Dizayini leyi pfuxetiweke

Bootstrap v5.2.0 yi kombisa ku pfuxetiwa ka dizayini leyi nga vonakiki ya swiphemu swi nga ri swingani na swihlawulekisi eka phurojeke hinkwayo, ngopfungopfu hi ku tirhisa border-radiusmimpimo leyi antswisiweke eka swikomba-nkarhi na vulawuri bya xivumbeko . Maphepha ya hina na wona ya pfuxetiwile hi pheji leyintshwa ya le kaya, layout yo olova ya tidokisi leyi nga ha pfurhiki swiyenge swa barhi ya le tlhelo, na swikombiso leswi vonakaka swinene swa Swifaniso swa Bootstrap .

Swilo swo tala leswi cinca-cincaka swa CSS

Hi pfuxetile swiphemu swa hina hinkwaswo ku tirhisa swilo leswi cinca-cincaka swa CSS. Loko Sass ya ha seketela hinkwaswo, xiphemu xin’wana na xin’wana xi pfuxetiwile ku katsa swilo leswi cinca-cincaka swa CSS eka titlilasi ta xisekelo ta xiphemu (xikombiso, .btn), leswi pfumelelaka ku cinca-cinca lokukulu ka nkarhi wa xiviri ka Bootstrap. Eka minkandziyiso leyi landzelaka, hi ta ya emahlweni hi ndlandlamuxa matirhiselo ya hina ya swilo leswi cinca-cincaka swa CSS eka xivumbeko xa hina, tifomo, vapfuni, na switirhisiwa. Hlaya swo tala hi swilo leswi cinca-cincaka swa CSS eka xiphemu xin’wana ni xin’wana eka matluka ya swona ya matsalwa hi ku hambana ka swona.

Ku tirhisiwa ka hina ka CSS variable ku ta va ku nga helelanga hi ndlela yo karhi ku fikela eka Bootstrap 6. Hambileswi hi nga tsakelaka ku tirhisa leswi hi ku helela eka bodo hinkwayo, swi endla ekhombyeni ro vanga ku cinca loku tshovekaka. Xikombiso, ku veka $alert-border-width: var(--bs-border-width)eka khodi ya hina ya xihlovo swi tshova Sass leyi nga kotekaka eka khodi ya wena loko a wu endla $alert-border-width * 2hi swivangelo swo karhi.

Hi ndlela yaleyo, laha swi kotekaka kona, hi ta ya emahlweni hi susumeta ku ya eka swilo swo tala leswi cinca-cincaka swa CSS, kambe hi kombela u lemuka leswaku ku tirhisiwa ka hina ku nga ha va ku ringaniseriwile nyana eka v5.

Xintshwa`_maps.scss`

Bootstrap v5.2.0 yi nghenise fayili leyintshwa ya Sass leyi nga na _maps.scss. Yi humesa mimepe yo hlayanyana ya Sass ku suka eka _variables.scssku lulamisa mhaka laha ku pfuxetiwa ka mepe wo sungula ku nga tirhisiwangiki eka mimepe ya vumbirhi leyi yi andlalaka.
