How do i remove this white space when i open a empty cart on my site? URL:https://www.stbrnstudios.eu/cartPASSWORD:1234

how do i do that? 

Id like it to be like this image right here: seemine looks weird right now  How can i fix this?

i would like to have it on my home page instead of my collection page if possible?

I currently have a drawer menu for it but id like it to be on the left with each catagory under eacht other as seen in the image
