• Ku andlariwile switirhisiwa swa nkombiso wo gandlisa leswi kumekaka ku fambisana na switirhisiwa swin’wana. Beta 3 na ku tlula ntsena a va ri na block, inline-block, inline, na none. Stable v4 yi engeteriwile flex, inline-flex, table, table-row, na table-cell.

• Ku hundzuluxiwa ka xikombiso xa le mahlweni xa ku gandlisa loku lulamisiweke eka swihlamusela-marito hinkwaswo leswi nga ni switayele leswintshwa swo gandlisa leswi hlamuselaka @page size.

Beta 3 yi cinca

Loko Beta 2 yi vonile vunyingi bya ku cinca ka hina loku tshovekaka hi nkarhi wa xiyenge xa ​​beta, kambe ha ha ri na swi nga ri swingani leswi a swi lava ku lulamisiwa eka nkandziyiso wa Beta 3. Ku cinca loku ku tirha loko u pfuxeta eka Beta 3 ku suka eka Beta 2 kumbe vuhundzuluxeri byihi na byihi bya khale bya Bootstrap.

Swo hambana

• Ku susiwile $thumbnail-transitionxihlawulekisi lexi nga tirhisiwangiki. A hi nga ri eku hundzuleni ka nchumu, kutani a ku ri khodi yo engetela ntsena.
