Isihloko sesihloko esisebenzisa i-H2 sisetyenziselwa izihloko eziphambili ngaphakathi kwephepha, njengaphezulu kwicandelo elikhulu. Amanye amaphepha afana nephepha/lomnikelo asebenzisa i-H2 kodwa uyihlele ukuze ibonakale yahluke kakhulu, eneneni ifana kakhulu ne-H3. Nali iphepha elisebenzisa i-H2 kwiindawo ezininzi kodwa lihlele ezinye zazo ukuze zibukeke zahluke kakhulu kwezinye: https://act.worldbeyondwar.org/activism Ukuba senza utshintsho lwehlabathi kwisitayile sesihloko esifana ne-H2 siya kufuna ukwazi ukuba izichaphazela njani iimeko ze-H2 ehlelwe ukuba ijongeke ngakumbi njenge-H3 okanye i-H5 okanye i-H6 okanye enye into. Okanye siyakufuna ukutyhutyha isiza siphela sisenza ukuba zonke iiheader zingalungiswa-okanye sisebenzise iiheader ezingalungiswanga ukuya phambili.
