Sahifa maketini tejash bilan birga bo'limlar va pastki bo'limlarning tuzilishini yanada aniqroq ko'rsatish uchun saytni joylashtirishda ochiladigan pastki menyu bo'limlari bo'lgan menyudan foydalaniladi. Bunday mexanizmni amalga oshirish unchalik qiyin emas: amalga oshirish misollaridan biri maqolada keltirilgan.

Agar siz allaqachon eskirgan brauzer modifikatsiyasini qo'llab-quvvatlash uchun ushbu parametrdan foydalanmoqchi bo'lsangiz, unda uslub tavsiflari blokiga qo'shimcha satr qo'shilishi kerak (darhol keyin) (sharh qo'shishingiz shart emas):
/ * eski IE brauzerlari uchun * /
