Ebyeemabega
Tuusa amakulu okuyita mu background-colorera osseeko okuyooyoota nga olina gradients.
Langi y’emabega
Okufaananako ne kiraasi za langi z’ebiwandiiko eby’omutwe, teeka ennyuma y’ekintu ku kiraasi yonna ey’ensonga. Background utilities teziteekawo ,color kale mu mbeera ezimu ojja kwagala okukozesa .text-* color utilities .
<div class="p-3 mb-2 bg-primary text-white">.bg-primary</div>
<div class="p-3 mb-2 bg-secondary text-white">.bg-secondary</div>
<div class="p-3 mb-2 bg-success text-white">.bg-success</div>

<div class="p-3 mb-2 bg-transparent text-dark">.bg-transparent</div>Okukyukakyuka okw’emabega
Nga ogattako .bg-gradientkiraasi, linear gradient eyongerwako nga ekifaananyi eky’emabega ku bifaananyi eby’emabega. Gradienti eno etandika n’enjeru etali ntangaavu (semi-transparent white) egenda wansi.
Oyagala gradient mu CSS yo eya custom? Okwongerako kyokka background-image: var(--bs-gradient);.
Sass nga bwe kiri
Ng’oggyeeko enkola ya Sass eno wammanga, lowooza ku kusoma ku bintu byaffe eby’ennono ebya CSS ebiteekeddwamu (aka CSS variables) ku langi n’ebirala.
Enkyukakyuka ezikyukakyuka
Ebisinga obungi background-colorebikozesebwa bikolebwa langi zaffe ez’omulamwa, eziddamu okuweebwa okuva mu nkyukakyuka zaffe eza langi ez’enjawulo.

Ebirungo ebitabuddwa
Tewali mixins zikozesebwa okukola background utilities zaffe , naye tulina mixins endala ez'embeera endala mw'oyagala okukola gradients zo.
