Ta’rif va qo‘llanilishi
preload atributi muallifning fikricha sahifa yuklanganda media faylni yuklash kerakmi va qanday yuklash kerakligini belgilaydi.
preload atributi muallifga brauzerga uning fikricha eng yaxshi foydalanuvchi tajribasini ta’minlaydigan variant haqida ishora berish imkonini beradi. Ba’zi hollarda bu atribut e’tiborsiz qoldirilishi mumkin.
Eslatma: Agar autoplay mavjud bo‘lsa, preload atributi e’tiborsiz qoldiriladi.
