Show theme in full site

I like this theme but is it possible to show only the full content. I mean is it possible to remove the sides right and left. I made a picture and marked the parts I want to disappear so I hope s.o. can understand what I mean…

Hello there,

I hope you are doing well today.

You can use the following CSS code to remove the side area by going to Appearance > Customize > Additional CSS and pasting it there.

/*Remove sides*/
.wrapper {
    width: 100%;
    max-width: 100%;
/*Remove top*/
#branding {
    margin-top: 0px;

Best Regards,

Thank you very, very much.
