizzati, u inputs ta 'fajls apposta.
Eżempju bażiku
Poġġi add-on jew buttuna waħda fuq kull naħa ta' input. Tista' wkoll tpoġġi waħda fuq iż-żewġ naħat ta' input. Ftakar li poġġi <label>
s barra mill-grupp ta' input.

Tgeżwir
Gruppi ta 'input jingħalqu awtomatikament permezz flex-wrap: wrap
sabiex jakkomodaw validazzjoni tal-qasam tal-formola tad-dwana fi ħdan grupp ta' input. Tista' tiddiżattiva dan b' .flex-nowrap
.

Daqs
Żid il-klassijiet tad-daqs tal-forma relattiva mal- .input-group
istess u l-kontenuti fi ħdanhom awtomatikament jerġgħu jinbidlu—m'hemmx bżonn li tirrepeti l-klassijiet tad-daqs tal-kontroll tal-formola fuq kull element.
Id-daqs fuq l-elementi tal-grupp tad-dħul individwali mhuwiex appoġġjat.

Aċċessibilità
Jiżguraw li l-kontrolli tal-formoli kollha jkollhom isem aċċessibbli xieraq sabiex l-iskop tagħhom ikun jista’ jitwassal lill-utenti tat-teknoloġiji ta’ assistenza. L-aktar mod sempliċi biex jinkiseb dan huwa li tuża <label>
element, jew—fil-każ ta’ buttuni—li tinkludi test deskrittiv biżżejjed bħala parti mill- <button>...</button>
kontenut.
Għal sitwazzjonijiet fejn mhux possibbli li jiġi inkluż <label>
kontenut ta' test viżibbli jew xieraq, hemm modi alternattivi kif xorta jiġi pprovdut isem aċċessibbli, bħal:
<label>
elementi moħbija bl-użu tal- .visually-hidden
klassi
Tipponta lejn element eżistenti li jista 'jaġixxi bħala tikketta bl-użuaria-labelledby
Jipprovdi title
attribut
Issettjar espliċitament l-isem aċċessibbli fuq element bl-użuaria-label
Jekk l-ebda wieħed minn dawn ma jkun preżenti, it-teknoloġiji ta' assistenza jistgħu jirrikorru għall-użu tal- placeholder
attribut bħala riżerva għall-isem <input>
u l- <textarea>
elementi aċċessibbli. L-eżempji f'din it-taqsima jipprovdu ftit approċċi ssuġġeriti u speċifiċi għall-każ.
Filwaqt li l-użu ta' kontenut moħbi viżwalment ( .sr-only
, aria-label
, u anke placeholder
kontenut, li jisparixxi ladarba qasam ta' formola jkollu kontenut) se jkun ta' benefiċċju għall-utenti tat-teknoloġija assistiva, nuqqas ta' test ta' tikketta viżibbli xorta jista' jkun problematiku għal ċerti utenti. Xi forma ta' tikketta viżibbli hija ġeneralment l-aħjar approċċ, kemm għall-aċċessibbiltà kif ukoll għall-użabilità.
