Ibitonyanga bya Bootstrap, kurundi ruhande, byashizweho kugirango bibe rusange kandi bikurikizwa mubihe bitandukanye no kuranga imiterere. Kurugero, birashoboka gukora ibitonyanga birimo inyongeramusaruro ninyongera kugenzura, nkibice byo gushakisha cyangwa ifishi yinjira. Kubwiyi mpamvu, Bootstrap ntabwo yiteze (cyangwa guhita yongeraho) icyaricyo cyose rolenibiranga aria-bisabwa kuri ARIA nyayo . Abanditsi bagomba gushyiramo ibi biranga byihariye ubwabo.

Ariko, Bootstrap yongeramo inkunga-yubufasha bwa menu ya clavier isanzwe ikora, nkubushobozi bwo kunyura .dropdown-itemmubintu bitandukanye ukoresheje urufunguzo rwa indanga no gufunga menu ESCnurufunguzo.

Ingero

Akabuto kamwe kamanuka

Ikintu icyo aricyo cyose .btngishobora guhinduka kumanuka uhindagurika hamwe nibimenyetso byahindutse. Dore uburyo ushobora kubashyira mubikorwa hamwe <button>nibintu:
