Responsive Landing page using SCSS and Owl carousel

My design isn't exactly the right sizes because I didn't had figma files, I coded the project mobile first approach. I couldn't center logo in the mobile version so any suggestions are welcome. I decided to use owl carousel for slider. it is a lightweight js library to create simple carousels. It is to setup. I had to overwrite some of button's styles to be as close as possible to the design. feedbacks are welcome
