Bagaimana cara menghilangkan content particle js
Mohon bantuannya para mastah, Saya ingin menghilangkan konten yang terletak dipojok kiri atas yang sudah saya beri border kuning pada gambar. bagaimana caranya yah ? terus pada script style.css saya ganti background image nya kok ga bisa yah ? Mohon bantuannya para mastah. Terima kasih

cpba klik kanan > inspect element > deteksi disitu sumber gambar yang pojok kanan atas dari mana, dan delete bagian itu, sama dengan gambar backgroudnnya
Referensi make inspect element https://www.youtube.com/watch?v=rRWAxP0FVj8
Sudah saya inspect element tetapi saya bingung nya itu kenapa pas saya inspect element itu ada div id = stats nya. nah sedangkan saya periksa code html saya tapi gada yg namanya div id = stats
