Talaaga
Tu'u atu le uiga background-colorma fa'aopoopo le teuteuga fa'atasi ma fa'alili.
Lanu i tua
E tutusa ma vasega lanu o tusitusiga, seti le talaaga o se elemene i soʻo se vasega faʻamatalaga. E le seticolor mea aoga i tua , o lea i nisi tulaga e te manaʻo e faʻaoga .text-* mea faʻaoga lanu .

E ala i le fa'aopoopoina o se .bg-gradientvasega, ua fa'aopoopoina ai se fa'alili laina e fai ma ata pito i tua i tua. O lenei fa'alili e amata ile pa'epa'e semi-manino lea e mou atu i lalo.
E te mana'omia se gradient i lau CSS masani? Fa'aopoopo background-image: var(--bs-gradient);.
Opacity
Fa'aopoopo i le v5.1.0
E pei o le v5.1.0, background-coloro mea aoga e gaosia ma Sass e faʻaaoga ai fesuiaiga CSS. Ole mea lea e fa'atagaina ai suiga ole lanu ile taimi moni e aunoa ma le tu'ufa'atasia ma suiga fa'amanino ole alpha.
E faapefea ona galue
Mafaufau i la matou fa'aoga fa'aletonu .bg-success.
.bg-success {
--bs-bg-opacity: 1;
background-color: rgba(var(--bs-success-rgb), var(--bs-bg-opacity)) !important;
}
Matou te faʻaogaina se RGB version o la matou --bs-success(faʻatasi ai ma le tau o le 25, 135, 84) CSS fesuiaiga ma faʻapipiʻi se fesuiaiga CSS lona lua, --bs-bg-opacity, mo le faʻamalamalamaina o le alafaʻa (faʻatasi ai ma se tau le aoga 1faʻafetai i se fesuiaiga CSS i le lotoifale). O lona uiga o so'o se taimi e te fa'aogaina .bg-successnei, o lau colortau fa'atatau o le rgba(25, 135, 84, 1). Ole suiga ole CSS ile lotoifale i totonu ole .bg-*vasega ta'itasi e aloese mai fa'afitauli tau tofi ina ia le otometi le fa'aogaina ole fa'aoga ole fa'aoga ole alafa.
Faataitaiga
Ina ia suia lena opacity, soloia --bs-bg-opacitye ala i sitaili masani poʻo sitaili laina.
<div class="bg-success p-2 text-white">This is default success background</div>
<div class="bg-success p-2" style="--bs-bg-opacity: .5;">This is 50% opacity success background</div>Po'o, filifili mai so'o se .bg-opacitymea aoga:
<div class="bg-success p-2 text-white">This is default success background</div>
<div class="bg-success p-2 text-white bg-opacity-75">This is 75% opacity success background</div>
<div class="bg-success p-2 text-dark bg-opacity-50">This is 50% opacity success background</div>
<div class="bg-success p-2 text-dark bg-opacity-25">This is 25% opacity success background</div>
<div class="bg-success p-2 text-dark bg-opacity-10">This is 10% opacity success background</div>Sass
I le faaopoopo atu i le Sass o loʻo mulimuli mai, mafaufau e faitau e uiga i a matou mea faʻapitoa a le CSS e aofia ai (aka CSS fesuiaiga) mo lanu ma isi mea.
