Inu simunali ochepa pa CSS imodzi yopangira gawo.
Mafilimu Amitundu Osakanikirana (CSS) amakulolani kufotokoza maonekedwe a chinthucho mwa kugwiritsira ntchito zizindikiro zomwe mumagwiritsa ntchito ku chinthucho. Zizindikiro izi zingakhale ziri ndi ID kapena kalasi, ndipo, monga zikhumbo zonse, iwo amawonjezera chidziwitso chothandizira ku zinthu zomwe zimakhudzidwa nazo. Malinga ndi chikhalidwe chomwe mumapangira chinthu, mungathe kulemba chosankha cha CSS kuti mugwiritse ntchito zofunikira zojambula zofunikira zomwe zikufunika kuti mukwaniritse mawonekedwe anu ndi webusaitiyi yonse.
Ngakhale ma ID kapena magulu akugwira ntchito kuti azigwiritsanso ntchito ndi malamulo a CSS, njira zamakono zamakono zamakono zimakondera maphunziro kupyolera mu ma ID, mbali ina, chifukwa ndizosavuta kwenikweni komanso zosavuta kugwira ntchito ndi onse. Inde, mutha kupeza malo ambiri omwe amagwiritsira ntchito ma ID, koma zizindikirozo zikugwiritsidwa ntchito mochepa kuposa kale, pamene magulu atenga masamba a masiku ano.
Maphunziro Akhaokha Kapena Ambiri mu CSS?
Kawirikawiri mungapereke chikhalidwe chimodzi pa chinthucho, koma inu simungathe kuwerengera kalasi imodzi basi momwe mulili ndi ma ID. Ngakhale chinthu chikhoza kukhala ndi chizindikiritso chokha, mukhoza kupereka gawo losiyanasiyana, ndipo nthawi zina, kuchita zimenezi kumapangitsa kuti tsamba lanu likhale losavuta komanso zosintha zambiri.
Ngati mukufuna kuyika makalasi angapo ku chigawo, mukhoza kuwonjezera makalasi ena ndikuwapatulira ndi malo mu chikhalidwe chanu.
Mwachitsanzo, ndimeyi ili ndi makalasi atatu:
