Okutuusa amakulu mu tekinologiya ayamba

Okukozesa langi okwongera amakulu kiwa ekiraga ekirabika kyokka, ekitajja kutuusibwa eri abakozesa tekinologiya ayamba – gamba ng’ebisoma ku ssirini. Kakasa nti amawulire agalagirwa langi oba geeyoleka okuva mu birimu byennyini (okugeza ekiwandiiko ekirabika), oba gateekebwamu okuyita mu ngeri endala, gamba ng’ebiwandiiko ebirala ebikwekebwa ne .visually-hiddenkiraasi.

Lemesa okuzinga ebiwandiiko

Bw’oba toyagala biwandiiko bya bbaatuuni kuzinga, osobola okwongera .text-nowrapekibiina ku bbaatuuni. Mu Sass, osobola okuteekawo $btn-white-space: nowrapokulemesa okuzinga ebiwandiiko ku buli bbaatuuni.

Ebiwandiiko ebiraga obutambi

Ebika .btnbikoleddwa okukozesebwa ne <button>elementi. Naye, osobola n’okukozesa kiraasi zino ku <a>oba <input>elementi (wadde nga browser ezimu ziyinza okukozesa rendering eyawukana katono).

Nga okozesa ebika bya button ku <a>elementi ezikozesebwa okutandikawo emirimu mu lupapula (nga okugwa ebirimu), okusinga okuyunga ku mpapula empya oba ebitundu munda mu lupapula oluliwo kati, enkolagana zino zirina okuweebwa a role="button"okutuusa obulungi ekigendererwa kyazo eri tekinologiya ayamba nga ebisoma ku ssirini.
