Izindinganiso ze-WCAG

Izinga AA

Isilinganiso esincane sika 4.5:1 sombhalo ojwayelekile no-3:1 wombhalo omkhulu. Okudingekayo kwamaningi amawebhusayithi.

Izinga AAA

Isilinganiso esithuthukisiwe esingu-7:1 sombhalo ojwayelekile no 4.5:1 wombhalo omkhulu. Kunconywa ukuze kutholakalwe kalula.

Umhloli wokuphikisana kombala

Bala isilinganiso sokuphikisana kombala wombhalo nombala wangemuva.

Khetha umbala usebenzisa i-color picker yombhalo nombala we-background noma faka umbala nge-RGB hexadecimal format (isb., #259 noma #2596BE). Ungashintsha isilayidi ukukhetha umbala. I-Web Content Accessibility Guidelines (WCAG) ineseluleko esithile sokusiza nokuthi ngabe umbhalo uyafundeka yini kubasebenzisi abangabona kahle. Lezi zindlela zisebenzisa ukusebenza okubacakalayo nokwenza isilinganiso. Usebenzisa le fomula, i-WCAG ithi umbala 4.5:1 nesikhumba sowumbhalo nesidlalela esifanele umbhalo ojwayelekile, futhi umbhalo omkhulu (18+ pt ojwayelekile, noma 14+ pt obold) kufanele ube okungenani isilinganiso sikambala esingu-3:1.

Imibuzo ebuzwa njalo

Ukuze kuthobele i-WCAG AA, umbhalo ojwayelekile udinga isilinganiso sokuphikisana esingu-4.5:1 okungenani, kuyilapho umbhalo omkhulu (18pt noma 14pt ogqamile) udinga u-3:1.

I-WCAG AAA idinga izilinganiso eziphakeme zokuphikisana: u-7:1 wombhalo ojwayelekile kanye no-4.5:1 wombhalo omkhulu, uma kuqhathaniswa no-AA onezilinganiso ezingu-4.5:1 no-3:1 ngokulandelana.

Sebenzisa isici sethu sokulungisa ngokuzenzakalelayo ukulungisa umbala wombhalo noma wangemuva ngaphandle kokulahlekelwa yinjongo yakho yokuklama, noma lungisa imibala ngesandla ngezilayida ze-HSL nezimpawu zokubona ezikhombisa izindawo ezinhle kakhulu zokuthobela i-AA/AAA.

Izindawo eziluhlaza nezimaki ze-AA/AAA zikhombisa izinhla ezinhle kakhulu zokuthobela i-WCAG. Izeluleko zesiqondiso (Ukuya ekukhanyeni/Ukuya emnyameni) zikuqondisa ekuphikisaneni okungcono ngokusekelwe ekuhlanganiseni kwakho kombala wamanje.

Yebo, ungafaka noma yiliphi ikhodi lombala we-hex noma usebenzise isikhethi sombala ukukhetha imibala yakho. I-URL ibuyekezwa ngokuzenzakalelayo ukuze ukwazi ukwabelana ngezinhlanganisela zemibala ethile.
