Bootstrap ewagira ebifulumizibwa ebisembyeyo, ebitebenkedde ebya browser ne platforms zonna enkulu.

Browser endala ezikozesa enkyusa ya WebKit, Blink, oba Gecko eyasembyeyo, oba butereevu oba nga ziyita mu API y’okulaba omukutu ku mukutu, teziwagirwa mu bulambulukufu. Naye, Bootstrap erina (mu mbeera ezisinga) okulaga era okukola obulungi mu browser zino nazo. Ebisingawo ebikwata ku buyambi biweereddwa wansi.

Tukozesa Autoprefixer okukwata obuwagizi bwa browser obugendereddwa nga tuyita mu CSS prefixes, ekozesa Browserslist okuddukanya enkyusa za browser zino. Weebuuze ku biwandiiko byabwe ku ngeri y’okugatta ebikozesebwa bino mu pulojekiti zo.

Ebyuma ebikozesebwa ku ssimu

Okutwaliza awamu, Bootstrap ewagira enkyusa ezisembyeyo eza buli mukutu omukulu ogwa browser ezisookerwako. Weetegereze nti proxy browsers (nga Opera Mini, Opera Mobile's Turbo mode, UC Browser Mini, Amazon Silk) teziwagirwa.

Internet Explorer

Internet Explorer tewagirwa. Bw’oba weetaaga obuwagizi bwa Internet Explorer, nsaba okozese Bootstrap v4.

Modals ne dropdowns ku ssimu

Okujjula n’okuyiringisibwa

Obuwagizi bwa overflow: hidden;ku <body>elementi bukoma nnyo mu iOS ne Android. Ku nsonga eyo, bw’oyita waggulu oba wansi ku modal mu bumu ku bbulawuzi z’ebyuma ebyo, <body>ebirimu bijja kutandika okutambula. Laba ekizibu kya Chrome #175502 (ekitereezeddwa mu Chrome v40) n'ekizibu kya WebKit #153852 .

Ennimiro z’ebiwandiiko bya iOS n’okutambula

Okuva ku iOS 9.2, nga modal eggule, singa okukwata okusooka okw’akabonero k’omuzingo kuba mu nsalo y’ekiwandiiko <input>oba a <textarea>, <body>ebirimu wansi wa modal bijja kuyiringisibwa mu kifo kya modal yennyini. Laba ekizibu kya WebKit #153856 .

Element .dropdown-backdroptekozesebwa ku iOS mu nav olw'obuzibu bwa z-indexing. Bwe kityo, okuggalawo ebigwa mu navbars, olina okunyiga butereevu ekintu ekigwa wansi (oba ekintu ekirala kyonna ekijja okukuba ekintu ekinyiga mu iOS ).

Okuzimba kwa Browser

Okuzimba omuko tekyewalika kwanjula ebikozesebwa mu kulaga mu bitundu ebimu, byombi mu Bootstrap n’omukutu gwonna. Okusinziira ku nsonga, tuyinza okusobola okugitereeza (sooka onoonye n’oluvannyuma oggulewo ensonga bwe kiba kyetaagisa). Naye, tutera okubuusa amaaso bino kuba bitera obutaba na solution butereevu okuggyako hacky workarounds.

Abakakasa

Okusobola okuwa obumanyirivu obusinga obulungi eri browser enkadde n’erimu obuzibu, Bootstrap ekozesa CSS browser hacks mu bifo ebiwerako okutunuulira CSS ey’enjawulo ku browser versions ezimu okusobola okukola ku bugs mu browsers zennyini. Hacks zino kitegeerekeka kireetera abakakasa CSS okwemulugunya nti si ntuufu. Mu bifo bibiri, era tukozesa bleeding-edge CSS features ezitannaba kutuuka ku mutindo mu bujjuvu, naye bino bikozesebwa purely for progressive enhancement.

Okulabula kuno okw’okukakasa tekulina makulu mu nkola okuva ekitundu ekitali kya hacky ekya CSS yaffe bwe kikola okukakasa mu bujjuvu era ebitundu ebiriko hacky tebiyingirira nkola nnungi ey’ekitundu ekitali kya hacky, y’ensonga lwaki tubuusa amaaso mu bugenderevu okulabula kuno okw’enjawulo.

Ebiwandiiko byaffe ebya HTML nabyo birina okulabula okumu okutali kwa makulu era okutali kwa mugaso ku kukakasa HTML olw'okussaamu kwaffe eky'okugonjoola ekizibu ekimu ekya Firefox .
