Kodu bir siteden buldum codepen.io diye bir siteye yönlendirdi orda html css ve js kodları yazıyordu hepsini bir bir kopyala yapıştır yaptım bir klasöre koydum site alakasız şekilde açıldı.Html kodu burada html ile başlamıyor div ile başlıyor bunu nasıl düzeltirim? Kod eksik heralde html ekledim style dosyasına bağladım ama değişmedi.
