Izizathu zale meko kukuba ukusetyenziswa sheets yoyilo web ehla isimbo (SCC) ekudalweni websites Kulula kakhulu. Kwanele ukuba athwale CSS-ifayile yonke ubhaliso senginginya nodibaniso ukuba onke amaphepha kwi sayithi yakho (okanye abathile). La maphepha ziya kusoloko zikhangeleka ngokufanayo zonke. Ukuba kuyimfuneko, yenza utshintsho kuyilo ezithile iziqalelo page (i omqolo wesibini isihloko, umzekelo) kwanele tshintsho kuphela olunye ungeno kwi CSS kwifayile. Tshintsha zonke zihloko-kwinqanaba lesibini (h2) kuwo onke amaphepha iqhagamshele CSS. Ngokukodwa, ukwenza izihloko eziluhlaza ngokwaneleyo kwifayile CSS ukuba abhalise umgca enye kuphela:

h2 {sefonti-umbala: oluhlaza}
