Sorry for the late reply. I was busy with my studies and now backs to my web development program. Thanks Yashika for the hint, but it does not help. I do not know why there is a scroll bar appearing at the horrizontal bottom. Any help?

I am learning website development and stuck at a point. After completing the webpage, I can see a horrizontal scrollbar at the bottom of the window. I am not sure why this issue. Is there any method to find the div or element that is breaking my web design and causing this horrizontal scrollbar?
