+در یک گزارش توضیح دهید چرا استفاده از این ساختار سلسله مراتبی بهتر از استفاده از یک تگ خاص مانند Div برای همه المان ها است؟
+به چند دلیل استفاده از این ساختار معنایی بهتر از استفاده از div المنت های معنادار که در HTML5 اضافه شدند، محتوایی که قرار هستند رو مورد نمایش قرار بگیرد را توصیف می کنند. خوانایی html برای برنامه نویس راحت تر می کنه. دوما افراد دارای محدودیت که از اسکرین ریدر استفاده می کنند، دستگاهشون بهتر می تونه محتوای داخل صفحه رو بفهمه و تجربه بهتری برای این افراد ایجاد میشه. سوما موتورهای جستجو برای این المنت های معنادار اهمیت قائله و در صورت استفاده درست از آنها امتیاز قائل میشه و در نتیجه SEO بهتری خواهیم داشت.
