Qalisa kabusha, iqoqo lezinguquko ze-CSS zesici esithile efayeleni elilodwa, qala i-Bootstrap ukuze unikeze isisekelo esihle, esingaguquki, nesilula ongakhela phezu kwaso.

Indlela

Qalisa kabusha yakhela phezu kwe-Nomalise, ihlinzeka ngezinto eziningi ze-HTML ezinezitayela ezicatshangelwe imibono ethile usebenzisa izikhethi zezinto kuphela. Isitayela esengeziwe senziwa kuphela ngamakilasi. Isibonelo, siqalisa kabusha ezinye <table>izitayela ukuze sithole isisekelo esilula futhi kamuva sinikeze .table, .table-bordered, nokuningi.

Nansi imihlahlandlela yethu nezizathu zokukhetha ukuthi yini ongayibhala ekuqaliseni kabusha:

Gwema margin-top. Amamajini aqondile angawa, aveze imiphumela engalindelekile. Okubaluleke nakakhulu, isiqondiso esisodwa marginsiyimodeli yengqondo elula.
Ukuze kube lula ukukala kuwo wonke amasayizi wedivayisi, ama-elementi ebhulokhi kufanele asebenzise remu-s ku- margins.
Gcina izimemezelo fontzezakhiwo ezihlobene zibe zincane, usebenzisa inheritnoma nini lapho kunokwenzeka.

Amafomu

Izakhi zefomu ezahlukahlukene ziqaliswe kabusha ngezitayela zesisekelo ezilula. Nazi ezinye zezinguquko eziphawuleka kakhulu:

<fieldset>s ayinayo imingcele, i-padding, noma imajini ukuze isetshenziswe kalula njengama-wrappers okokufaka ngakunye noma amaqembu okokufaka.

Lezi zinguquko, nokunye okwengeziwe, kuboniswa ngezansi.
