Hi, I just took a look at this and it looks like the only difference between what its showing as now and what you’re wanting is that your navigation and header aren’t full width.
If that’s what you’re wanting to change you can go into “Appearance > Customize > Layout > Navigation Layout > Full Width” to change the navigation width, and “Appearance > Customize > Layout > Header Layout > Full Width” to change your header width.
*Edit – sorry I meant Full Width, not Contained.
